Re: [Elecraft] Minimum bandwidth?

[PKA]

The key question is always latency.

Maybe the problems Lynn refers to is more due to very high jitter.

In my experience fairly high latency *can* be used - if the jitter is low. It 
will not make you feel like being directly on the rig and you may have to adapt 
your operating style.
But high jitter is hard to cope with mainly because the programs may stop and 
you need to re-start. It will drive you mad.

My non-scientific experience is: Programs like IP-Sound, HRD, TeamViewer, 
KPA500 and KAT500 remote software will suffer first. Other programs like 
WKRemote and K3iNetwork annd Skype are more robust (dont recall ever having had 
to restart WKRemote due to jitter).

I wonder what makes the difference. Maybe related to buffer control or some 
programs using TCP/IP and others UDP?

Ignore the faster speed, it's the slower speed on non-symmetric service.

The key question is always latency.

You can check out a VoIP calculator if you want to play the numbers, but most 
VoIP (and most cellular service) run around 8 kilobits/second.  No one offers 
IDSL service anymore, but it'd work beautifully at 128k (symmetric) with 
bandwidth to spare.

Where the problem lies is in the way the line is provisioned.

Where I live, there is only one provider that's worthwhile, the local 
telco.simply doesn't have enough bandwidth from the local central office to 
their first router.  The cable company doesn't admit they have service, even 
though there is a drop to the house.

That doesn't stop the Telco from selling 7 megabit service -- over and over and 
over.

So, sometimes I get 7 millisecond pings.  A lot of the time it's single digits, 
but every minute it'll jump over 500 msec.  Right now it's averaging about 250 
msec, and the maximum has been 998 msec.

I've seen more than 4000 msec. (4 seconds).

Imagine trying to snag some amazing DX, and having the audio just stop for four 
seconds.

I could buy a faster wire, but they won't add bandwidth from the C.O. to the 
rest of the internet, so the latency would be the same.  I'd buy slower if they 
offered it.

Re: [Elecraft] Ignore my previous post on Satellite Internet

[PKA]

Don
My experience is that the biggest problem would be jitter. Oli is correct that 
you can operate RC over a 128 kbps link. But you can also operate RC over 
fairly high latency links - it wont give you a "smooth" feeling when tuning 
across the band- the VFO dial will seem to be connected via a rubber band. But 
it is something you (some at least - and I for one) can adapt to. I have tried 
it extensively over the years, started using RC over 10years ago. I would not 
call it unusable if the alternative is nil. If you have alternatives its 
another matter. I have QSOed with this iPad from a Norwegian flight (from EA8 
to OZ) and while it was not too "smooth" it was definitely useful and a lot of 
fun.

But if you have high jitter it is my experience that RC does not work 
satisfactorily. At least the software must be written with high jitter in mind. 
If not, the software may drop out frequently driving you crazy and its my 
experience that VoIP based on TCP/IP will not work well.

My guess is that with a 10 Mbps connection you are likely to have low jitter 
and you will be just fine. Your XYL can enjoy streaming video on the same link 
with no problem and you wont have any "local QRM" during your QSOs. Have fun!

If you want to save the 300$ you can operate remotely from laptop, iPad or

Re: [Elecraft] Logging Programs

[PKA]

Terry
My advice is that you try several of the free logging programs for some time 
and then decide which one you like the best. You can see from the answers that 
not one logging program fits all. It very much is a matter of taste. It should 
be very easy to move your log from any one logging system to another, so you 
dont have to worry about missing logged QSOs. I have used the free version HRD 
for many years and it fits my needs. I use another logging system (Ham 
Quicklog) on this iPAD (when operating RC from the iPAD) and from time to time 
I "synchronize"  the HRD and Ham Quicklog logs. Takes a few minutes but no 
sweat.

Re: [Elecraft] LDEs (Long-Delayed Echos)

[PKA]

Hi Ted
You can hear quite strong echoes on low bands (maybe up to about 5MHz as far as 
I remember). Signals follow earth magnetic field - bouncing back when they 
reach the southern hemisphere -  and the delay therefore depends on your 
magnetic latitude (distance from the magnetic pole). It is quite a long path 
and for my QTH the delay is 237 msec which is so long that it is easy to hear 
your own echo with any modern rig. In fact you would think someone is jamming 
you until you find out its yourself! The phenomenon has been researched and is 
well understood.

It seems to occur around winter solstice and I have heard it several times, 
mostly 4 to 5 hours after sunset. I wrote an article about it in QST Nov 2009 
(Observation of Long Delayed Echoes on 80 Meters) and I can send you a copy if 
you mail me off-list. I can also send you an audio recording so you can hear 
what it sounds like. Anyone else who wants a copy (article and/or sound 
recording) please contact off-list.

Good luck - I expect chances will be best on 80m in a few weeks time from now 
on until around February.

Re: [Elecraft] WBN: KPAxxx Remote Automatic Reconnect

[PKA]

I agree it might be useful. Although is rarely happens here - most days it does 
not happen at all - but once in a while it does happen repeatedly.
When it happens I think it is due to some kind of occasional interference on 
the 2,4 GHz WiFi.

However, it is very interesting that whenever my KPA- and KAT Remote Clients 
disconnect, the same thing normally (not always) happens to the HRD Remote 
Client *but never* to the Winkey Remote Client.
If some Server/Client programs are more robust than others I would rather see 
the not-so-robust ones be made more robust than solving the problem by  
incorporating an automatic reconnect.

Can others confirm my observations - and if so can someone here explain why the 
WK Server/Client is more robust than KPA/KAT and HRD Server/Client?

Both KPA500 Remote Client and KAT500 Remote Client have a tendency to lose 
connection to their respective servers here at N6XI and have to be commanded 
manually to reconnect. This happens every few hours, usually both at the same 
time. My other client-server pair (PstRotatorAz) connects automatically using 
last-known parameters whenever the client starts and appears to maintain 
perpetual connection, although I suspect it may be dropping and reestablishing 
that connection transparently. Any chance of revising KPAxxx Remote to do the 
same? It sure would be nice!

The normal PC to K2 to KAT100 cable *is* a Y cable of sorts, look in the

It is not possible to get it backwards because the PC end has female pins while 
the KAT100 end has male pins.
The only problem that could occur with a properly made cable is that the 
connectors could be swapped between the K2 and the KAT100.
The connector with 2 cables in it must connect to the K2 - if backwards, the 
KAT100 will work fine, but the PC connection will not.

I'd say Oliver is right. The basic K3 is so good that you will not really 
notice the difference for your use. You wont even have any problem if you start 
chase difficult DX. You will never have to give up copying a rare CW DX station 
even in difficult situations just because you didnt have the low noise synth

Re: [Elecraft] K3/0-Mini - Experiences?

[PKA]

It all depends on what you want to achieve.

There are many different reasons for hams to want to operate RC. Different 
requirements probably call for different solutions.

If you want to operate your home rig (or for that matter a real remote rig) 
when you are not at home, eg. when travelling, it might be both expensive and 
unpractical using the K3/0-Mini and RemoteRig set. Expensive or not depends on 
your financial situation of course. But you will spend something like 1270 USD 
and you will have to carry around some boxes and cables etc. But you have the 
luxury of having a very attractive man/machine interface!

Re: [Elecraft] K3/0-Mini - Experiences?

[PKA]

I use one of three different solutions:

1. From a laptop I use two Winkeyers connected over IP via K1EL WKremote 
Server/Client programs. Keying may be either using a paddle or using the laptop 
keyboard. Alternatively it is possible to use only one Winkeyer at the remote 
rig and input by keyboard via Teamviewer. Audio is based on IP-Sound which is 
excellent for CW ( superior to Skype).

2. From an iPad or iPhone I use an app called K3iNetwork made by Mike KS7D. 
Keying using the keypad. You can even use voice input to the iPhone/iPad (and 
key your rig) using SIRI, but this is not yet useful and needs some more work 
on the app. But it could be developed to be an interesting mode for RC 
operation from a moving car. Audio based on Skype.

3. From an iPad or iPhone I use an app called K3iDitDah also made by Mike. 
Keying is done using the touch screen in a way like touch-type paddling. 
Although this app can be used as it is now it still does need some development 
work. Audio based on Skype.

NB: It is possible to switch between solution 1 and 2 (or 3) on the fly while 
receiving!

It all depends on what you want to achieve.

There are many different reasons for hams to want to operate RC. Different 
requirements probably call for different solutions.

If you want to operate your home rig (or for that matter a real remote rig) 
when you are not at home, eg. when travelling, it might be both expensive and 
unpractical using the K3/0-Mini and RemoteRig set. Expensive or not depends on 
your financial situation of course. But you will spend something like 1270 USD 
and you will have to carry around some boxes and cables etc. But you have the 
luxury of having a very attractive man/machine interface!

Still for the traveller: If you want an inexpensive solution, if you can accept

Re: [Elecraft] Audio latency issues in remote stations.

