[Elecraft] K3 PLL Error Display

[Roy Morris]

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.  Roy Morris  W4WFB
