Hi Mike,
Wow! I apologize for the problem.
I believe we reviewed your config file and fault log on Friday and we are
authorizing return of the RF deck at our cost and will send you prepaid UPS
shipping label on Monday. I will stay on top of this to make sure it proceeds
quickly.
I will take

I know a number of KPA1500s have been returned to you with one of the
output transistors dead. Is there common source for the problem that
the rest of us can try and avoid?

Stiction of non lubricated threads can give a false sense of tight
connection. PL259/SO239 in particular can have poor contact through the
ground conductors while the thread seems tight.
When the threads are lubricated stiction does not occur and hand
tightening always ensures that the front

Right Gary, a 7/8 EIA flange would be a much better radio connector:)
Actually I have a few 4.3-10 connecters, they should be an easy swap with
SO-239/N jacks but I have yet to use one and I certainly would not do this
on my K3S.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This allows
very tight snugging by hand, no need of wrenching.

Amphenol 83-1SP connectors are great however I have a number of Andrew

If you live in North America, the ONLY good PL-259 connector is one

Do not trust PL-259 connectors installed only
Guys
the problem here is not who use PL259 or what coaxial is using. I think
Peter and most of us, and mostly if you do contests, is not that, we are
using good coax and connectors over the years and no problem with other
radios or amplifiers, thats what Peter said.
If you are in a contest, you
I don't contest in RTTY (I don't use that mode other than for Dxpeditions)

I have no idea why it would fail. I did have some issues in the past with
antennas going stupid on me or the HF-Auto tuner failing to match when

Hi Peter,
I'm sorry to hear about this failure and deeply apologize for the problem.
I'll follow up with another email to you to diagnose what actually happened.
In any case we'll deal with it quickly and get your amp repaired asap.

It would be nice to know why

I think a two-tone test is the best evaluation tool.. The generator
is built into the K3 if you have another receiver that you can use
to listen to the amp output. I use an SDR-IQ which is a very nice
tool for this but any other SDR would do.
Sorry for your pain.