If you operate CW you also must consider that there will be a contribution to 
the overall latency from the buffering in the key system. When you use two K1EL 
Winkeyers connected over IP you have additional latency because the local 
winkeyer is decided before the character is sent over IP.
Still remote CW works just fine for most QSOs.

Re: [Elecraft] Audio latency issues in remote stations. Specific for CW.

[PKA]

Richard

This is only of interest to CW operators.

The latency (the time from when you send a character from Your paddle to the 
local PC until the remote rig starts to transmit this character) will be about 
half a second (500 milliseconds!) plus the internet delay. My understanding is 
that this delay at least partly is caused by the decoding of the paddle input. 
I did not measure this but I have used two connected Winkeyers for some time 
and that is my experience.

When you use the keyboard as an input to the local winkeyer it corresponds to 
using a paddle input with very fast keying. In both cases (paddle or keyboard) 
you can input so fast that you constantly are a little ahead of the transmitted 
stream. That in fact is necessary for perfect CW. Therefore, break-in CW is a 
little easier using the keyboard rather than the paddle. However this only 
applies to a system based on local decoding (Winkeyer). The Remoterig system 
may be better in this respect- I have no experience with Remoterig.

Of course if you have a poor internet quality (high latency or high jitter) 
this might be the limiting factor. Remote operation is no fun with bad internet 
quality! But you can definitely make fine CW QSOs even over a satellite link 
(ping time 600 msec). High latency is not too much of a problem - you can get 
used to it (in my view after using remote CW for ten years). But high jitter is 
a PITA.

If you have a good internet quality (say latency around 30-50 msec)  you will 
feel annoyed by the buffer latency,  especially if you try to operate 
break-in using paddles. You will need to be prepared to stop transmission 
(cursor placed over the stop button in the Winkeyer window ready for you to 
left-click in order to stop immediately). This IS possible but NOT easy to do.

 Paul, thanks.  The latency between the two keyers is a variable (depending on 
 the locations of the two keyers), but the K1EL keyer latency should be some 
 standard latency times two.  Any idea how much that standard keyer latency 
 would be?
 
 I'm interested in adding up the latency contribution from the basic 
 components to understand how each part contributes to the total latency.  
 I'll initially be most interested in voice, but then in CW and perhaps 
 eventually in RTTY.  This is mostly a thought exercise at the moment.
 
 There is a kickstarter going for an audio interface with less than 3 
 millisecond internal latency.  It is designed for internet music jam 
 sessions.  My current equipment (including a router) seems to have about 18 
 ms latency and a total latency between two players seems to need to be less 
 than about 25-30 ms for two or more to play together across the internet.  So 
 add internet latency and can't play with folks outside the West Coast. This 
 all got me thinking about remoting radio and whether there might be a dual 
 use for this Jam Blaster.

[Elecraft] [K3] Useful fw feature

[PKA]

When switching OFF the K3 remotely, you need to send the PS0 command before you 
switch OFF the PSU. To switch ON again you need first switch ON your PSU and 
then  and then briefly ground pin 8 of the ACC. However with some devices with 
relay control via GSM/SMS (which is what I am using) you can close and open 
relays, but there may not be available an automatic brief relay closure. What I 
do is simply to always open the Pin 8 relay after sending PS0 and before 
switching OFF the PSU. The only way I can be sure that the Pin 8 relay has 
opened is by listening for a very weak hump in the audio, indicating that the 
K3 has switched OFF. If I am in doubt (which may easily happen in noisy 
environments) I have to send a relay-status request by SMS. Therefore it would 
be a help if the K3 could produce an audible dit as the very last thing 
before it switches OFF.

For clarity the sequence I use is as follows:

Switch ON

1)  SW ON PSU

2)  Close Pin 8 relay
Switch OFF

1)  Send PS0

2)  Open Pin 8 relay

3)  Listen carefully for K3 switching OFF

4)  SW OFF PSU

I just got used to do it this way - maybe there are smarter ways.
But doing it this way, it would be a great help if the K3 could make an audio 
dit just before it switches OFF.

Would this be annoying for most users? If so it might be made selectable.

Poul-Erik, OZ4UN

I Can recommend the Elecraft sw for control of both KPA and KAT. Using it via 
Teamviewer and HRD (both available as freeware) You Can easily control the

Re: [Elecraft] K3 front panel encoders

[PKA]

For a Danish ham warranty repair shipping would be
repair in Italy
5kg parcel (K3) 2*46 = 92 USD
repair in USA
5kg parcel (K3) 2*85 = 170 USD

repair in Italy
15kg parcel (KPA500) 2*92= 184 USD
repair in USA
15kg parcel (KPA500) 2*206= 412 USD

So its about half Price shipping for repair in Italy, probably something 
similar from Sweden.
But it is still quite expensive in my view.

What are the shipping cost for warranty repair for a (Con)US ham?

[Elecraft] OT: CQWW CW with K3 and KPA500

[PKA]

Great combo.  Operated 80m for 30 hours with a high duty cycle. KPA temp 
stabilized at 50C with low level fan going ON and OFF. Smooth and very 
satisfying!

Re: [Elecraft] How do I turn OFF my K3 remotely

[PKA]

John
You can send the PS0 command from HRD:
MacrosDisplayCAT Comands ( PS0).
You will hear that the K3 audio stops and you can then switch OFF the K3 by 
briefly shorting ACC pin 8 to ground.
I use GSM SMS to do that (and subsequently to switch OFF the PSU). An IP power 
switch may be simpler, but I like to be able to switch everything OFF also if 
my router goes dead.

One slight problem is that you need to be sure that pin8 has been grounded and 
the K3 has been switched OFF before you switch OFF the PSU. I do that by very 
carefully listening to the audio (Skype or IP-Sound). But in some cases there 
may be some delay in delivery of SMS and it may be difficult to ensure that pin 
8 has really been shorted ( and you may want to request the relay status by yet 
another SMS!) But there is a very weak change in the audio noise level when 
pin8 is pulled to ground and when you hear that you know you can safely switch 
OFF the PSU.

If someone from Elecraft reads this, I suggest to include in a future firmware 
upgrade something which makes the K3 audio make a beep when pin 8 is pulled 
down and K3 switches OFF.

 John,
 
 I don't know if or how that HRD does it, but remote power off is available if 
 the software issues a PS0; command to the K3.  Note that a powered off K3 is 
 not listening to commands, there is no way to turn the K3 on via RS-232 
 command.  To turn the K3 back on remotely, an external device must pull the 
 ACC connector pin 8 to ground.  That may require additional hardware at the 
 remote site.

 Can someone tell me how to turn OFF my K3 radio remotely through HRD.
 All I could find in the archives was this simple statement.
 
 From HRD If one wants to get fancy, you can even shut down
 the K3 using the Power off command through the serial communications
 port, and then shut down the computer too.
 
 Well no other explanation was given. So that might be fine for some
 computer expert but doesn't tell me anything other than yes it is possible.
 Can someone point me to a step by step instructions on how to turn off the
 K3 radio by remote?

Re: [Elecraft] K3 -- turning it off

[PKA]

This would happen if pin-8 of the ACC connector is shorted when you hit the 
power button. The same thing happens when you send the PS0 command.

 Anyone have any ideas why, when I hit the power button to turn off my K3, it 
 doesn’t turn off.  All markings disappear but the backlight stays on and 
 hitting the power button thereafter does nothing. 
 
 I have to resort to pulling the plug.  
 
 On plugging it back in, the power comes on without hitting the power button.

Re: [Elecraft] Import Costs from America

[PKA]

Hi Jim
Yes I saw that coming, but you are missing the point.
No Jim, all I ask for is that *for warranty repair* that the manufacturer pays 
for the return shipping. I believe that is normal commercial practice (also for 
other US manufacturers).

It should (hopefully) not be a big financial burden for the manufacturer. 
Depending of course on the quality of his product and the number of units 
needing repair during the warranty period.

I did not see anyone giving a figure of how many KPA500 and KAT500 units have 
been needing warranty repair. Maybe Elecraft could enligthen?

I didn't see anybody question the quality of repair. You confuse the issue!
However you like to argue, there is a fact. For warranty repair, shipping costs 
are higher for non US customers than for US customers first of all because 
Elecraft only pays the shipping both ways for US customers - even when the 
repair is done locally from Elecraft in EU (=Italy for EU)

 If you buy the kit version, you will be familiar with the way to dismantle

My experience though 7 years of Remote operating (CW) is that Teamviewer is

You Can make a Remote set up without the K3/0 and RemoteRig at a very low cost. 
It may be satisfying your needs. I have a description of my set up on my QRZ

At this very moment QRV with K3 and KPA500 at home from Holidays in the South

[Elecraft] KPA500 power fluctuations

[PKA]

For a while I have noticed that the KPA output indikations on both THE LEDs and 
the LCD display is fluctuating. The highest LED is flickering and the last two 
digits of the LCD are also fluctuating (hard to read, but at 500W it varies 
about 10W I think). It is the same at any power level from 20W to 500W. It is 
the same with the amp ON and STBY, so it seems to be a problem in the power 
monitoring circuit.

