Also -- I haven't done any digital/data modes with
my KX3 as yet, and may not (have a K2/100 and a
K3/100 which may be more favorable for that than a
barefoot KX3). However, I do have a SignaLink USB
with cables for the KX3 so I may eventually use it
that way portable if the opportunity arises.
I suspect the thermal conditions will stay pretty
benign in CW and SSB modes.

Mine didn't do anything so "wavering" as yours
and it changed at a higher temp. So I wouldn't
expect to see much effect while operating, since
it was at high temps, above 42C.
My concern is if the calibration is off. If it
was a simple linear fit then it could be. If a
table look up or more complex fit then it should
still be good at a normal operating temp range.

Glad to know I wasn't the only one. In my case
the issue around 38 to 42C is a big deal
because that is where the PA sits when running
JT65. So it makes that mode unusable. If the
odd break didn't happen until 52C I'd be all
set. And it was definitely hopping all over
the place (sometimes rising, other times
lowering, and in larger step changes than I was
seeing before).
I'm not so sure this isn't a problem with the
radio locking onto a harmonic of the tone as it
shifts lower and lower in pitch. I need to run
the test sometime with a scope on the output to
see what the signal looks like as gets very low
in pitch.
Please let us know how it works out when you
try it on air.
