[Elecraft] K3 Help with KRX3 Installation PL2 Error?

[Allan Bacon]

K3 #2252 Factory built, now adding KRX3. Do not want an exotic setup, just want to listen on one frequency and transmit on another - same band, same antenna.

Completed installation with no problem, Used good static mat and wrist strap. Uploaded latest firmware. Unsed Config Menu to initialize as ANT-BMC (seemed like the default I wanted to use) . Do not have a TMP cable plugged in to J92, as I believe this is how to keep it simple for what I want to do.

Per troubleshooting chart on a PL2 Error, I tried recalibrating the VCO with VCO (CONGIG:VCO:MD), taped SBU, screen showed 255, and SUB starts flashing slowly. Rebooted, Still get PL2 Error.

VFO A and B seem to work fine

Looking for help please -
