[Elecraft] Elecraft CW Net Announcement

2008-08-03 Thread Kevin Rock
Good Evening (well, somewhere)
   It is late here.  The NAQP just got done and I had some fun in it.  I will 
not set the world on fire but I did make some contacts around my chores.  It 
has been a wet and cold week here.  It was nice for getting more wood ready for 
winter while it wasn't raining but that happened every single day.  Most days 
it cleared up by noon but it was pretty wet out.  It did get in the 70s a 
couple times but I had my first fire of the summer.  It was so cold Sam thought 
we should get warm.  I think it was more like a threat if I remember correctly 
;)  He speaks and everyone jumps.  
   Twenty meters was pretty good this week and today I worked stations on all 
contest bands except 10 and 160.  I could not quite get the folks on 10 meters 
and on 160 my SWR never got below 4 so I could not get out.  But the other 
bands were pretty good.  What does surprise me is the fastest folks out there 
require the most repeats.  Whether via the computer keyboard or via my paddles 
I had to send my information multiple times to many of the very fastest sending 
stations.  Those running below warp 9 were able to get my information first 
time.  It was an interesting contrast.  After a few hours I was able to get 
their information first time too.  I tried holding a frequency but never did 
too well.  SP was the order of the day for me.  It was fun to watch N1MM do 
its thing.  My biggest problem was losing my USB mouse connection over and over 
again.  I unplugged it and plugged it back in to get it working again.  
   I also heard quite a few stations I knew.  At one point AB7R blew me out of 
the room on 80 meters.  Greg I don't think you're supposed to be quite that 
strong!  Then I heard someone work K6DGW not too long ago.  I'll bet Fred is 
going to be sleeping late tomorrow :)  W0NTA was a good signal into Oregon on 
40 meters while AC0DS was strong on 20 meters.  Lots of interesting signals out 
there.  NAQP seems simple enough for even me to work in it.  It will be a few 
years before I can handle the contacts in the sweekpstakes ;)  

Please join us tomorrow evening.

They would not hear much difference, but they will probably be able to hear

at 2.7KHz or whatever, so some of the extra information will get through.

But you will be wasting power generating frequencies that are more or less
wasted on the station you are working, and which could be causing QRM or
simply taking up space that someone else could be using. In my opinion, it's
only appropriate to use ESSB when you know that the other station is also
equipped to receive it, on a band that is quiet enough that the wider signal
is not preventing someone else from having a QSO. From that standpoint, it
is a pity that it has to be enabled or disabled by going into the CONFIG
menu, because that seems to imply that it is a setting that people will
either use most of the time or not use at all, rather than something you
enable (perhaps using MODE ALT) for a particular contact when circumstances
permit, and then turn off when that contact has ended.

[Elecraft] Re: ESSB Works Well

2008-08-03 Thread Dave G4AON
It's easy to turn ESSB on/off by assigning it to one of the PF keys. 
You still have to toggle it on/off with the 1 key then exit the menu, 
but it's fairly quick and easy.


I would welcome a test with another ESSB station to try mine. I find a 
few AM stations around but hear very few ESSB QSOs. The K3 sounds superb 
at 2.8 KHz bandwidth, so with my deep voice I am not sure ESSB would be 
of any real use, but I would like to at least give it a try.

[Elecraft] bandwidth question of K2

2008-08-03 Thread Chris Waldrup
When I am set to LSB on 40 meters without any filter engaged, what is the 
bandwidth that I can receive? 
I am using my K2 as a tunable IF for a LF converter that I experiment with, and 
I heard a station last night that was well above where I was tuning (almost 20 
kHz) and I am trying to rationalize that to myself.

A K3 ESSB transmit signal at 3.0Khz+ bandwidth will be heard with slightly
more fidelity (i.e., wider passband) than a non-ESSB transmit signal when
received on a K3 with a 2.7Khz filter.  That's because
the non-ESSB K3 transmit signal has an approximately 2.5Khz wide passband
and doesn't fill the 2.7Khz receive passband.  The ESSB signal won't sound
distorted - you just won't hear the entire transmit passband, but it will
still sound very good.