It is certain that the fault is in the KPA. I had another KPA connected to the 
K3 and its power indication was steady - just like they were on my own KPA 
until a few months ago. It is the same whether the amp is connected to a dummy 
load or an antenna and I dont hear anything unusual listening on a monitoring 
K2.

I did not yet have an opportunity to look at the power envelope on an 
instrument. So I dont know if the flickering is random like noise or not.

I thought that may be someone else on this list has seen this fault and might 
explain what's wrong.

The diode shows 10Mohm in one direction and 2-3 Mohm (varying) in the other 
direction (DVM)
Where is this diode located (if there are several, then where?), what is its 
function and is it replaceable by a skilled tech person?
What could be the reason for the failure - it does not appear to have been 
over-heated, so desoldering appears not logical.

Is there a diagram of the KPA500 available?

Re: [Elecraft] KPA500 T/R Switch Failure

[PKA]

My KPA500 T/R switch failed after two weeks of operation. Can not pinpoint any 
reason why it should fail. It was repaired by Elecraft under warranty in Italy 
and has now worked 10 weeks with no problem.

I now always check VSWR on K3 and on KPA with KPA in STBY whenever i operate on 
a new band and always have the KPA in STBY when I let the KAT500 tune. It is a 
bit cumbersome but really not a big deal.

I would be surprised if I were the only one having had a failing KPA500 T/R 
switch.

NB: Europeans sending their failed Elecraft gear for repair at the Elecraft 
associate in Italy must pay for the shipping BOTH ways. This is clearly poorer 
customer service than what Elecraft provided for its US customers.

Emne: [Elecraft] Remote operation of a K3

Hi all;

I would like to remote my K3 station via the internet.  With out spend lots of 
money.

I know there are several programs available that clam remote operation but they 

don't tell you what else you got to buy.  


Back in the 90's I used a program called PC anywhere to access my office 
computer from any where it worked fairly well.  An I see it still available is 
anyone using it to access your host computer in your shack?  


I am open to suggestion from anyone who has a K3 up and running,  


One more thing I am disabled an right now I can get out to my shack via a 
wheelchair,  But I done know when I will be confined to my bed most of the 
time,  An before that happens I would like to get the K3 station remoted. 


Please all suggestion keep off the reflector and answer me direct at 
w0...@yahoo.com .
Thanks
Bill W0WFH
Linn, Mo

 Hi,
 
 I would like to be able to use my rig from other rooms in my house. I know 
 how to route audio through Skype and how to use Windows Remote Desktop. I use 
 both DXLab and N1MM logger. However, tuning the rig is usually not greatly 
 done via the logging software and if I want to run some special command, it 
 may not be available in the loggers.  So, what other free remote software are 
 others using for removing the K3 operations through a WAN/LAN?  No additional 
 hardware required/needed... I am assuming that I would have to disable CAT in 
 the logger and then enable CAT in that other software. What are others using? 
  I see some older tools on Elecraft's website, but not sure how good they

Re: [Elecraft] K3 - WinkeyUSB Keying Issue

[PKA]

Iain
It is true that the WK in remote configuration does decode the padle input and 
hence cannot send a character before it is finished. But this does NOT lead to 
what you mention. There is absolutely no problem in sending N6ML at any speed 
on a Server/Client set up. What You may have run into is the situation where 
the Client WK has been set to a too low speed - that will introduce some 
embarassing space insertion.

When adjusting the speed (on the Client window) you adjust the speed by which 
you key the Server WK (and the TX). The Client WK automatically is set to a 
slightly higher speed (call it the default speed). I have checked this at 
various speeds. Sending the quick brown fox jumped over the lazy dog the 
Server WK will just finish the word lazy when you have finished the whole 
sentence. It is the case at speed 15 wpm and it is the case at 30 wpm.

You can set the Client WK at any higher speed than the default (using the 
Client WK potentiometer) and in this way key more ahead of the Server WK, but 
this only advisable if you know you will not be break'ed. Setting the Server WK 
at 15 wpm I can finish the sentence when the Server just finished the word Fox. 
The Server WK keeps on with jumped over the lazy dog while I sit back and 
enjoy. However if you force the Client key to a speed below the default speed 
you will get exactly what you describe.

You are right that Remoterig does it in a different way and that one can use 
any keyer. This may well be a good reason to use that (more expensive) 
solution. I have heard many Remoterig signals and many of them produce strange 
effects, maybe when there are packet loss on the IP. I dont know if WK server 
Client setup would be any better in that situation - but I do think so. The WK 
solution will only output valid characters - or nothing.

Just to be clear: I have no interest whatsoever in the Winkeyer product - 
despite it may seem so :-)

I see what you mean. Are you sure the speed of the Client WK was the default 
value? Another point maybe that I have set for autospace, although I dont think 
that is the problem. What was the keying speed of each of the WKs with the case 
you present?

All I can say that here it works real fb. Actually similar to using the 
keyboard. The only difference is the added latency in the order of half a 
second or less. If you can not accept that, dont waste your time with WK 
remote. For me, the benefit of using a paddle is worth that additional delay.

 Hi Poul-Erik,
 
 I observed the problem, then explored the cause. I assure you it is
 real (or was at the time). Here's an attempt at depicting the problem
 graphically:
 
 https://plus.google.com/photos/103976355713671908425/albums/5988823147749984001?authkey=CNj2yKKlvoifXw
 
 I don't see any way around this other than perhaps to introduce a
 delay before sending the first character - the delay would need to be
 the difference in length between the first character and the
 longest-possible subsequent character (some prosign, I suppose - or
 perhaps a zero), since we don't know what (or how long) that character
 is until the operator has finished keying it.
 
 Setting the client to a significantly higher speed than the server
 doesn't seem practical, and still doesn't really solve the problem -
 the difference in speed would have to be huge to make a zero no longer
 than an 'E'!

Jed, I would also suspect the cable (having had some problems with one myself).

Not directly related: I have just tried connecting two winkeyers in 
Server/Client mode. It works great. I just came back from a short trip to OX 
and worked RC on internet with a 200 msec delay and it worked real nice. Used a 
WK-compatible keyer from G3ZLP at the Client end and an original Winkeyer in 
the shack at home. It is certainly an easy way to operate remotely using a

 Jed,
 
 If shorting the RCA plug that goes into the WinKeyer 'fixes' the problem, I 
 would suggest that the problem is in the WinKeyer.  The optoisolator (U1 or 
 U3) that 'closes' the key contact may have enough resistance to keep the K3 
 from keying reliably.  It would be informative to hang a DC coupled 'scope 
 probe across that WK output to see if the voltage is really going to zero 
 during keydown periods.

 Hello all:
 
 For the past several months, there are times when my Winkey won't key my
 K3. At first, it was after I'd change from SSB to CW. The WK sidetone is
 still audible, but the rig won't key. Lately, I've had it quit in the
 middle of a QSO as I'm sending. This morning, it happened when I tried to
 reply about midway through the QSO. It seems to be happening with more
 frequency.
 
 On Monday night, I did perform a reset/restore of the K3 configuration.
 
 I've been able to get things going again by disconnecting the RCA end (K3
 to WK cable) from the back of the WK and shorting out the tip/ground. I can
 then plug it back into the WK and continue. Also, it happens even with only
 5 watts output.
 
 I realize this is a odd issue, but hope someone may have had a similar
 experience or can offer some tips for diagnosing the problem.

Re: [Elecraft] Need volunteers to try an even better version of KAT500 firmware (rev. 1.63) -- more accurate initial tunes

[PKA]

Hi Wayne
I also did this and found that rev. 1.63 comes to a solution much faster than 
the previous versions - almost instantly - It is a very big improvement. It is 
very fast on almost all bands and on both my two antennas (80m loop and a 17m 
dipole, both with open feeder).

However on 17m where the dipole is resonant it is still going through a very 
long sequence (but its fast on the loop). The K3 ATU is much faster on this 
band/antenna which I don't understand.

In the process I saw something noteworthy: transmitting out of band does 
produce a carrier (!) while you hear the warning signal. It continues for as 
long as you keep the key down but will not come back on after key release. It 
does not transmit if you use the TUNE button. May be it's always been like that 
- you won't notice on CW.

[Elecraft] KAT500 autotune

[PKA]

KAT 01.58 is working nicely. But still, if Your antennas are changing impedance 
as the WX changes (which I can confirm is the case when antennas are mounted in 
or very close to trees :-) You are going to hear these sometimes lengthy 
clickety-clack. Even when making two configurations (one for dry and one for 
wet WX) You have all shades in between, so once in a while You are going to 
have the relays going crazy again. At least it happens to me.
This made me think if it might be avoided keeping in mind that the K3 ATU does 
the tuning a lot less noisy.

