Yes, that was the problem when it happened to me.  It was a cable problem 
that was inadvertently closing the key in (PA Key) input on the back of 
the KPA500.  Clearing that up restored normal operation.

Hi Barry,

There is an asterisk that appears on the left side of the KPA500 display
whenever the key out signal from your transmitter is present. You should not
see the asterisk when you are receiving. If you are then is it possible that
you are using the key out signal to operate some other device in addition to
the KPA500?

Re: [Elecraft] KPA500 Issue

2015-01-30 Thread Mike K2MK
Hi Barry,

While your experience suggests that a transistor switch will probably save
the day I also wonder if the problem is the result of the absence or
presence of a pull-up resistor or perhaps a floating common connection
between the rig and amp. Maybe a resistor in the plug would help. I suppose
there is some way to check this out.

Re: [Elecraft] Separate Receiving Antenna

2015-01-30 Thread Vic Rosenthal
I'm using a Pixel Loop as a receiving antenna to supplement my main t/r 
antenna, which is an R8 vertical. The only 'garden' I have is a rooftop about 
35 m above ground. The antenna is about 6 m from the vertical and definitely 
has a better s/n ratio. I use it on HF bands, sometimes by itself and sometimes 
for diversity reception with the K3's subreceiver. 
It isn't a panacea for noise problems but definitely helps. The diversity mode 
is also a big help despite the small separation between antennas. The Pixel 
Loop comes with a device that makes it possible to 'key' it along with the 
transmitter in order to protect the receiver. I am using this successfully with 
QSK at 1.2 kW output. The relay is noisy but fast enough at reasonable speeds.

Sounds like bad PIN DIODE situation, but I'll let those who are more

 I switch back to Stby and the received signals return to normal.

Just for reference, on six meters, using WSJT10 for FSK441 MS, I see one

Re: [Elecraft] KPA500 Issue

2015-01-30 Thread Barry Simpson
Good morning to those who responded to me on the Elecraft reflector. Here
is the interim outcome.

I did not mention that the problem arose after connecting my brand new
(yesterday) TS590SG to the KPA500.  The TS590SG has different linear
switching facilities from the TS590S in that there is now provision for
solid state switching to avoid a clicking relay. I was using the solid
state switching set up. I use the same set up with my TS990S and that works
perfectly with the KPA500.

I checked and resoldered the connecting cable and then I interchanged the
cable I use with the TS990S as the Din pin connections are identitical with
the TS590SG. The outcome was exactly the same with the loss of received
signals when the KPA500 is switched to Oper and the little asterisk appears
on the left side of the display. However, the set up still keys the KPA500
perfectly.

I then changed over to the TS990S and with that rig, the KPA500 works
perfectly with the solid state switching.

The conclusion is therefore that from an initial OK position in Stby and
Oper as soon as the first character is keyed, the solid state switch in the
TS590SG hangs resulting in the KPA500 being permanently in the transmit
state. The situation only clears when rig and amp are turned off, the Din
plug is removed from the TS590SG and reinserted and both are turned back
on. I can then switch the amp back to Oper and all is fine until the very
first morse character when it all happens again.  So as it stands, there
appears to be incompatibility between the TS590SG solid state amp switch
and KPA500.

As an interim measure, I have rewired the Din plug to use the noisy relay
for the amp control and that works fine. The TS590SG does output 12V to the
solid state switching pin in certain configurations as did the TS590S. I
had a TS590S and I wired a single transistor solid state switch inside the
Din plug and that worked perfectly so I am going to do the same again,
which should solve the issue. Unfortunately, I gave away the TS590S cable I
had made up to the guy I sold the TS590S to. I never got the very bad spike
issue fixed but the buyer did not mind as he doesn't use a linear.

It really is a pity as I thought that the new linear switching circuitry in
the TS590SG was a real step forward but it is not to be, at least not with
the KPA500.

For information and to avoid others having a similar head scratching issue,
I am copying this to the TS590 list as well. As a final point, I can
confirm that the TS590SG has no power spike issue whatsoever and the
average audio level in SSB seems much improved from the TS590S.

Once I have wired and implemented the transistor switch, I will report back
with the result.

Re: [Elecraft] SVGA NB doesn't always start latest beta f/ware

2015-01-30 Thread Stephen Prior
Hi Jim,

I can't have explained myself very well.  The NB is working (level 10) on
the P3 but on the VGA output the NB on state is not remembered on switch
off.  So if I turn the P3 off and then on again,  the NB works fine on the
P3's own display,  but to make it work on the external monitor I have to
turn the NB off then on again.  Reference to NB here is solely the P3.

