I have been having some flakey operation with the main receiver in SN 1292 recently which I believe I have cured for the moment by re-calibrating the main VCO. As suggested in the manual, I have been observing the PLL control voltages on the VFO B display. Depending on the band, it is varying from a low of about 1.5 volts to about 5.1 volts. I also notice that there is sometime a rather large difference between the PLL1 and PLL2 control voltages (about 2 volts) on a given band, but not in all cases. These voltages do not change much over several tens of KHz tuning on any given band. Do these values and actions sound reasonable? I don't recall seeing a table of acceptable PLL 1/2 control voltage ranges by band. Thanks for any insight,