I think others have suggested a firmware change making autotune of KAT500 
initiate from the K3. This may be an interesting way to get rid of the 
clickety-clack of the KAT500 if done as follows when selecting TUNE on the K3 
(new mode: KAT500):
- KAT500 enter bypass (KPA enters STBY) and K3 performs the autotune
- K3 ATU config transfers to KAT500
- K3 ATU changes to BYPASS
- KAT500 changes to MANUAL
if the cables from K3 to KPA are not so good it may be that the KAT needs to 
fine tune. So a fine tune of the KAT might be a good idea.

Re: [Elecraft] KAT500 autotune

[PKA]

Yes Stephen thats true. The cable length is the cable from K3 to KPA plus KPA 
input to output (50 ohm straight through if in STBY) plus the cable KPA to KAT 
plus the KAT input to output in BYPASS (50 ohm straight through?). In my case 
it might be a total of 1.5 meter which is much on 6m but not very much on 160m. 
Still it might be a lot less relay chattering in the KAT500 even if it needs to 
include a fine tuning.

I had another idea, which unfortunately requires a big hardware change: install 
smaller and quieter relays, one in parallel with each of the bigger relays. Do 
the (low power) tuning using the small relays and then copy the relay config to 
the bigger relays and open the smaller ones. Maybe for the next generation 
KAT.

 An ingenious idea but I think there is a flaw in the argument, in that at
 the position of the K3's ATU there will be a different impedance to match
 than is the case at the KAT500's position further along the line.  Not only
 will the impedance move around the Smith Chart a bit but there is also the
 input impedance of the KPA500 to consider.  Maybe in practice all of the
 above may have a negligible effect, but I somehow doubt it.

Re: [Elecraft] Please test KPA500 rev. 1.38 if you get a chance

[PKA]

I just installed KPA rev.1.38 and don't see any difference from 1.37. Both work 
very well here (with K3 4.83 and KAT 1.58). I will report if I find anything 
not working as expected.

KAT 1.58 removed a software bug in the KAT which meant that the KAT did not 
output anything on 28MHz when the KPA was OPR, but worked OK when the KPA was 
STBY (problem only on 28 MHz). The bug was suddenly triggered by something 
unknown (to me).

I am operating RC using Teamviewer, keying with Winkeyer and using 
KAT500-Remote and KPA500-Remote, both ver. 1.0.5.0. I am quite pleased with 
both. It is in fact possible to include everything (HRD (including logbook), 
WKey, KAT, KPA and other SW used for RC with iPad or iPhone) on a single laptop 
screen.

However, I have a few suggestions for improvements of the KAT500-Remote:
- The tune button should change colour (more clearly) when Tune is activated
- An indication should show Power OFF when the power of KAT is switched OFF
- The coloured fields for SWR should change colour following the SWR
- VFWD and VRFL could include peak values ( it is a nice-to-have feature, but 
the living values are essential when working remotely with weather sensitive 
antennas)

All in all I must say both programs are very useful even as they stand. 
Congratulations Elecraft.

 Hi all,
 
 We updated the KPA500 beta firmware to revision 1.38 yesterday (from 1.37). 
 The change was minor, pertaining to initial conditions when the KPA500 is 
 used at remote locations. 
 
 If you get a chance, please load rev. 1.38 and verify that it is working well 
 for all normal operation. Once we see a few more positive reports, we'll be 
 going to production status on the K3, KPA500, and KAT500 beta firmware 
 releases.
 
 If you haven't already loaded K3 rev 4.83 and KAT500 rev 1.58, I'd encourage 
 you to do these updates as well. The difference between the new firmware and 
 previous production releases is pretty dramatic, as reported by beta testers 
 over the past several days.

Re: [Elecraft] Ham Radio Deluxe and KX3 Radio

[PKA]

Be aware that You operate CW on the K3 and KX3 using an app called K3iNetwork 
made by Mike KS7D. I have used it extensively over the last 18 months. Right 
now actually using it from EA8 :-) Mike is working on another app which uses 
the touch screen as a touch paddle. It still not working too well but I think

 DM780 does indeed allow CW (KY Cmd), which should work on the KX3 as well as
 it does on the K3.  It does this through the serial port, which also manages
 the PTT, no further hardware needed unless you want it to decode for you as

 The KX3 can be keyed using the KY command, but I do not think 
 HRD/DM780 implements that command - few applications do.
 The easiest solution is to use the K1EL Winkeyer.
 HRD/DM780 can also send CW using a serial port, but that is a different 
 port than is used for rig control, and you need something like the 'one 
 transistor keying interface' to make the RS-232 signal levels into 
 on-off switching needed to key the rig.

Re: [Elecraft] Shipping a K3

[PKA]

Please be aware, if you are from outside the US,  when sending Elecraft 
equipment for repair *including warranty repair* you will have to pay for the 
return shipping.

For European hams, Elecraft is offering the option to have faulty equipment 
repaired by a partner in Italy.
However, unlike your American ham friends, for warranty repair you will be 
requested also to pay for the return shipping - also if you choose to have the 
faulty Elecraft gear  repaired locally in Europe.
It may be that the same applies to other ham-radio manufacturers. But we got 
used to get a better service from Elecraft than from the others. Concerning 
shipping that's however not the case.

In my job I have over the years  sent professional equipment for warranty 
repair both in the US and in Canada, and I believe those companies did pay for 
the return shipping without asking.

I earlier - in this forum - have asked for a comment from Elecraft to this 
service related issue, but Elecraft decided not to comment (hopefully they will 
do now).

Re: [Elecraft] Ever had a WOW moment?

[PKA]

Despite whatever DX I have ever heard or worked, my WOW moment was when I for 
the first time heard clear, distinct echoes with a delay of 240 milliseconds 
(corresponding to almost two times round the world) on 80 meter with just 100W 
and a wire loop antenna. It turned out that the 80m signal escaped through a 
hole in the ionosphere, followed a duct along the magnetic field lines out into 
space and back to the southern hemisphere where it bounced back through the 
same duct and finally reached my loop antenna.

I have observed these ducts several times since - latest on Dec 20 this year. 
Chances are fair to hear echoes on 80m some time in the coming month around 4-6 
hours after sunset. K3 with semi QSK at 40 msec delay is perfect for this.
If you want a copy of a sound recording of these echoes drop me an e-mail 
off-line.

Re: [Elecraft] Using the K3 remote

[PKA]

Me too Rick!
Have used RC CW for 7 years with a Winkeyer as the only investment
But as you say it: there are many ways to do RC

I have a few additions though:
1) I operate exclusively CW (mostly ragchew type) and use a Winkeyer and WKDemo 
software. Works great - normally no latency issue at all (NB: people often 
confuse IP latency with the latency coming from operating through a CW buffer), 
however the Winkeyer operates thru a short buffer allowing fast BK-type CW if u 
like.
2) I use IP-Sound (instead of Skype). It has a much better sound quality for CW 
but may not offer much advantage for SSB. Works through VPN, I use Hamachi.
3) Also sometimes I use K3iNetwork (and K3iDitDah) for full RC of the K3 from 
an iPhone or  iPad -  when operating this way I use Skype as well. It's cool 
running CW QSOs from iPhone!
4) Switching ON/OFF via GSM/SMS - completely independent of the internet.

Using Teamviewer makes it easy to swap between using HRD/laptop or 
K3iNetwork/iPad/iPhone - you can even do it on-the-fly during a QSO

Emne: Re: [Elecraft] Using the K3 remote

I'm cheap.  I don't throw things away until they are beyond any reasonable use 
plus I like toys.  So here is how I run my K3 remotely:

I have an old laptop for the shack computer.  It runs HRD, has a four port 
USB-Serial cable and wifi to the home LAN.  It takes only a little power, 
doesn't cost much to run (but I'll have to upgrade it to Win7 soon).

Via HRD, I have full control of the K3 (the next version of HRD will even 
improve this).  By using a SignaLink USB for radio audio, I don't ever worry 
about OS noises being transmitted.  SLUSB=radio, OS=laptop speakers

I can run the basic K3 via HRD at home or while away (remote); even from 
another computer in the house.  BO-ring since I have the KPA500 and KAT500 as 
well.  So;

I use TeamViewer (free) to remotely control my shack laptop from another 
computer, laptop, iphone or ipad.  This allows me to also run the utility 
programs for the KPA500/KAT500 so I can switch antennas, manage the amp 
(on/off, watch temps, SWR etc) and check that the KAT500 tuning is valid 
(remember the 4 port serial cable?).  The second K3 antenna port is ALWAYS 
connected to a dummy load in case I goof; the KAT500 is my antenna switch.

I use Skype (two accounts) when running remotely and have set it to treat the 
SLUSB as its main audio device EXCEPT for anything that shouldn't go there 
(like ring tones, dialing noises etc.).  Just use it for the mike and speaker, 
no OS.

Bonus: I use the web cam on Skype video so I can 'see' the P3 panadapter 
display (or my weather station) remotely.  It's possible to make changes to the 
P3 via macros but I don't bother.