Hope that makes sense.  I have been using the NB on the P3's screen for
some time now, but it is only the latest beta I think that extends this
functionality to the P3's VGA output, and that is the version I'm running.

 There are two menu functions associated with the P3 NB. One is the switch,
 the other is NB Level (or whatever it is called). If you're going to use
 the P3 NB, you need both on soft keys. First turn the NB on, then select NB
 Level and tweak it for best noise removal.

Re: [Elecraft] K3 USB--Serial Names OT, Kinda

Yep, both of ‘em are there in the Device Manager. The K3 is Com1 (not connected

Unfortunately, neither of them show the nice human-friendly names as I’d hoped 
they would. And, Fusion’s name doesn’t help, either.  Clicking each of the two 
USB icons  on the Fusion toolbar simply shows “Future Devices FT232R USB UART”. 
I knew that the KX3 is COM3, as I use LP Bridge and it shows the COM port the 
radio is connected to. Oh well, would have been nice to see the human names, 
but I guess the Microsoft folks didn’t think it was necessary.

 Looking for some help identifying the USB—Serial adapter names on Windows

 USB—Serial adapter from Elecraft. These USB guys plug into my iMac. I run 
 the K3 on the Mac side of the machine, and the KX3 under VMWare Fusion and 
 Windows 8.1 on “the other side”. On the Mac side I use MacLogger DX (MLDX), 
 FLDIGI, and WSJT-X. When I configure the radio connection, MLDX knows the 
 “names” of each adapter. the one for the K3 is A8003Ssu and the KX3’s 
 adapter is A501XNHZ. On the Mac side, it is easy to determine which adapter 
 is associated with which radio. 
 
 However, on the Windows side, it is not an easy matter at all. Nowhere can I 
 find any place where it shows the names of these two adapters. And the 
 reason why it is a problem is thus: If the K3 is not “connected” to either 
 MLDX, or WSJT-X, or FLDIGI on the Mac side and I bring up Windows, I often 
 get both adapters available to me under Fusion. If I attach the wrong one to 
 my apps on the Windows side, things are ugly and take a while to correct.
 
 Is there some way, either with Windows itself, or with VMWare Fusion to see 
 these device names?

Try a K9AY for 40/80/160 or maybe a 5' x 5' passive magnetic loop for

Dear Elecrafters,

I have a very small and odd shaped garden in which to play Ham Radio. I have
a K3 (and a K2 and... ), I run QRP CW and I was wondering if anyone had
experience of using active loop antennas as receiving antennas to lower the
noise floor. I was looking at Wellbrook's Website this afternoon, and I see
that their loops get good reviews on EHam. I was wondering what experience
you guys might have with these and similar antennas.

[Elecraft] SVGA NB doesn't always start latest beta f/ware

2015-01-30 Thread Stephen Prior
Using the just-released beta firmware I am finding that on switch on,
although the P3's NB is engaged the SVGA screen still shows pulses (in this
case from an electric fence).  Turning the NB off and then on via the P3's
menu restores functionality.  This is the case on every band I have tried.
No big deal, but sounds like a little bug to me.

Re: [Elecraft] OT: Ed Muns - W0YK

Ken and all,

Forget about Ed's prowess in ham radio!  Let's talk about something really 
important--like those wines he makes, for example!!!  Just kidding!  Ed's 
accomplishments are almost legendary.


I don't know Ed personally, though, and I wasn't aware of his involvement in 
the wine industry.  When I read that I thought this guy really has his 
priorities right!  Hi.  I couldn't help but reminisce about another old ham 
friend of mine from some 40 years back--Em Brakensiek, WA6OCT. 
Unfortunately, I lost contact with Em when he had to move around and into 
assisted care facilities, but we used to talk almost daily.  I'm sure he is 
SK now, and probably has been for some time.  Anyway, Em was also a wine 
maker, but at the other end of the spectrum from Ed.  Em made his own stuff, 
and was only somewhat proud of it.  He also ran a gift shop/printing shop 
combination, and so he printed up his own private brand labels for his 
homebrewed wine.  Being a very self deprecating fellow, the name he chose 
was Chateau Garbage' , pronounced, of course, with a nice French flavor on 
the last syllable.  What a guy!  I miss him.

Re: [Elecraft] Separate Receiving Antenna

2015-01-30 Thread Mike K2MK
Hi Paul,

A lot of K3 owners are using the Pixel Technologies loop antenna. I'm
pleased with mine in comparison to my SteppIR vertical antenna on 80 and 40
meters. On 160 meters I have a relatively quiet dipole but I find the loop
beneficial when used with the K3 sub receiver as a diversity antenna.

