QCX 40M - GPS Calibration shifter VCO?


W.John Guineau
 

Hi,

I recently built a QCX 40M. I also built a QLG1 GPS unit.

Prior to calibrating with thew GPS, I would set the QCX to 7.117.00 but on my IC-7300 I would pick it up on 7117.35 (+/- a few Hz).

After GPS Cal, I have a much bigger discrepancy between IC-7300 and QCX. Setting g QCX to 7.117.00 requires the IC-7300 to be at 7.115.45 to both TX and RX with QCX.

Does this indicate that I need to redo all the alignment corrections again?