You may wonder about shack access security; by using TeamViewer to access my 
shack laptop (shack-top?) I can leave Skype NOT in autoanswer mode and answer 
my own calls, remotely.  All other inbound calls are ignored (no auto-answer).  
TeamViewer and HRD are fairly secure and I've had no issues.

In the event that there is a power failure, someone has to have physical access 
to the station to turn the K3 power back on.  I'm working on this (use an alarm 
or tickle the ACC line for now).  That someone also makes a pass through the 
house to water plants, grab the papers etc.

I don't do CW ragchew remotely as Internet latency can be an issue but since 
most of my CW Q's are call:report TU:73 and those are recorded in memories, 
there is no reason I can't DX on CW while away.  I've done digital modes 
remotely but mostly I just use the remote ability to chat with the local folks, 
while I'm away.  They can't tell if I'm local or gone unless there is wimpy 
internet (or d-d-d-d-igital-l-l-l-l artifacts) at my remote location.
I don't use VOX when the internet bandwidth is thin.

So I can be having a lazy morning in bed, be on a beach, in a forest or a 
desert watching the sun rise having my morning coffee while chatting with the 
folks on the morning net(s) or 6M repeater via a Bluetooth headset to my iPhone 
(even on 4G) or laptop (or use regular headsets into the remote laptop).  

So far, I've operated remotely from Hawaii, Alaska, the Yukon, BC, most of the 
Western States and all over CA.  Yah, the folks at home get jealous; that's 
just icing on my travel cake.  ;o)

While there are other ways to go remote, most of this was 'free' (since I owned 
it or it WAS free software) and it is pretty darned cool stuff; sometimes being 
a nerd is pretty awesome.

Merry Christmas,
Rick wa6nhc

ground service or equivalent to the continental USA and Canada. Alaska, Hawaii 
and outside U.S. and Canada actual return shipping cost paid by owner.

This is understandable if the repair service is done in USA.
However, when the warranty repair of a European customers Elecraft product is 
done by a  European based Elecraft repair service, I would find it fair that 
Elecraft would pay for returning the warranty-repaired item.

What do you think?

Re: [Elecraft] K3 Ham Radio Deluxe

[PKA]

I am using HRD 5.24 and remote access (using Teamviewer).
It works well enough for my use (100% CW)

For me, the problem with a few  buttons is just an annoyance.
But there are other shortcomings in old HRD versions. I don't know if they 
apply to the most recent versions.

1. Keying a Winkeyer is possible, but the buffer handling is very slow in 
starting up sending CW. I used it for several  years, but had a real 
eyeopener when I changed to using the WK Demo program. It is so much faster 
and works absolutely great.
Actually using HRD with its poor buffer handling for keying a Winkeyer may lead 
to the misunderstanding that the internet latency is an obstacle against using 
CW-over-IP. It generally is not.
2. RIT does not work (I just use split VFO)
3. There is no good reading of the K3 SWR. However the TX level in upper left 
corner does show the SWR well enough to let you know if you have to activate 
the ATU (also when operating on a long latency internet connection)
4. Some  buttons do not change colour when selected. Of the few I use, the 
following do not change colour: Split, Test, NR, ALT. But that's not a real 
problem.
5. The VFO-B frequency reading acts strange. It seems only to read the 
frequency when I change VFO-A value. So if I push AB and then change VFO-A it 
will change to the old VFO-A value.  As I recall it, I did not have this 
problem  on earlier versions.

Having looked on the internet for RS-232 to WiFi adapters I can find them in 
the price range from as low as 40 USD to as much as 350 USD.
I wasn't aware of the variety!
I wonder if someone in this group has any experience (good or bad) with RS-232

Re: [Elecraft] Use K3/0 in another room in my QTH?

[PKA]

You can achieve perfect audio for CW if you use IP-Sound in stead of Skype.
Skype works but the audio quality is not very good for CW.

You may need to use VPN for IP-Sound. I use Hamachi which is easily installed 
and set-up.
The audio quality for CW is comparable to being directly connected to the K3.

ADDENDUM
Although not related to K3/0 ...
I can recommend the following set-up for remote control of K3 from a client 
laptop:

Server (in shack):
Teamviewer
HRD
Winkey Demo
IP-Sound
Hamachi VPN

Client (opr pos)
Teamviewer
IP-Sound
Hamachi VPN

With these (all free) pieces of SW you can work real smooth RC. It really 
doesn't matter that it is not one piece of SW (as some might think). 
Using HRD only on the Server (as opposed to using it as Server/Client)  you 
have the logbook and audio-grabbed files etc. all collected on the shack laptop 
(server). This may be useful if you operate either from the shack or remotely. 
I recommend  using the WK Demo SW for K1EL keying of the K3. It is far superior 
to using the CW key in HRD, because the HRD keying is very slow-starting and 
also difficult to stop. WK Demo works real fast (both start and stop).  When 
set up correctly you can work real QSK type QSOs.

I recommend the following for remote control of K3 from iPhone:
Server (in shack):
Teamviewer
K3iNetwork
Skype

Client (opr pos)
Teamviewer
SServer
Skype

NB: Mike KS7D is working on an app for remote control of K3 and keying with the 
iPhone used as a paddle (similar to iDitDah).
If you are a keen CW opr and have K3 and iPhone, that should be really 
thrilling for you!

 Ron,

 You can connect the K3 and the K3/0 or another K3 using a null modem cable.
 The downside is that you do not have audio or keying capability on the 
 local K3.  If you can live with that, just connect with the null modem 
 serial cable - no network involved.
 Hold CONFIG down for 3 seconds to put the K3 (or K3/0) into terminal mode.
 At least that is how it worked when Wayne first developed the code - 
 some things may have changed since then.

[Elecraft] [K3] TX gain calibration

[PKA]

K3 ser. No 03674
MCU 4.39
Utility 1.2.12.28

I recently had to make a new TX gain calibration.  Apparently it was only 80m 
where the K3 every now and then  displayed  High Current and reduced the 
transmit power. Even when setting power to a low value (e.g. 25W) then the very 
first CW character would create an output signal 100W  and the High Current 
would briefly be displayed and the power then would be reduced.

The calibration went smooth and all is now again OK.

It might be interesting to compare the previous calibration result with the new 
one. Unfortunately I didn't save the old calibration result before making a new 
calibration and the results seem not to be automatically saved on the PC. Is 
that correct, also in more recent versions of the utility?

My main question, however, is: what could have changed over time in the K3 
which in turn makes a new calibration required? Maybe someone in this group 
could make a complete list of the factors which could potentially have changed 
and making a new calibration required.

Re: [Elecraft] Remote rig versus homebrew challenges

[PKA]

There are probably many different type of applications of remote control of a 
ham station.
Basically I distinguish between 
1) control of a truly remote station (with better antennas than what you can 
get at the operators site)
2) control of your home station when you are away from home.

Why distinguish?

 Because in case 1) you don't necessarily need a computer at the operating 
position. As others point out, it may even be an advantage to use a dedicated 
system like RemoteRig.

However, in case 2) you very often need to carry a laptop anyway, so the use of 
RemoteRig means carrying additional hardware. Even more, iIn case 2) you can do 
away with a laptop without any special programs installed for the rig control. 
You can use Logmein which you can reach with a browser. You do need e.g. Skype 
installed though.  In case 2) you can even do away with just an iPhone using 
Mike KS7D's neat app called K3iNetwork.

You probably can see I'm the typical case 2) user. I've been that for over 5 
years now with 15k remote QSOs or more.
Lately having much  fun using the iPhone - it works fine up to 24 wpm on CW 
with my fingersize :-)

If I will have to live in a place without antennas, I will become a type 1) 
user and then I will use RemoteRig and K3 (or KX3) to K3 remote control.

Hi Keith,

That is a very broad set of questions. I have successfully ran remote stations 
using computer control only for several years, but have migrated almost 
everything to the RemoteRig hardware. This brings a number of advantages and 
disadvantages, for example:


  * Advantages over traditional remote control methods:
  o Embedded device - set and forget. User can not mess-up the
interface such as they can on a PC running Windows.
  o No PC needs to be running at the remote site
  o Small size and low power consumption (2.2 watts using 13.8 volts)
  o No issue with installing and running in a rough environment such
as a mountaintop
  o High quality audio (using SIP protocol) with selectable CODEC's
  o Extremely low latency (about 20 ms). I know of users that use
RemoteRig for QSK CW at 40 WPM over the internet
  o Built-in CW keyer allowing the use of a paddle
  o Two built-in serial port servers for e.g. CAT and one other
device (e.g. rotator or amplifier)
  o Support for multiple locations (profiles) to switch between
remote station locations on the fly
  o Support for a virtual FSK COM port, and/or the operator can use
digital modes (e.g. AFSK, PSK31, etc.) by connecting an audio
cable to the control RRC box
  o When using a transceiver that has a separate control head, such
as the TS-480, or the twin concept, such as the K3 Twin (2x K3's
or a K3 + K3/0), one can use the control head or other rig at
the remote location as if the rest of the transceiver is also
local. This makes for a better user experience than being
dependent upon using only PC software for transceiver control.
  * Disadvantages over traditional remote control:
  o Cost is about $500 per set (would however save money if a PC is
not installed remotely)
  o Requires some networking knowledge to make the initial set-up,
after that essentiall plug and play
  o Cost of 2nd K3 or K3/0 if you wish to have the K3 Twin experience


As far as your problems are concerned:
- You can pass CAT over COM2 on the RRC's and just run that on your local PC, 
HRD or whatever software you wish to use.
- You can pass the rotator over COM1 on the RRC's and just run a software 
control over the internet

So yes, I believe that this will solve your problems.