The company has changed names and the old links for the antenna don't seem
to work anymore. This link seems ok.

[Elecraft] mono plug in stereo speaker jack

My brand new K3 kit came with a flyer warning not to use mono plug UNLESS
you disable the right channel amp. Otherwise it could be damaged.

You set SPKRS config entry to 1 to disable right channel amp.

Re: [Elecraft] (K3) Alexloop Antenna

2015-01-30 Thread Fred Jensen
I've had an Alex Loop for about 2 years now, it replaced my Buddipole 
[about the same cost].  You can build your own mag loop for a lot less 
than the Alex but I wanted the cool carry case and had the $$ from the 
BP sale. :-))  I use the loop when activating a SOTA summit and general 
field operating, usually with my K2/10.


My Alex easily works as well or discernibly better than the BP ever did. 
 It is very narrow BW, and tuning it on 40 requires a steady hand and 
care.  It's less touchy on 30 and just fine on 20 and up.


I have mine on a light-weight tripod I found at Home Depot with a Rain 
Bird sprinkler on top.  I cut 9 inch piece of 1/2 gray PVC nipple with 
threads on one end and screw it into the tripod.  The hollow Alex handle 
fits down over the PVC.  I finally filed some shallow slots in the PVC 
to keep things stable in wind.


I set up next to the tripod and can reach up and tune the loop with one 
hand.  There is one gotcha with loops like this:  It is a resonant 
transformer.  At resonance, your SWR will be 1:1 and you'll make Q's. 
If you get it close with the knob and then let the ATU [if you have 
it] match it, you will have created a very well shielded dummy load and 
you'll make no Q's.  So, bypass the ATU and get 1:1 with the little knob 
on the capacitor.  You can't QSY more than maybe 5 KHz on 40 without 
tweaking the capacitor.  BW gets larger on 20 and up.


It is mildly bi-directional in the plane of the loop but the lobes are 
quite broad.  There are two very sharp, fairly deep nulls orthogonal to 
the loop plane which can sometimes help reduce noise or QRM.  It is 
essentially insensitive to ground, and doesn't really care how high it 
is, a tremendous advantage in the field over E-field antennas.


Pay attention to the power limits.  Because it is resonant and small in 
terms of electrical degrees, RF voltages can get quite high.  It's 
definitely a QRP antenna.


Hope this helps,

I'm using a Pixel Loop as a receiving antenna to supplement my main t/r 
antenna, which is an R8 vertical. The only 'garden' I have is a rooftop about 
35 m above ground. The antenna is about 6 m from the vertical and definitely 
has a better s/n ratio. I use it on HF bands, sometimes by itself and sometimes 
for diversity reception with the K3's subreceiver.
It isn't a panacea for noise problems but definitely helps. The diversity mode 
is also a big help despite the small separation between antennas. The Pixel 
Loop comes with a device that makes it possible to 'key' it along with the 
transmitter in order to protect the receiver. I am using this successfully with 
QSK at 1.2 kW output. The relay is noisy but fast enough at reasonable speeds.

That *ASS-U-MEs* that the person hooking up and configuring the AFSK
knows what they are doing.  Given the number to particularly gross
AFSK signals on the air today, that assumption is not a good one.

The manufacturer of one inexpensive amateur sound interface even
instructs its users to run the Windows sliders at maximum (it needs
that because its internal VOX is not sensitive enough otherwise) but
that drives the poorly filtered and unregulated DAC into distortion.
Couple that with improper grounding and overdriving mic preamps in
many rigs and you have a recipe for garbage - before even considering
all the windows noises, streaming audio, and open mic stuff that
gets on the air ... none of which happen with FSK.

While it may be true that a proper AFSK signal is cleaner than FSK in
many rigs (the K3 FSK is exceptionally clean - as clean as the filtered
AFSK), it takes very little to make AFSK absolute garbage - most users
can't mess up FSK any more than the manufacturer's design.

My radio laptop is a fairly new [1 yr] quad-core Acer running Windows
7.  On the spectrum analyzer, any undesirable products other than the
single tones are lost in the minuscule noise on the baseline.

There can be other reasons for running FSK with the extra interface
equipment which usually offers other features beside FSK, but for
someone just trying out RTTY, less is definitely more.  There is a
steady stream of traffic on this list from people trying to get
MicroHam, SignalLink, or other interfaces working, so it's definitely
not a piece of cake.  MMTTY is tough enough for a newbie.