Of course the ESSB transmit signal will be heard with increasing fidelity
(wider passband) as the receiving filter is widened.

FYI, there's a plot of the K3 transmit passband at the bottom of

N1MM and the K3 work together without necessarily needing additional 
hardware to key the K3. There may be an irritation where the K3 keys up 
as you boot up the PC, but apart from that it does work. Drop me an 
e-mail off-line and I will send you the screen grabs from N1MM showing 
the settings... Check your SPAM settings too as many don't like my

Re: [Elecraft] bandwidth question of K2

2008-08-03 Thread Geoffrey Mackenzie-Kennedy

Chris,

When you say 'without any filter engaged' am I right in assuming that this 
means that you have bypassed the KSB2's crystal filter and the K2's IF 
crystal filter?  If that is the case then the K2's circuits after its TUF 
mixer would behave in the same way as a simple direct conversion receiver, 
whose bandwidth would be determined by the two crystal filter just ahead of 
the product detector and the audio circuits. I don't have my K2 manual here 
to see if there is anything else.


However I suspect that the reason that you heard a station almost 20 kHz 
above where you were tuning is that it was being 'heard' by a spurious 
response of the K2 or your LF converter, or a combination of both. Another 
possibility is that a spurious response of your LF converter was hearing 
some oscillator in the K2, but I am assuming that the station 20 kHz up was 
a real station. If of any help I could run a spurious response check for you 
later this evening (our time) if you would let me know the LO frequency of 
your LF converter, the LF input frequency to which you were tuned, and the 
40m frequency to which your K2 was tuned when you heard the station 20 kHz 
above where you were tuned.

On-air testing shows FB reports and frequent enthusiastic responses from
those using conventional SSB receivers. 

That seems to be because a significant improvement in high frequency
response clearly helps intelligibility and the naturalness of the audio.
It is true that narrower bandwidths have been the standard in communications
for years, but that standard is based on a compromise between minimum
channel width and intelligibility. Compromise is the operative word.
There's plenty of evidence that using a little more bandwidth can improve
the quality and intelligibility of speech. 

Ideally, the receiving end should have a filter bandwidth matching the
transmitted signal, but no filter has a brick wall cutoff, no matter what
the ads say. So adding some high frequencies out around the high frequency
roll-off point of a normal SSB filter still adds significantly to the high
frequencies heard, even on a non-ESSB receiver. 

The K3 still limits audio below 200-300 Hz at the lower frequency end. That
avoids wasting lots of power in lower audio frequencies, but it does prevent
those who are interested from doing a big broadcast voice with lots of
bass pre-emphasis on the ham bands.

The K3's  transmit bandwidth can be controlled so you don't need to greatly
exceed the normal bandwidth transmitting ESSB. When talking to someone using
a conventional SSB receiver, there's probably not much advantage in going
over 3.5 kHz bandwidth - perhaps even less - unless his receiver has a
rather poor filter.

One thing I've found helpful in the past to get around this is to simply
take the free and open PDF and generate a copy of it with a password on
it.  then put it on a USB stick.  Then when they go to open it they see
its a secured PDF with a password.  Then when you're able to provide ths
super secret password they simply assume that you have permission from
the publisher.  :)  YMMV but its worked for me in the past. :)  Keep in
mind a lot of it has to do with your attitude when you enter the store.
You've gotta sell it through and through.  

Reminds me of the days a while back when it was my job to test bank
security.  Usually banks spent a ton of time working on their perimeter
systems before hiring us to find vulnerabilities simply to find that
usually their weakest point was their trusting employees! :)  But in
their industry you either get security or good customer service.  It's
hard to provide a good balance of both.