-- You need to first decide if you will go the Twin route, or just
run computer control on the control side

You need to buy:
- The set of 2x RRC's
- If going the Twin route, then either a 2nd K3, or the K3/0
- The appropriate cable set depending upon the hardware configuration used

If you have any further questions, just drop me a mail.

Mitch DJ0QN

Re: [Elecraft] [OT] Radio Control via HamLog on iPhone

[PKA]

Hi Nick
I just saw your demo video and found it very interesting. I am wondering what 
is in the pigtail box, and whether what you are asking for is what interest 
there is in such a unit. 
It is quite interesting since it would make remote control  of your K3 not 
depending on a PC or laptop in the shack. So you can definitely count me as one 
who is keenly interested.

I have used HRD and worked thousands of remote controlled CW QSOs now for over 
5 years. I started using HRD in server/client mode. But since I am purely using 
CW and since the HRD server/client serial connection is very sensitive and 
keeps dropping out, I soon gave that up and started using HRD via remote 
desktop. This in combination with using Logmein for remote access has worked 
well for me for several years - and I still use it.

Recently I have tried KS7D Mike's K3iNetwork app. for iPhone with the SServer 
running on the shack PC. It still has a few bugs (connection may drop while the 
server still thinks its OK, so you need to reset SServer, also sending macro 
commands to the K3 means that the K3iNetwork app. needs restart and a few other 
inconveniencies). But it certainly works fine and I have made a lot of QSOs 
with iPhone over 3G network to the SServer/K3 (even worked HK0NA that way!)

I still do not fully understand how your set up would be. Is it correct, that I 
need 1) to run hamlog on a portable device (PC or iPhone) and 2) connect via 
internet to the wireless router in shack. How then is the connection in the 
shack from the wireless router with the pigtail to the K3? The pigtail box 
connects directly to the wireless router?

Sorry if my questions are silly!

Vy 73 and maybe cu on air remote to remote on CW Nick!

Hello Everyone,
Over the years that HamLog (http://goo.gl/BMFzM) has been available on the 
various mobile platforms out there, I've had several users ask me for a way to 
get radio information into the app automatically, both at home and/or out in 
the field, portable, dxpeditions, etc.  In the past few weeks I've put 
something together that allows HamLog to talk to radios for both command  
control and state retrieval.  Below is a link to a demo of it working with an 
iPad and a K3.  The video should answer a lot of the questions you might have.  
This is all entirely beta at the moment so it might not look like this in the 
first release.

Demo Video (about 9 minutes):
http://goo.gl/N8JK7

Take a look and let me know what you think!  If you're interested in having 
one, please visit the following URL and enter your call sign and email address. 
 There is no obligation and I'm not asking for any type of deposit; I just need 
to gauge the demand for the initial run.

Re: [Elecraft] K3 and K2 simultaneous on serial to USB cables tocomputer

[PKA]

In the KPA100 Manual there is a warning not to use standard RS-232 cables 
between the K2 SIO and a PC (only pins 2, 3 and 5 are normally connected)
Would it not be a similar problem using a serial to USB adapter?

Ron -

You might consider getting a 4 port USB to Serial adapter. I have my IC-7000, 
K2, and W1 wattmeter connected to one and all three are accessbile, each with 
its own com port assignment.

The one I purchased is based on the FTDI chipset, like the Elecraft KUSB 
adapter, and was abt $44 from Amazon. Search for:

Re: [Elecraft] Wireless Remote for the K3

[PKA]

It is interesting to see a whole new type of remote control of K3 (and other 
radios?) develop.
I have now for 3 months been playing with the iK3network and an iPhone 4 
connected either on 3G networks or on WiFi hot spots  and regularly work QSOs 
on CW with up to 24 wpm.
The app still has a few bugs and also has room for improvements, but Mike KS7D 
is working on it.

I just worked HK0NA on 20CW using the iPhone/3G network  from a car (K3/100 and 
dipole!!) You can set the split using macros.
So it works also for pile ups!! It is easy to make accurate timing.

It is not as quickly set up, as when you are in front of the rig, but it is 
feasible.

Re: [Elecraft] Remote Control of K3 with iPhone/iDevice

[PKA]

OK about USB and LSB - who cares about phone anyway :-)
I have been playing with it a while and am amazed how well it works.

I have connected from my home network and from the outside, using the IP 
address.
I do something similar when connecting e.g. HRD from the outside.
I had an account on DynDNS some time ago so I didnt have to worry about my 
dynamic IP address, but that service which was free has now stopped.
If I use DynDNS or another similar service, can I then enter an URL like 
oz4un.dyndns.org (which was the one I used to have)as IP address?

The selected frequency steps of 1, 10 and 1000 Hz may be OK for some.
I would prefer 10, 100 and 1000 if only three choices are available.
Or maybe the Fine knob could be changing between the two sets?

Again - my respect for a fine piece of SW!

 The apps use two different approaches to communicate with the K3

 K3iNetwork uses your local WiFi network and PC/Mac to communicate

 the K3 line out can be streamed to the iDevice with a third party

 Both apps will work with the P3.

Re: [Elecraft] Remote Control of K3 with iPhone/iDevice

[PKA]

Hi Mike
The frequency buttons are the most important i think. Maybe for digi modes they 
need 1 Hz steps, and it also necessary for using APF, but I use 100 Hz steps a 
lot more than 1 Hz.

I have used macros UP8 and DN8 and discovered that the program stops after 
using these macros. Also use AG macro to adjust audio gain and KS for CW speed 
control - and also these make the program stop as far as I remember.

By the way, can I link two or more macro's in one (e.g. ks020;ag050)?

[Elecraft] Harmonics from K3

[PKA]

I have been measuring the level of harmonic spurious from my K3 #3674 and came 
up with some interesting results.
 
I measured with the K3 connected to a dummy load and to my antennas (loop for 
80-40-30 and 17m dipole for higher bands, both antennas fed by 450 ohm feeder 
and Elecraft 4:1 baluns). Since I have one of the older baluns with just one 
ferrite core and one with two cores, I measured on each antenna with each of 
the baluns.

In all measurements I used the K3 ATU and the SWR was 1 bar segment

I used a RohdeSchwarz FSH8 portable Spectrum Analyzer using a short wire in 
the input connector center pin  to pick up the signal from the antennas. The 
analyzer was in my shack, next to the rig. But since I also used the pick-up 
antenna to measure the leaking signal from the dummy load (and the harmonics 
were all very low) the higher level harmonics measured when connected to the 
antenna supposedly did not come from stray signals in the shack.

So, what did I see with K3 transmitting 100W?
1,8 38 dB 
3,5 37
7   55
10  43
14  40 (2nd harm)
18  44
21  53
24  49
28  59
This seems pretty good to me.

dipole (20-10)

14  16 (2nd harm), 3rd harm at 30 dB
18  29
21  28
24  28

Especially the 14 MHz value was a surprise, but generally much higher harmonics 
on 30-10m than on the dummy load

14  17 (2nd harm)
18  35

24  36
28  42
The 14 MHz value still pretty bad and the high bands much better now with 
2-core balun. Low bands some worse and some better with 1-core balun!

Finally - assuming that some of the harmonics might origin from non-linearities 
in the balun core - I measured on 14 MHz with the 2-core balun at different 
power levels:
14 MHz, 2-core balun and dipole antenna
100W18 dB
80  17
60  16
40  16
20  18
10  21
5   21
It seems that the power value has very little influence on the harmonic level, 
so my theory of harmonics being created in the balun may not be correct.
When the ATU shows SWR ~1 does it mean that the current waveform in the PA 
transistors are independent of whether the load is a dummy load (and the ATU 
practically bypasses) or the load is a complex impedance requiring some L and C 
to reach 50 ohms?

Now I have the following questions:
1) is my K3#3674 specifically having a problem concerning harmonics on 14 MHz 
or would I measure the same on any other K3
2) what is the reason that I measure much higher harmonic levels when connected 
to the antenna than on dummy load?
3) when the ATU shows SWR ~1 does it mean that the current waveform in the PA 
transistors is independent of whether the load is a dummy load (and the ATU 
practically bypasses) or the load is a complex impedance requiring some L and C 
to reach 50 ohms?
4) have I overlooked some fundamental measurement error in using a small piece 
(3 cm) of wire to pick up the RF signals?

