Hello!

I think you should go over all the solder joints on the control board.
Just heat them up and apply a tiny bit of solder. Wait till it flows. It
is not a good solution to leave out the screws, because oxidation may
ultimately make the bad solder joints fail even when the board is not
stressed.
Kevin,
That is "telling" that you have not truly flush trimmed the lead on the
encoder board and the area of the control board where it makes potential
contact. There is not a lot of space for error there.
Flush trimmed means really flush with the board thickness. Solder that
protrudes fr
Te kit should fit together without needing to use longer screws, etc.. If it
doesn't, then it indicates you may have done something wrong.
Are the PCB headers sitting properly flush wi the board, or are they sticking
up a bit, possibly causing misalignment? Are you sure you used the right size
Many thanks to Don and others who responded.
The problem has been fixed, I found a suspect dry joint on the PTT/ATT
switch.
I also checked the new encoder which appeared ok but I did insert a very
thin piece of insulation between the new encoder and the control board
to make sure.
All tests
You could try 2 x 12V fans in series to give a bigger cooling area but
smaller current; I did this once on a noise-critical application.
In terms of S units at the other end, turning down the power, say 25% makes
sense.

No larger heat sink exists that I've heard of.
I believe you said you run a high duty mode. If
so, the existing heat sink should be fine if you
back the power down to 25-30 W. Not so good at 100
W and high duty cycle.

I have never heard of a third party replacement heat sink for the K2/100.
I run a 4" (120mm) computer case fan that the specs say draws all of .15

It probably doesn't need to turn that fast to adequately cool the heat
sink so the current draw could be much l
Hi all,
I finally got to try the K3 in a contest... Very nice rig... I flushed
out all the macros, and got it running well, but for the serial port
slowdown all went almost perfect!

John,
Yes, you can do that. It is only the K2 that has problems with a
standard serial cable.

Dick,
That's exactly what happenedafter a lot of detective work, I determined
that my Ameriton remote switch is being flakey. It started to act up in the
RTTY contest. After the CQWW RTTY contest, I am going to take it apart and
check out what is happening..
So at least I know my KAT500 i

My point is to avoid using fans to cool this radio so as not to aid in
depleting the batteries in this emergency radio go box, while creating
additional noise for the operator. I'm on the fence as whether to take this

Hello Elecrafters,
It is off topic and only for those interested in Hong Kong. I further
understand that amateur radio should not touch about politics so I now simply
speak the facts.

Kevin, VK5KS has met exactly the same problem with the encoder, as I did.
Even flush,flush cutting of the leads did not solve the problem due to
a nearly imperceptibly slight bend of the control board.
The solution is to slide down an extremely thin sheet of plastic

Yes. And almost any generic muffin fan will push some air across a heat
sink or into a power amp to improve air flow. I have a couple of 12V
vans with power poles on them that I deploy as needed.
