Re: [Elecraft] Elecraft CW Net Report

[Bill Frantz]

I had the same issues with the SSB nets. (The CW nets come 
during the dinner hour, and today I was at a family picnic dinner.)


On 20M I could hear over half of the stations, some at ESP 
levels, but only Steve, WM6P managed to hear me and relayed my 
checkin. This was running 100W from my K3 to a 2 element wire 
beam. I was hearing Eric, WB9JNZ at 55 to 57, but he couldn't 
hear me. I've always assumed that being in Chicago, he has a 
fairly high local noise floor. I'm out in the country and can 
hear quite well.


40M was a total bust. I could barely hear anyone, and no one 
could hear my 100W to a dipole.


The K3 and the two antennas worked well during Field Day, so I 
put it down to propagation. The question on 20M is why I could 
hear well and others couldn't hear me. It may be worthwhile to 
swap out the 20M antenna for another one and see if that 
improves things.


Of course, on Field Day, I did most of my Qs on CW or digital -- 
two points per Q vs. one after all. And, CW and digital can 
punch through when conditions aren't good enough for SSB.

Good Evening,

Both bands were weak, with noise and QSB.  But I was moderately 
successful given the conditions.  One strange thing, NO8V was stronger 
than either K6XK or K4TO.  That's just not normal :)  I did hear some 
ESP code on 20 meters but not well enough to convince me it wasn't just 
in my head.  It happens now and then.  Often when I'm working and a 
squeaky fan is on.

I sat down to start the 40 meter net and I listened for a while.  To 
nothing.  Not one sound.  I looked out the window and found the antenna 
still up.  I checked the switches and the antennas were both online.  
There was just no noise at all on 40 meters.  Two weeks ago that meant I 
worked no one.  I called CQ and K6PJV popped up; weakly, but there.  
Dale was spending the day inside where it's cool with his KX3 by his side.

On the next call I copied M0YK M0YK M0YK.  I stared at the paper 
trying to figure it out.  With code this good why hasn't he upgraded to 
a G call?  Then W0YK called again so I could hear the initial dit :)  I 
gave Ed a 329 and he proceeded to tell me he was on K4 number 2.  The 
second K4 to check in to ECN and it's number 2?  The first K4 was when 
K6KR checked in last year.  I don't think I got his SN but I am sure 
#001 is in Wayne's hands.  The K4s sound good guys.

Brian checked in with a weather report much like mine.  He lives 
closer to the ocean but the Pacific has been socked in for the last few 
weeks.  The clouds just comes inland a bit farther up here.  He was 
working on a clean sweep of the 13 colonies contest.  He needed a couple 
more on CW.

   Writing parallel code is getting easier.  Now to learn how to tune it 
for best performance.  If done well you can achieve teraFLOP 
performance.  If done poorly you can do worse than brute force on a

I have seen this happen when the K3 was connected to a computer via either USB

(like several times a second) to determine its’ frequency and/or other 
operating parameters. This can cause the K3 to miss the data line signal from 
the KPA500. My solution was to slow the polling rate of the PC software.

Re: [Elecraft] Strange Amplifier behavior

[Ken K6MR]

The only way the K3 knows that the KPA500 is in operate is via an AuxBus 
message.  So if it misses it for some reason, it won’t switch.  Be sure the 
cable between the radio Aux port and the amp is completely seated and such.  
And make it a habit to watch the front panel on the K3 when you switch on the 
KPA or select operate.  You should see the KPA500 Operate message.  The other 
way you can check is wiggle the PWR knob and make sure the * is in the window.  
That tells you that the radio is using the amp power settings.

Re: [Elecraft] Strange Amplifier behavior

[Fred Jensen]

Mine was so intermittent that I could never reconstruct the actions I 
had taken prior to seeing the anomaly ... often a month or more would go 
by.  I had the control cables between K3, KPA500, and KAT500 connected, 
and in every other way, the three components played together 
flawlessly.  It was discussed here back when the KPA500 first came out 
and the K3 FW had been changed to include the feature.  I don't recall 
that there was ever a diagnosis or resolution.

I can't answer your question but when I still had my KPA500, I had that

[Elecraft] Strange Amplifier behavior

[Tom Doligalski via Elecraft]

I have a relatively old K3, which I use together with a KPA500 and a KAT500. 
Most of the time this works flawlessly. 