Re: [Elecraft] bandwidth question of K2

2008-08-03 Thread Chris Waldrup

Hi Geoff,

Thanks for your input.  I didn't disengage any filters but none of the three 
filters that I had programmed into the uinit were selected.
I do a lot of aeronautical NDB (non directional beacon) hunting and those 
were coming in normally .  I use a homebrew AMRAD LF converter with the IF 
at 7 Mhz.
Last night I decided to try my first attempt at DGPS beacon hunting, and the 
decoder software actually decodes the bit stream and gives information about 
the station.  The local NDB on 350 Khz was strong as usual last night.
I tuned to 7.302 Mhz (302 Khz) to tune what I thought was the semi local 
DGPS beacon in Greensboro.  I was getting ID's from DGPS stations in Holland 
and India, and I got a message that my computer was locked to one in 
Victoria Australia.  The one in Holland is at 302 Khz so I believe this one 
but the one in Australia is somewhere around 318 or 320 Khz.  The PC did 
take an hour to decode the 7 beacons, so I am not sure if something is 
wrong.  The signal I am getting is digital of some nature, so it isn't like 
the NDB's where you can hear CW.  I wasn't sure without any filter manually 
selected by me, how wide a signal I would be able to receive with the K2.

response of the K2 or your LF converter, or a combination of both. Another 
possibility is that a spurious response of your LF converter was hearing 
some oscillator in the K2, but I am assuming that the station 20 kHz up 
was a real station. If of any help I could run a spurious response check 
for you later this evening (our time) if you would let me know the LO 
frequency of your LF converter, the LF input frequency to which you were 
tuned, and the 40m frequency to which your K2 was tuned when you heard the 
station 20 kHz above where you were tuned.

When I am set to LSB on 40 meters without any filter engaged, what is the 
bandwidth that I can receive?
I am using my K2 as a tunable IF for a LF converter that I experiment 
with, and I heard a station last night that was well above where I was 
tuning (almost 20 kHz) and I am trying to rationalize that to myself.

I imagine you are copying and pasting the URL wrong. Why not go to the
Elecraft home page and navigate to the beta software download page from
there? Home Page - Software - K3 Software  Downloader - Beta release
instructions - FTP link.

If that still doesn't work, either your firewall is blocking FTP or you need
a better web browser (try Firefox.)

Re: [Elecraft] Re: Problems with K3 KXV3 IF Output Level?

2008-08-03 Thread Tim Heasman

Hi All,

I have just connected my TT RX 320 to the IF port on my K3, and there seems 
to be plenty of signal available.
With the K3 on 7030 kHz I could tune the RX320 right through the 41 m 
broadcast band.
The only pecularity is that the RX 320 needs to be tuned lf to go hf and 
vice versa and usb needs to be selected on 40m ssb to resolve the signals.


I also tried WinRad on the 320's IF and got a panoramic display working, 
only 24 kHz wide though.

[Elecraft] OT: fan control in MFJ-4225MV switching P/S

2008-08-03 Thread Nick-WA5BDU
This could almost be on topic, as the desire to control the fan in my 
MFJ-4225MV P/S is associated with my acquisition of a K3.  There was 
recently a discussion of switching power supplies for the K3 on the 
list.  I thought the MFJ unit was quiet while others found it to be 
noisy.  After the noisy fans in my FT-1000 and in my old PC left the 
shack, the MFJ P/S did become the loudest box in the vicinity. 

I had a sense that the P/S didn't really need that continuous fan 
activity, especially during low duty cycle operation or just listening.  
So I put a temperature sensor on a heat sink and use it to turn the fan 
on and off via a comparator circuit and MOSFET switch.  I think it's 
going to work out pretty well.  Of course, the simple circuit could be 
used on any P/S that runs the fan all the time but doesn't really need to.


Schematic and lots of rambling chatter about the little project are here --

[Elecraft] [K2] KNB2 vs. electric fence.

2008-08-03 Thread Joe Planisky

Hey folks,

I've recently started picking up relatively strong pulses at 1 second  
intervals on my K2.  I suspect they're coming from a new electric  
fence somewhere in the neighborhood.  But where they're coming from is  
immaterial to my question.


