Don and Brian:
I had good luck just using my XG3 as signal source for the temp
compensation on 50-MHz.
I did monitor freq on my prof. counter.

Brian,
The XG50 is not really expensive and is a good stable source. It is
'cheap' compared to the frustration factor involved with trying to use
other methods.
If you have access to an instrument lab with highly stable signal
sources in the 50MHz range, then you are all set, but most are
I ran the KX3 temp compensation procedure twice (the first run was a
learning experience so feel I got a good run on #2). I used my AG3
coupled with a very good freq counter.
JT65 is a synchronous code so that demands good frequency control
(<+/- 10 Hz) and near perfect timing (< 1 second).
I would agree with the ext temp compensation. It is the right thing to do
and let's the onboard computer handle the drift variations for you. I
don't have the xg50, which is recommended. I tried the wwv approach and
that did not work, even when wwv was coming in fairly strong at s7. I
watched
Keith - don't know if you had the temp compensation alignment done but you
also need to ensure your PC is accurate, "time wise " - I downloaded this
freeware.http://www.thinkman.com/dimension4/download.htm

Keith,
Have you done the Extended Temperature Compensation procedure on that KX3?
If not, you should do that. It should reduce that drift due to
temperature significantly.

I am experiencing some frequency drift on operating JT65 with KX3 + KXPA100. I
was reported that my signal drifted 5 to 8Hz drift during my transmission and
noticed almost same amount of drift during my receiving period.
Output power was 20W with KXPA100. OSC temp shows 36C on receiving and 39C
