[Elecraft] Unusual problem with KPA500

[marvwheeler]

My problem only occurs on 160 meters. If the KPA500 is in stand-by I receive
no signals on the K3S. Simply switching the amp to operate lets signals
pass. I have tied different antennas jacks on the KAT500 and the problem
remains. I sent an email to Elecraft support about a week ago and have not
had a response. Anyone have any ideas? Thanks

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   Twenty meters was busy.  The RTTY folks were on 14050 and above.  
The WES folks were below 14050.  I found a spot, and held it, from 2150z 
onward.  However, I only had one station find me. I did pick up a stray 
from New York while waiting to start the net.  Weather reports were 
fairly normal for February.  The Midwestern folks insisted on putting 
either minus ahead of the number or below zero after it.  I think they 
both may be wearing hats and gloves this week.


   QSB was moderate on both bands.  40 meters did change rapidly over a 
few minutes.  As the solar cycle picks up I think this change will be 
less sharp.  I need to check the MUF, it might be close to 7 MHz.  Noise 
was low on each band.



  On 14049.0 kHz at 2200z:

WA2JSB - Robert - NY

K6XK - Roy - IA


  On 7047.5 kHz at z:

W0CZ - Ken - ND

K0DTJ - Brian - CA

WM5F - Dwight - ID

K6XK - Roy - IA

K6PJV - Dale - CA


  I plan to spend some time being snowed in.  With all the snow it is 
pretty quiet and the traffic has been cut to one vehicle a day.  Even 
the aircraft beacon at the top of mountain is not well used.  But ears 
adjust.  As there is less noise they find the level below.  I don't 
think I have ever been in a truly sound free environment; even in a cave 
there was the dripping.  Mr. Bell studied this logarithmic response and 
has his name misspelled as its unit.  Volt(a), Ampere, ohm, Oersted, 
Henry, but bel?



  Until next week enjoy your version of winter.

  73,   Kevin.  KD5ONS

Re: [Elecraft] K3 assembly issue

[Alan Bloom]

Unassembled Heathkits have sold for amazing amounts of money.  (I use 
the past tense because I doubt there any of those treasures left these 
days.)


I have even heard of people "making" an unassembled kit by  buying a 
built one, taking it apart, unsoldering all the components, and 
replacing the soldered parts with new ones.  Apparently it is 
financially worthwhile to do that.   :=)

Same as "MAC" for the computer, or an urban legend -- they picked it up

Just don't scream "ham". It's not an acronym, and there's no reason to put
it in all caps. I have no idea why people keep insisting on capitalizing
it? I know it's off-topic, but why do people do that? Does anyone know?

Re: [Elecraft] K3 assembly voltage regulator failure

Adrian,

If you can find no solder bridges, then
Yes, replace the regulator.

[Elecraft] K3 assembly issue

[KJ7SOY]

Hi everyone! I’m new to the list and to Elecraft radios and HAM in general. 
Thanks for bearing with me while I learn!

I picked up an unassembled K3 at an auction three weeks ago. It’s been sitting 
in a box with most of the boards sealed in their anti-static bags since 2009. 
I’ve hit a snag and I’m hoping someone here can help. 

I have the rev B RF board and I’m doing the manual’s resistance tests. Voltage 
regulators U12 and U13 are both supposed to test at > 150 ohms. U12 passes but 
U13 tests at 87 ohms. This unit has never been powered up so I suspect it has 
to be a bad regulator. I can solder a board just fine and assemble PCB’s but 
I’m not overly comfortable with hardware debugging. I’ve removed the side cover 
and checked for loose boards, bad connections, etc. with no success. Anyone 
have any ideas how I should proceed? Do I just replace the regulator? Do some 
other debugging?

Thanks!

[Elecraft] KXPA100 Fault on ANT1

[gerald.eberle]

@ N7WA

Hi Dink

Many thanks for your help. It turned out to be the same issue as you 
experienced. After removing the ANT1 SO239 connection from the ATU board I’ve 
measured also a shorted cable. To be sure that there are no other issues, I 
connected the ANT2 SO239 to ANT1 on the ATU board and voila, ANT1 it is 
working! So, I only have to get a replacement cable to have both Antenna 
sockets back again in working order.
