When I power up my K3/100/KRX3, the secondary VFO display momentarily displays ERR PL1 or ERR PL2 and goes back to the VFO frequency display. I have just completed the synthesizer calibration procedure, and it still displays these error notices. However, if I tap DISP I get what looks like good PLL voltages on all bands on both PLL 1 and PLL 2. On occasion I might see a zero reading on a PLL voltage. When the radio warms up I don't see these PLL 1 and PLL 2 error displays. Should I reposition the KREF3 and KSYN3 boards into their sockets again? Should I reposition the TMP cables again to correct this condition? I did the KSYN3 mod by placing a 180K resistor in parallel with SMD resistor R10 on both KSYN3 boards to get a higher minimum VCO current. I also wonder if this might be an ESD problem in the hamshack. I would appreciate any responses. Thanks.
