Unfortunately, without knowing on which frequency you were listening to 
WWV, it’s difficult to gauge your K3’s temperature stability. Were you 
listening on 5, 10, or 15 MHz?

Hi Gary,

Yes, I sure did forget to give the frequency in my last post. It was on 
5 Mhz WWV. (I could not hear 10 or 15Mhz at all at the time)

I did just did the test again, this time on 10 Mhz (still could not hear 
15 Mhz very well) and I got about 18-20 hz drift during an increase of 
about 10c front panel temp. That again is with the 5ppm TXCO. I think 
that would be pretty consistent with my previous result.