The K3 does have a potential gotcha which is easy to avoid if you know
about it.  The RF Power is controlled by a closed-loop ALC system.  The
power knob sets the requested power, the loop then adjusts the drive
to make that power.  Consequently, you cannot adjust the output power
with the MIC/LINE IN front panel gain control.  Adjust the MIC/LINE IN
control for 4 solid ALC bars with the 5th just flickering when sending
idles [diddles].  Then set the desired power with the PWR knob.

There's almost no conversational RTTY anymore, it's pretty much all
contesting.

Unfortunately, K0SM's paper has flaws in its premise that render the
conclusions hardly persuasive.

1) the FSK measurements were made with the *original* K3 FSK generator
not the most recent shaped FSK.  Even though the original K3 FSK was
better than most, the current DSP implementation is much better and
provides FSK indistinguishable from the filtered AFSK.

2) the AFSK measurements were made using Line In and did not include
effects common to overdriving the microphone preamp as happens in
many rigs.

3) in the K3, AFSK_A disables mic compression and RF clipping.  That
is not the case in other transceivers operated in SSB mode.  The mic
compression and RF clipping is one source of AFSK distortion and
harmonic generation.

4) the AFSK measurements were made with the K3's AFSK TX filter in
line.  That filter removes substantially all the hum and distortion
present in other transceivers when the ground (audio) return is open,
the sound card DAC is driven into the distortion producing range
(typical at output levels greater than 60%), and/or the mic preamp is
being overdriven.  Andy's tests with all knobs full bore proved that
the K3 is capable of cleaning up signals that would be a disaster with
many other rigs.

5) The K3 does not use a closed loop ALC which generates overshoot
and pumping distortion.  Again, these effects are common on other
manufacturer's transceivers and are often responsible for a high
preponderance of the clicks in both FSK and AFSK signals from those
transceivers.

I have off the air spectrum captures of W1AW with their top of the
line Icom rigs and professional operators that show *all* of the
issues of overdrive, loss of signal return and ALC effects even when
driven by supposedly clean AFSK signals from fldigi.  Again, AFSK
requires far more operator attention to signal hygiene than does FSK
if the result is to be acceptable (that is, unless one is using a K3).

[Elecraft] Issues with TS590SG and KPA500 - the outcome

2015-01-30 Thread Barry Simpson
I have already posted details of the issues I have experienced trying to
interface my brand new TS590SG with my KPA500.

The TS590SG has different linear amplifier switching arrangements from the
TS590S and these mimic the TS990. Specifically Menu 59  #4 provides solid
state grounding via pin 7 of the remote connector for switching linears. I
use this method with my TS990 and it works fine. However, it does not work
with the TS590SG and the KPA500 goes into the transmit state permanently
once it is put into the operate position.

The relay switching Menu 59 #2 works very well but it is noisy.

Feedback I have received suggested that I try a diode in series with the
keying line. I tried it but absolutely no difference. Another suggestion
was a pull up resistor but I wasn't sure what to install and where.

Clearly in its original state, the solid state switching is incompatible
with the KPA500.

I have now reverted to the method I used with my earlier TS590S which is a
single transistor switch - a 2N3904 and a 2.2K resistor squeezed into the
shell of the Din plug. The connection to the TS590SG is via Pin 7 and the
setting is #1 which provides +12v on transmit which is what the TS590S also
does.

Suffice to say that this solution works perfectly and silence now reigns
again.

Hopefully either Kenwood or Elecraft will devise a simple solution to the
problem in due course.

Just an update which others may find of some help.

Re: [Elecraft] K3 and RTTY

2015-01-30 Thread Wes (N7WS)
Well, since the subject is K3 and RTTY, isn't it fairly safe to assume that a 
K3 would be in this picture?  If so, then AFSK is, IMHO, the simplest method and 
you agree that it is acceptable.

Unfortunately, K0SM's paper has flaws in its premise that render the
conclusions hardly persuasive.

1) the FSK measurements were made with the *original* K3 FSK generator
not the most recent shaped FSK.  Even though the original K3 FSK was
better than most, the current DSP implementation is much better and
provides FSK indistinguishable from the filtered AFSK.

2) the AFSK measurements were made using Line In and did not include
effects common to overdriving the microphone preamp as happens in
many rigs.

3) in the K3, AFSK_A disables mic compression and RF clipping. That
is not the case in other transceivers operated in SSB mode.  The mic
compression and RF clipping is one source of AFSK distortion and
harmonic generation.

4) the AFSK measurements were made with the K3's AFSK TX filter in
line.  That filter removes substantially all the hum and distortion
present in other transceivers when the ground (audio) return is open,
the sound card DAC is driven into the distortion producing range
(typical at output levels greater than 60%), and/or the mic preamp is
being overdriven.  Andy's tests with all knobs full bore proved that
the K3 is capable of cleaning up signals that would be a disaster with
many other rigs.

