Hi Lee,
That sounds like it could be the problem. Where is the TCXO trimmer

Ray, I just checked my Argonaut V after a 10 minute warm-up and find the
frequency error at 10 Mhz is 6.8 hz. I have not done a calibration on
this rig
and being under 10 hz, don't think I will even try. Just a data point for
you.