Should the KNB2 noise blanker be effective against this type of  
noise?  I've always thought that such impulse type noise was exactly  
what noise blankers were supposed to work best on, but I hear no  
difference in the pulses whether the NB is on or off, nor at high or  
low threshold settings.  This is making me question whether the NB is  
working at all.


Any thoughts?

My guess is that there is some setting, perhaps in your browser but possibly
in your firewall, that is denying you FTP access.

My copy of IE7 gives me direct access to the FTP directory without launching
a separate FTP client. When I look in my browser settings under the Advanced
tab, I see that I have Enable FTP folder view checked - maybe that might
have something to do with it(?).

Some electric fences produce wide pulses, so you should try using the 
NB2 setting. If that doesn't work, you might consider increasing one of 
the capacitors that determines the pulse width in the KNB2; if you go to 
http://www.qslnet.de/member/la3za/K2/mod.html and scroll down to the 
KNB2 section you will see a note about it. I think the appropriate 
modification is to increase C12, which affects the NB2 setting. It is 
0.068 mf and you could try 0.1 mf.

[Elecraft] KX-1 DC Power Connector

2008-08-03 Thread thomaskd
I have a KX-1 that I use portable.  Recently I took it into the woods and had 
some issues with the power shutting off.  I took it apart this weekend and 
traced the issue to the J1 DC power connector.  It is soldered solidly to the 
PCB but the pin inside it is loose.  When the power cable moves or I move the 
radio, it loses power.  I need to replace this.  (I think one of the kids 
tripped over the power cord when I had  it setup in the house last winter.)

Is there an exact replacement I can get from Mouser? I need to order some parts 
from them anyway.  Or should I just go with the Elecraft parts service?

Thanks for any adviceI would like to get this back on the air!

Re: [Elecraft] K3 Beta Firmware Release -- MCU Revision 2.22

2008-08-03 Thread Matt Zilmer
You have to use the 6 KHz filter for TX on ESSB.  You're TX is
probably restricted on audio bandwidth with the 2.7 filter.

From hfnotes.rtf for 2.23: 

* ESSB (EXTENDED SINGLE SIDEBAND) ADDED:  Allows the K3 to transmit in
SSB  modes at a bandwidth of up to about 4 kHz. Requires a 6 kHz
crystal filter on the RF board. 

To use ESSB: 
(1) Make sure the 6 kHz filter is configured correctly  for AM
transmit; switch to AM mode, then specify this filter using
CONFIG:FLTX AM.  
(2) Locate CONFIG:TX ESSB. Select the desired extended bandwidth for
SSB ransmit (3.0 to 4.0 kHz) using VFO A. Then tap1  on the keypad
to turn ESSB on/off. When on, the + icon in the mode area will turn
on.

[Elecraft] K3 Programming

2008-08-03 Thread Lee Buller


I am working on a computer program to run the K3.  Yes, I know...there are 
already some out there, but I have an interest about doing this program.

I need to ask some questions to someone who has done work with talking with the 
K3 or the K2.

I have a working program, but I want to make it better.

any Common Sense, ask for help from somebody who has some Common Sense.  Is 
Common Sense divine?

Re: [Elecraft] [K2] KNB2 vs. electric fence.

2008-08-03 Thread Joe Planisky

Thanks for the responses, Dale and Vic.

I tried increasing C12 to 0.1uF, no change.

I tried turning on the preamp, again no change.

I did some research on the web and it seems the effectiveness of the  
KNB2 has been the subject of some discussion in the past.  A handful  
of folks even shared my suspicion that their KNB2 was not working at  
all.   I was able to verify that my KNB2 was indeed working by  
connecting a short piece of wire to the antenna jack and scraping it  
against various metallic objects in the shack with the NB on and off.   
(I tried the light dimmer trick, but I must have the worlds quietest  
light dimmer.  Never thought that would be a problem!)


What did seem to help was the mod suggested by DL7MAJ:

http://www.dl7maj.de/KNB2-Mod.pdf

which adds a 0.1uF capacitor between the emitter of Q2 and ground.   
This increases the low-threshold sensitivity.  Before, I never noticed  
any difference between the LEVEL=LO and LEVEL=HI settings.  Now there  
is most definitely a difference and the LO setting takes out at least  
some of the pops.