Re: [Elecraft] Harmonics from K3

[PKA]

 
Hi Jack
Thanks a lot for your valuable feed-back.
Yes you are correct that there are some assumptions.
The Spectrum Analyzer is very flat over the spectrum I have been checking - 
thats a fact.
I assumed that a small piece of wire would be fairly omnidirectional - and thus 
have the same gain - on these low frequencies. I still think that is true, butI 
have however not taken into account that the short wire will have very 
different impedance on the fundamental and harmonic frequencies. This may be an 
important error source.

Yes I am indeed in the near field of the antenna, and this may be a source of 
error too. This I can verify, because the Spectrum Analyzer may run on 
batteries and I can operate the K3 with my iPhone (or a small laptop) so I can 
easily measure in the far field. I need to think about how to make a proper 
measurement antenna though.

I dont think pick-up directly from the K3 due to imperfect shielding is the 
cause, since it then also should be present on the measurements on the dummy 
load.

But, al this said, I don't think it explains why the measurements are so 
markedly different on 14 MHz compared to the other bands. Thatr is my main 
worry.
The question remains whether this is specific to my K3 or to something else 
locally.

Emne: Re: [Elecraft] Harmonics from K3

Poul-Erik:

You have an implicit assumption that the spectrum analyzer to transmit antenna 
has a flat response with respect to frequency.

That's unlikely to be the case.

Another assumption is that the spectrum analyzer antenna is in the far field 
of the antenna. This is also unlikely to be the case.

And another is that the K3 itself does not radiate due to imperfect shielding 
which may be a problem when the pickup antenna is close to the K3.

The normal method to measure harmonic suppression is to use either a power 
attenuator, such as 30 dB attenuation rated at 100 watts, so that the spectrum 
analyzer only detects signals from the transmitter. Or, if a suitable power 
attenuator is not available, a standard dummy load and a resistive tap or a 
directional coupler of known frequency characteristics can be used to obtain a 
low level signal sample that does not vary with frequency.

With respect to measuring radiated harmonics, the most accurate method is to 
locate the measuring equipment sufficiently far from the transmit antenna such 
that the signal is far field. 10x the transmitting wavelength is a safe number, 
but a somewhat shorter distance may be OK.  
The spectrum analyzer or field strength meter uses an antenna with a known 
antenna factor at the fundamental frequency and all the harmonics so that the 
actual radiated field strength can be computed and from that the harmonic 
level. Since the transmitting antenna almost certainly has directional 
characteristics -- particularly at harmonic frequencies -- several sets of 
measurements should be made at varying azimuths from the transmitting antenna.

So, to make these measurements accurately in the case of radiated harmonics is 
a non-trivial undertaking.

It's a great new use of the iPhone! For the audio I use Skype which works OK, 
but it is not best suited for CW.

Wow. Steve Jobs would have been proud. Just pointed out to the XYL I can sit in

This is just cool.

Thanks, Mike.

  K3iNetwork uses your local WiFi network and PC/Mac to communicate 
  with the K3. In this case you need to have your K3 tethered to your 
  PC or Mac via an RS232 cable. The advantage here is that sound from 
  the K3 line out can be streamed to the iDevice with a third party 
  app such as Airfoil.
 
  Both apps will work with the P3.
 
  I have used these apps to carry on CW and data QSOs with other

Re: [Elecraft] K3 antenna tuner question

Thats an interesting observation Guy. Anybody out there who can explain?
Now, the ATU process is done at low power, so there should be some other 
explanation why the K3 ATU fails to stop at the best LC combination.

Having a lot of water around means that the antenna impedance changes with the 
power level.  I have seen this many times here on 160 with wet leaves very 
close to wires, and sometimes touching.  I can watch the SWR vary under a 
steady 1500 watts, something not seen or far less obvious at 5 watts.

No attempt at explanation.

A quick way to find the best LC combinations manually is to tune them

'key down' to tune an external ATU.
The KAT3 will use a much lower power than that for it's internal tuner I 
believe.

Re: [Elecraft] key dot weight

[PKA]

Hi Kevin
Tnx a million for your valuable response. I don't know if there is a definition 
of a 50% weight ratio on a shaped waveform, but I surely know what the 
displayed waveform sounds like! And it looks just like what I had expected.

I am a little embarassed on behalf of Elecraft that this was not readily 
available info. After all, most buyers of Elecraft devices probably are keen CW 
operators and my guess is that a lot of us have bought Elecraft exactly for a 
reason: to be sure to have the best CW rig on the market. It still is pretty 
good, but the internal keyer problem is a flaw.

Therefore, Elecraft, how about a modification which enables the internal K2 
keyer actually providing 50% weight.

Paul,
I don't know exactly how the weight is defined for a shaped wave form.
So to answer your question for my K2, I put the wave form from my K2 serial 
number 5235 when set at 40 wpm and weight 0.90 and at 1.10 in the files:
http://fermi.la.asu.edu/w9cf/k2/40wpm_090wt.jpg
and
http://fermi.la.asu.edu/w9cf/k2/40wpm_110wt.jpg
40 wpm should take 60 milliseconds between dots.  You can see that, at the 
default weight of 1.10, it takes something like 67 milliseconds between dots 
and is quite heavy.  At 0.90 the time between dots is about 60 milliseconds, 
but it looks to me to be a weight of at least 1.0 and probably more.

I recorded these with my K2 set at minimum power into a dummy load, and used a 
separate receiver to the sound card on my laptop (the receiver was my ATS-4a 
which has no AGC).

I hope this helps.

73 Kevin w9cf

Re: [Elecraft] key dot weight

[PKA]

I have raised the problem of keying weight on the K2 several times earlier - 
but I never got an answer.
So I'll try again.

The dot weight ratio on my K2 is unable to reach 50% on my K2. Even with weight 
set to 90% (0,90) the weight is too heavy. Fortunately a somewhat higher weight 
sounds better than a somewhat low weight, so maybe thats the reason why there 
is not much discussion about K2 internal keyer. But for higher speeds a correct 
weight is important. For my taste the keyer is not acceptable and I soon gave 
up using it entirely.

Is this a specific problem for my K2 or is it a generic issue? What is the 
actual measured weight range in Elecraft labs?

I found the K3 keyer much better ;-)

  John,

What keying speed were you using?

Key weighting changes the ratio between a dot and an intervening space.  It 
is not likely that you will notice a difference at speeds below 25 or 30 WPM.  
Below those speeds, I suggest leaving the ratio at 1.00.
If you are doing higher speeds, you might want to increase the weighting a bit 
if your keying sounds light - I know this is a perception issue, so there are 
no real answers to what is right.  A lot of the answer depends on the 
particular operator's experience and how he likes to listen to CW at higher 
speeds.

 higher weight sounds better than a somewhat low weight, so maybe thats the 
 reason why there is not much discussion about K2 internal keyer. But for 
 higher speeds a correct weight is important. For my taste the keyer is not 
 acceptable and I soon gave up using it entirely.

 Is this a specific problem for my K2 or is it a generic issue? What is the 
 actual measured weight range in Elecraft labs?

 I found the K3 keyer much better ;-)

 Emne: Re: [Elecraft] key dot weight

 John,

 What keying speed were you using?

 Key weighting changes the ratio between a dot and an intervening space.  
 It is not likely that you will notice a difference at speeds below 25 or 30 
 WPM.  Below those speeds, I suggest leaving the ratio at 1.00.
 If you are doing higher speeds, you might want to increase the weighting a 
 bit if your keying sounds light - I know this is a perception issue, so 
 there are no real answers to what is right.  A lot of the answer depends on 
 the particular operator's experience and how he likes to listen to CW at 
 higher speeds.

 Don W3FPR

Re: [Elecraft] [K3] Auto-Tuner Recommendations...

[PKA]

The K3 ATU is not always stopping at the optimum LC combination.

However, it does not stop too far off. In some cases (rainy weather) I have 
noticed that it stops at SWR=1,4 even when there is an LC combination giving 
SWR=1,0.
I don't see it as a big problem. But it is annoying when using remote control, 
if the RC program is not showing SWR very well (this may be the case when using 
HRD over remote desktop)

I really prefer the LDG tuners over the MFJ.  I have several and they all work 
well. I also have an MFJ tuner so my comparison is based on side-by-side 
operation.  Right now, I have the AT-600Pro in line with the K3/100 and the the 
Ameritron ALS-600. I have very good results running into a 160 feet doublet fed 
with good quality 300 ohm twinlead.  
I have a DX Engineering 1:1 current balun inline after the tuner.  This is a 
very effective setup.

Re: [Elecraft] Remote control of K3

[PKA]

There are many possible solutions for RC today.
What I describe here has one specific advantage: it is very cheap to implement.