5) The K3 does not use a closed loop ALC which generates overshoot
and pumping distortion.  Again, these effects are common on other
manufacturer's transceivers and are often responsible for a high
preponderance of the clicks in both FSK and AFSK signals from those
transceivers.

I have off the air spectrum captures of W1AW with their top of the
line Icom rigs and professional operators that show *all* of the
issues of overdrive, loss of signal return and ALC effects even when
driven by supposedly clean AFSK signals from fldigi.  Again, AFSK
requires far more operator attention to signal hygiene than does FSK
if the result is to be acceptable (that is, unless one is using a K3).

Re: [Elecraft] K3 and RTTY

2015-01-30 Thread Fred Jensen
U ... I've never understood the infatuation with FSK over AFSK, 
especially for someone just trying RTTY out for the first time.  If the 
sound card produces clean audio [pure sine wave sans noise], and most 
newer ones do these days, the result at RF is essentially the same, with 
less equipment.  The K3 also has a shaping filter when running AFSK that 
makes AFSK cleaner than FSK, or so I've read.


My radio laptop is a fairly new [1 yr] quad-core Acer running Windows 
7.  On the spectrum analyzer, any undesirable products other than the 
single tones are lost in the minuscule noise on the baseline.


There can be other reasons for running FSK with the extra interface 
equipment which usually offers other features beside FSK, but for 
someone just trying out RTTY, less is definitely more.  There is a 
steady stream of traffic on this list from people trying to get 
MicroHam, SignalLink, or other interfaces working, so it's definitely 
not a piece of cake.  MMTTY is tough enough for a newbie.


The K3 does have a potential gotcha which is easy to avoid if you know 
about it.  The RF Power is controlled by a closed-loop ALC system.  The 
power knob sets the requested power, the loop then adjusts the drive 
to make that power.  Consequently, you cannot adjust the output power 
with the MIC/LINE IN front panel gain control.  Adjust the MIC/LINE IN 
control for 4 solid ALC bars with the 5th just flickering when sending 
idles [diddles].  Then set the desired power with the PWR knob.


There's almost no conversational RTTY anymore, it's pretty much all 
contesting.

Re: [Elecraft] K3 SO2V in digital modes

2015-01-30 Thread Joe Subich, W4TV


 What is the status of any firmware change to allow digital mode per
 VFO on the K3?

Not likely due to the synthesizer design.

 Meantime are there any workarounds?

You can certainly use AFSK (MMTTY USB) and PSK63 (MMVARI) or 2 x MMVARI
simultaneously in DATA_A - one on each receiver/VFO.

Re: [Elecraft] K3 SO2V in digital modes

2015-01-30 Thread Richard Ferch
The simplest workaround is to use AFSK. If you are capable of 
configuring your equipment so as to generate a clean PSK63 signal, it is 
within your ability to use AFSK to create a clean RTTY signal that is 
every bit as good as (or better than) an FSK RTTY signal.

[Elecraft] KPA500 Issue

2015-01-30 Thread Barry Simpson
My KPA500 has just developed an issue. Specifically when I switch it from
Stby to Oper, the level of received signals drops by around 5 or 6 s
points. It still transmits fine and there are no adverse SWR indications or
loose co-ax plugs. It does the same on all bands. I switch back to Stby and
the received signals return to normal.

I seem to recall that someone else posted details of a similar such problem
some time ago. Any suggestions would be helpful before I email the Elecraft
hot line.

It is now properly calibrated and thank you for the pointer.

 Subject: [Elecraft] Shift waterfall with P3
 
 I've noticed something happening with the P3 that I haven't found a
 way to resolve.
 
 The K3 is hearing a station on 1.825.010  Pushing spot verifies this
 is the optimal frequency I'm hearing them at.
 I have the P3 span sat the narrowest at 1.
 The centerline of the P3 displays 1.824.97
 Pressing CENTER on the the P3 says Center Frequency 1.825.0
 However, the signal is decidedly to the left of the center line on
 the P3 display.
 The peak of the signal is above the signal, not at 1.825.0
 
 It seems as if I could move the waterfall to the right 110 Hz, both
 would be in sync.
 
 I can't seem to find any mention  of an adjustment to get these in
 sync. Any suggestions?

Re: [Elecraft] KPA500 Issue

Hi Barry,

There is an asterisk that appears on the left side of the KPA500 display
whenever the key out signal from your transmitter is present. You should not
see the asterisk when you are receiving. If you are then is it possible that
you are using the key out signal to operate some other device in addition to
the KPA500?