Thanks again for your responses.

Some electric fences produce wide pulses, so you should try using  
the NB2 setting. If that doesn't work, you might consider increasing  
one of the capacitors that determines the pulse width in the KNB2;

[Elecraft] Re: K3 - KRX3 shipping question

2008-08-03 Thread Dave G4AON
Bruce, I phoned and spoke with Katie last week to as about the 
availability of the KXV3 and also asked about the 2nd receiver. Well the 
good news is the KXV3 is more or less available from stock... The bad 
news is the KRX3 takes around 4 months to deliver. My KXV3 shipped last 
week, but I'm going to sit it out for a while longer on the 2nd 
receiver. I am looking to try a hybrid coupler between the RX in/out 
sockets on the KXV3 to feed an external receiver (marginally less loss 
than a resistive splitter, being external I can easily try both to see 
the difference), I might even look at how practical it is to add a 
buffer amplifier in the K3 to bring out an unattenuated signal but I 
don't want to compromise the K3 performance in doing so. I will be more 
than happy to leave the external receiver on one frequency and tune 
around with the K3, if that external RX's QRG is stored in the K3's 
alternative VFO or one of the quick memories, I can quickly transmit on 
the external RX frequency. Muting the external receiver is not hard either.


I've already done the above (with an internal buffer amp) on my K2, so 
it will be interesting to see how it turns out on the K3.

Yes, just call me impatient. Now that my K3s have been built and on the air
for several weeks I am anxious to take them apart to install the KRX3s. I
have seen several mine is shipping emails, but what would be nice to see
is specific info like is listed for the K3s.

Example - We are shipping X' qty / week. The backlog is Y. Something
that would give those of us that don't have K3s in the low three digit
serial numbers some idea when our next package might arrive. Is this
possible and reasonable??

If I have missed such a notification, I apologize.

[Elecraft] Elecraft CW Net Report for August 3rd 4th, 2008

2008-08-03 Thread Kevin Rock
Good Evening,
   Combining wood splitting, hauling, stacking, roof material unloading, 
hauling, ladder lifting, stacking, and then a net in one day has proven a bit 
much for me.  I am tired!  However, it does keep me active, fit, and drinking 
plenty of water.  It may even be heart smart!  Today the weather may have 
broken.  The rains stopped around ten, the sun came out around noon, and the 
temperatures got to the low 70s.  Predictions are for mid 80 degree 
temperatures this week.  Great time to get up on a roof and fix it :)  As long 
as I don't fall off I'll be fine.  I may be seeing little space ships flying 
around by the end of the week.  Who knows they may take me with them! 
   The nets went well today.  Both of them ran for over 40 minutes.  QRN on 20 
meters was very light and was medium light on 40 meters.  Northern California 
was booming in here today.  Both Fred and Dale were ear splittingly loud.  But, 
since the QRN was light, my walk after the second net was not too long.  I just 
went out and carried wood for a while and then looked for Mt. St. Helens.  It 
is too brown this time of year to show up very well but I tried.  The foxglove 
and fireweed are foretelling the end of summer soon.  Good thing the woodpile 
is growing apace.

   If there are any errors in these lists I would not be surprised!  I am way 
too tired.  But the roofing is on the roof and not in my truck.  Gas mileage 
was terrible when the back was full of roofing material!  But, once all the 
holes from that darned tree are patched, the roofing and all the ice and water 
shield and black jack are down I will have a good roof.  I can then move to the 
next project: drywall.  That fun will continue until I have to close the 
windows for winter.  I will be warmer this year.  Plus the tree which fell on 
my house will be in the firebox a little bit each day keeping me warm!  
Vengeance?  No, just good sense ;)  Getting the rest of the downed trees 
cleaned up will take a number of years.  But it is a great health plan.  Maybe 
I should sell memberships to my club ;)
   Until next week stay well,
  73,
 Kevin.  KD5ONS (Net Control Operator 5th Class)
