[TenTec] Argo V calibration

[Rsoifer at aol.com]

Hi Lee,
 
That sounds like it could be the problem.  Where is the TCXO trimmer  
located in the Argo V?
 
Tnx, Ray

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.

73,