However, occasionally the K3 gets confused and doesn’t realize that the KPA500 
is in “Operate” mode (rather an in standby). This results in the K3 sending 100 
watts to the amp, and the amp faults. 

Again, this doesn’t happen often, and I can’t ascertain why it occurs. Most of 
the time all is OK. 

The K3, KPA500 and the KAT500 all are running the latest firmware. 

Any idea?

[Elecraft] K3S less sensitive with K144XV Reference oscillator phase lock installed.

[Kees]

Dear subscribers,

After installing K144XV Ref osc. module the radio is less sensitive on 144
mHz. There is also a wheaping sound, low volume.
The module was installed according the last errata.
Transmitting works fine.

When the module is disassembled the radio, the senstivity is good.

Who has a suggestion to solve this problem?

[Elecraft] OT: need simple log uploader to LOTW

[eric norris via Elecraft]

I am extremely frustrated.  I use the logging function in WSJT-X for digial 
mode QSOs, which I effortlessly upload to LOTW, using nothing more than a 
trackball.
What I am looking for is an app, that runs on an android phone or tablet, that 
allows me to enter and upload CW and SSB QSOs that so far exist only paper.  
There are several apps I have tried, each more useless than the next.  I can't 
use the direct uploader on TSQL because of severe neck mobility issues.  For 
the same reason, I.can't use N1MM logger or any logging program that runs on a 
computer but which does not run on tablets or phones.  
Any help out there???  Thanks!
73, Eric WD6DBM

Re: [Elecraft] K2 Radio interface cable to connect MFJ-993B ATU

[Joe Subich, W4TV]

Best to ask MFJ how they detect TUNE mode in the K2, and once you 
have that answer, we can tell you how to construct the cable for 
both the PC and MFJ ATU connections.

Based on the MFJ manual, the 993B is looking for specific protocol
from the *TUNER* connection of the Kenwood or Yaesu transceivers or
a contact closure out/contact closure in ("start"/Tuning") of the
Icom AH-3/AH-4 tuners.

None of Elecraft's transceivers are compatible with those signaling
protocols.  Elecraft's transceivers/tuners communicate using Elecraft's
proprietary "Aux Bus" (protocol).

I doubt that there is any way to automate the K2/MFJ-993B interaction.

[Elecraft] KPA1500 PSU fan speed mod a success

[Peter Dougherty]

Hi all,
Just wanted to reach out and say a great big THANK YOU to my good friend and
fellow NJDXA and FRC member Dave, WO2X for taking point and finding a fix
for my perpetually noisy KPA-1500 power supply fan. It had always been
annoying, but after the Covid lockdown and my wife had to work from home,
she was in the office/hamshack here 10+ hours a day, and leaving the KPA
powered up in standby was just too loud for her to concentrate.

It cost about $64 shipped to get the replacement front panel LED board,
which includes a higher-value 3W resistor that reduces the idling fan noise
to almost nothing now. It's a very simple mod that in retrospect I could
have done myself, but for me with my shaky hands and not-great eyesight it's
a big plus to have a friend like Dave who knows his stuff. If you have an
older KPA1500 and the PSU fans (not the RF deck fans) were driving you nuts,
this mod works great, and eliminates a big source of frustration.

Good Evening,

   The days are growing shorter.  It was chilly all week.  Might be the 
lack of solar activity.  It may also be the clouds which can't seem to 
move off shore.  That left me quiet time with all the rain.  Time enough 
to study CUDA programming for two weeks. It is amazing what you can do 
with 32k threads of execution. Graphics cards are very powerful these days.


   As I mentioned, the sun has remained inactive.  A few tiny sunspots 
and a couple almost sunspots which melted away.  Even the solar wind is 
weak; the auroral oval is light to non-existent.  A few more comets may 
make their way around the sun this year.  Lots of duds lately though.  
It would be nice to have a long lasting comet for the fall.



Please join us on (or near):

Re: [Elecraft] K2 Radio interface cable to connect MFJ-993B ATU

Mike,

It is more complicated than that - there is no TUNE information on the 
RS-232 lines but if the MFJ ATU has a signal to activate TUNE on the K2, 
and I do not see any reference to a TUNE signal in the Kio2 Programmer's 
Reference manual.


Best to ask MFJ how they detect TUNE mode in the K2, and once you have 
that answer, we can tell you how to construct the cable for both the PC 
and MFJ ATU connections.