I am using HRD. My preferred opr mode is CW so I had to buy a winkeyer.
I use Logmein.com for remote access to the shack. Since my IP address is 
dynamic, I am using DynDNS.com.
Both services exist in a free-of-charge version which is adequate for my 
purpose.

I did operate with HRD on the remote PC in a client-server configuration for 
the first few years. It gives a faster responding control over the K3, but the 
serial link which is needed for CW is very sensible to link quality and drops 
out from time to time - very annoying, so I decided to use a remote desktop 
solution.

The solution with HRD-over-Logmein has the following advantages:
- essentially free of charge (must have a winkeyer, must have a shack PC)
- works CW (and other modes)
- can be operated from any PC (does not need to have any special programs 
installed except for Skype)
- the log is always on the same PC (using HRD log)
- it operates fast enough to work DX pile-ups where timing is essential

NB: I am now using an USB media controller (dial knob) from Griffin on the 
remote, so I can dial over the band in the same way as in front of the K3. This 
is somewhat nicer than using the mouse or arrow-keys.

I have been using the N4PY Pegasus Plus software package for some time now with 
great success with the K3, transverters, amplifiers, and rotor ( www.n4py.com). 
He has a client server architecture that lets you run the software without 
needing to expend the bandwidth required by a remote desktop solution. My 
client is set up to interface directly with the N1MM logging program as well. 
The documentation shows it will control a Hy-Gain rotor and the LP-100, not 
sure about the Alpha. 

One caution if you are using a USB adapter, the Prolific USB adapter can get 
overloaded and throw out bogus information from time to time, the FTDI based 
adapters appear more stable.

[Elecraft] LDEs on 80m

[PKA]

I think there is a good chance of observing Long Delayed Echoes on 80m these 
days.
 
I noticed very strong echoes yesterday 6 Jan 2011 at around 19:50 UTC (approx. 
5 hrs after local sunset) on 3523 kHz but just a couple of times during a 5 
minute period. I think I switched ON too late and missed the better part of a 
longer period. The echoes were strong and quite similar to those I recorded in 
January 2009 (delay 237 milliseconds and strongest around 19:30 UTC, about 
4h30m after local sunset).
 
If you operate K2 or K3 with Semi QSK delay of 0,04 sec you will notice this 
kind of echoes immediately.
 
Good luck!
OZ4UN, Poul-Erik

Re: [Elecraft] KAT3 don't tune

[PKA]

 
Hi
I have the same problem, but with a twist to it. I even got Elecraft to send me 
a replacement KAT3, but it did not help anything.

By chance I tried one of the older configurations (call it config B) and then 
all of a sudden the ATU worked excellent (able to tune a 80m loop and a 17m 
dipole on all bands from 80m thru 10m ... Yes even the dipole!... Both antennas 
use 450 ohm ladder and 4:1 baluns. By the way, now the ATU works better than 
ever before. It never before was able to tune the 17m dipole on 30m, 40m or 80m 
- but now it is!

BUT now with config B something weird happens when the rig is switched ON. The 
TX symbol flashes like in test mode, but there is no audio and the TX LED goes 
on when keyed. I have not found any other way to get out of that mode than to 
make the EE Init reset. Having done the EE Init I can only make the rig see 
the KPA3 and the KAT3 by loading a config file.

If I try manually to use CONFIG to select ATU Auto I hear relays clicking, when 
selecting KPA3 I dont hear any fans going in the fan test and leaving the KPA3 
in norm and leaving the CONFIG it seems that the rig doesn't see either KAT3 or 
KPA3. As soon as I load config B all works again and the ATU too ... Until next 
time I switch ON the rig. Then it needs another EE Init and config load.

If I load config A the ATU doesn't work, but now the rig can be switched OFF 
and ON without problems.

I can not see any difference between config A and B and I don't know why the 
rig configuration should influence the functioning of the ATU. Also my K2 works 
fb with its ATU. So the problem is not in the hardware or antenna, but 
something else.

Elecraft is looking into it.

Hello,

I have worked CQWW SSB this weekend and noted that kat3 don't tune correctly.

Many times after tuning SWR is 1.2 or 1.3 even there is no more swr on antenna.

I have dipole on 160 meter and swr is under 3 to1 on band, but kat3 try and try 
long time and leave it 1.8 if at all.

My K2 with KAT100 work correctly with these same antennas.

What is the problem?

[Elecraft] K3 #3674 needs EE Init after each power OFF/ON *** Update

[PKA]

Wonder if anyone else has seen this odd K3 behaviour and may be able to help me 
solving the following problem.
 
K3 with ATU and KPA
K3 loaded with most recent firmware (MCU 4.12, FPF 1.13, DSP1 2.60).
I have repeated the firmware download a couple of times, but it did not solve 
the problem described below.
 
Every time the K3 is powered ON (using the K3 pwr switch)  it comes up in 
unexpected state where
- the LCD indicator TX is blinking (as if TX is in test mode)
- the TX LED lights red when keying (CW)
- there is no sidetone when keying
- the power indicates 0 and there is no output (verified on sep. RX)
 
Restoring saved K3 config. doesn't help. But..
When leaving the K3 powered ON but just idling for a long time, it can be keyed 
again. After 15 mins it still is in the strange state but after 30 mins it is 
normal again.
 
Whenever it is in this state with blinking LCD TX indicator it can be recovered 
performing the EE INIT (Manual p.65), upon which the TX led stops blinking and 
the K3 can be keyed again. It just needs the proper saved K3 config file - and 
it's a tedious way to start-up the rig ;-)
 
OZ4UN
Poul-Erik
 
- - - - - - -
Update
 
After this was mailed I was unable to get the K3 to get back to normal state by 
just leaving it.
Reload of 4.12 f/w did not work. The only way to get RF out of the box was to 
execute EE INIT.
 
Then I loaded older f/w from the Elecraft FTP server (MCU 4.05, DSP 2.58 and 
FPF 1.10) and got that to work.
After that I re-loaded the recent firmware (MCU 4.12, FPF 1.13, DSP1 2.60) and 
since then it works again - no need for FF INIT.
 
Now, however, the ATU can no longer obtain 1,0 SWR on many bands where it used 
to obtain 1,0 (with my loop and dipole antennas).
Is this a matter of calibrations no longer being valid?
 
Are you supposed to repeat the calibrations after loading new firmware?

Re: [Elecraft] K3 CW keyer issues

My K2 internal keyer can not achieve a correct weight (50% duty cycle of dots). 
The minimum setting of 90 is still too heavy, except for at low speeds, where 
its acceptable.
Anyone else having observed this, or is this just my K2?

[Elecraft] K3 chirp

[PKA]

Just to close this subject maybe.

In addition to the chirp I found on my K3 on 3526 kHz I was told by others 
(Bruce N1LN) that they had found chirp on 14030.5 kHz. Bruce cured it by adding 
a resistor+capacitor to the Synth Board and load a specific f/w file and Bruce 
praises the support from Elecraft!

I checked mine, and indeed I also found chirp in a 400 Hz range around 14030.6 
kHz. It was even worse than the 80m chirp and over a much wider bandwidth - it 
sounded real bad.

I then first soldered in a 55 ohm resistor on the KSYN3 board across R20 (as I 
was originally told to try by Gary). It took away the chirp on 80m but did not 
improve much on 20m.

I then received the specific f/w file hfpf0108.hex from Elecraft and also the 
suggestion to solder in a resistor + capacitor combo to terminate the xtal 
filter on KSYN3. I decided to try the f/w upgrade first without this 
termination, since I was not too happy with soldering on the KSYN3 board. I 
placed the hex-file in the directory with the (latest) firmware files and 
loaded all new files into the K3 and ran the VCO MD Cal. This eliminated the 
20m chirp problem.

I have not yet checked every band and every frequency - which requires about 
6000 measurements where you have to tune both the K3 and a separate rcvr ;-)

The solution of this problem gives me good reason to also praise Elecraft 
support!

[Elecraft] Chirp on K3

[PKA]

This is only interesting for users of CW on the K3.

You might want to check and see if your K3 - like mine #3674 with 3.68 firmware 
- produces a badly chirping signal when the VFO is set to a frequency in a very 
narrow range of 3525.970 to 3526.030 kHz while the rcvr is using 400 Hz x-tal 
filter (in my case FL3). Be aware that TX must be set to use FL1. You need to 
check for chirp on a monitoring rcvr.

It was found by pure coincidence during a QSO and it was quite embarassing to 
get that kind of report when using a rig like K3. It has nothing to do with RF 
level, RFI or poor PSU regulation.

Several others have reported to me, that they don't observe this problem on 
their K3s. So maybe you are just as lucky - if it is a question of luck ;-)

Elecraft have (quickly!) responded that they discovered it not long ago and 
suggest thast I solder in a 51-55 ohm resistor across R20 on the main Synth 
board. I haven't done this yet, but will report here when I have done so.

I don't know if the chirp only applies to this particular combination of VFO 
frequency and x-tal filter. Anyone else having relevant info please post here.
