Re: [Elecraft] KX2 Display

[Brian Hunt]

Jim -

I'm not sure this will help but here goes

I have KX2 SN 11xx with current firmware loaded:  uC 2.89, DSP 1.52.  
I've reviewed all the update information and there doesn't appear to be 
any changes that would modify the behavior of the DISP function.  Mine 
works as described on page 23 of the KX2 manual Rev. A5 dated May 28, 
2916: Special VFO B Displays -- Tap the DISP button and rotate the OFS/B 
knob to display the various parameters available.  The "Log" function 
was added in uC 2.77 and isn't covered in my manual version but works as 
described in the Firmware Notes for that release.


You could consider reloading the firmware fresh from the Elecraft site 
or call Elecraft support and pose the question to them.


73,
Brian, K0DTJ

When I try to bring up the DISPLAY function it does not work. The same
button when held does work. Just the DISPLAY does not respond as it is
supposed to do.

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   Roy, K6XK, mentioned not having any earthquakes this week. During my 
formative years in Wisconsin I had never felt one.  Then in 1972 or '73 
the New Madrid fault in Missouri let loose. Instead of working on 
chemistry problems I was reading Ambrose Bierce in my third floor room 
across from Camp Randall Stadium. Spooky stories set in the antebellum 
South.  Then the chairs start to shake, the pulls on the dresser began 
to rattle, and my bed started swaying.  Needless to say my hair stood on 
end.  It wasn't until the next day when I found out we had had an 
earthquake.  Now that I live in Oregon small quakes are common place.  
They sound like the couplings on a train when it starts moving.


   You know that feeling of hubris you have just before your plumbing 
project bites back?  I had one of those moments this week thinking I was 
only 30 minutes away from being done.  Wrong.  The connecting hoses I 
wanted to reuse were two inches too short.  The effort took its toll on 
my fingers.  If I sent code too slowly my fingers would get stuck open 
or closed.  Either way made it difficult to shape some words.  Plumbers 
truly are worth what they charge us :)



  On 14050.5 kHz at 2200z:

K6XK - Roy - IA

K4TO - Dave - KY

K0DTJ - Brian - CA

W0CZ - Ken - ND

K4JPN - Steve - GA


  On 7047.5 kHz at z:

K0DTJ - Brian - CA

W6JHB - Jim - CA

K6PJV - Dale - CA


   Now to go soak my hands in hot water as I do the dishes. However, 
there is more plumbing in my future.


    73,

    Kevin.  KD5ONS

[Elecraft] K3: Update - Antenna not connecting on change to BC frequencies

[Nigel ZL2DF]

Initially posted 6/5/19, now solved. The problem was signal
intermittency with an installed KBPF3 when switch to frequencies below
1.700.

 

With patient help from Keith WE6R at Elecraft and suggestions from 5 other
list members I was able to confirm the problem was on the KBPF3 board.
Further tests to map the relay switching frequencies from 0.5 to 30Mhz
confirmed that while various  relay switching were not consistent they were
all operating when energized.This then suggested faulty U1 and U2,
or corrupt control signals.Three TPIC6C595D from Elecraft were ordered.
These shift registers are daisy chained on their control line so I initially
changed out U1 (first experience at working with this sized IC).
Happily this solved the problem.Along the way I performed an EE INIT
on the radio and did a full calibration so now have a more detailed
understanding of the radio.

 

Warm thanks to Keith WE6R, Bill NR4C, Ben W4SC, Dave W9PA, Mark WB9CIF and
Mike VP8NO.

 

73,  Nigel ZL2DF

Re: [Elecraft] Fwd: K4/K4D antenna ports.

[Nr4c]

I believe the answer is One for K4(D) without ATU.  You get two others with 
ATU.

Re: [Elecraft] K2 PLL reference oscillator problems (DAC side!)

[Don Wilhelm]

Ryan,

Those sub-par J310s should work in all other circuits in the K2.
The only other possible exception is Q18, but if you can successfully 
run CAL PLL, then all should be OK at Q18 as well.


The problem J310s at Elecraft was resolved early this year and the 
incidences of this problem should be diminishing soon.

[Elecraft] K2 REC/MEM is OK, I was the problem.

[Steves_Mini]

I have been using my cootie so long that I forgot it was a cootie.  I have a 
Bengali paddle that I jumped to make it a cootie to use on my K2.  I had 
changed the menu setting to hand.  Well, when I tried to update my memory in 
button #6 for use with the 13 Colonies event, my radio was ignoring me.  Would 
not let me change anything, but it would play what was there already.  I wanted 
to put in just my Call.  After much effort in trying to figure this out, I went 
to the manual, found that it must be a paddle only, and it came to me that I 
was using my paddle as a cootie all this time, and just forgot it was not a 
paddle.  I removed the jumper, changed the menu from hand to paddle, and tried 
it again.  All was fine.  Radio likes me again :-)   Bottom line is…. for me to 
make sure I am using a paddle when trying to change K2 Memories.  73,  Steve -

Yes. Also, any one of the ATU antenna jacks can be designated as a third

[Elecraft] KPA500 Problem

[Andy Durbin]

"I have a KPA500 with a low HV reading. It is on the center tap and AC voltage 
is 115v No load and 110v full load. The HV goes from 77v NL to 56v FL (500W 
output)  Is that something I should look into? "

The KPA500 high voltage (nominal 60 volt) power supply is unregulated. The 
mains power input to the KPA500 is probably poorly regulated.   The voltage 
drop you will see on the mains input and the KPA500 60 volt supply is directly 
dependent on the PA current and you don't say what that was.

The fact that you have 500W output at 56 V does not define the PA current.  PA 
current, PA dissipation, and PA efficiency, are strongly dependent on the load 
presented by the antenna system.

My limited experience with the KPA500 suggests that you should:
  Attempt to minimize voltage drop in the mains feed
  Present the KPA500 with a load as close to R50 j0 as possible
  Keep PA voltage above 60 volts for all operating conditions
  Avoid nuisance high voltage warnings

How close you come to meeting those goals is partly dependent on the variation 
in the unloaded voltage at the mains outlet that you are using. (Summer HVAC 
use causes several volts variation at my nominal 120 V outlet even though the 
street transformer is less than 50 ft from my KPA500).   

Some data for my station:
Mains voltage is now 123.0 V and my KPA PA voltage is 81.5.   A TX into a  
dummy load (R 51 X 0.4) at 14.074 MHz showed mains voltage 117.8,  RF out 487 
W, PA V/I 62.6 V / 14.0 A, PA Diss 389 W, efficiency 55%.

My mains drop of 5 V matches yours.  My PA voltage drop of 18.9 V  is lower 
than your drop of 21 V and I would expect the difference to be explained by a 
difference in PA current.

Andy, k3wyc
