Band is on 40 meters. Probe must be O.K. because I can read TP3 O.K. Put probe into TP1. Upon initiating PLL, reads freq of ~12267.xx and then goes to Info 232. Used same probe to read BFO range so assume it is working. Just wanted to make sure I didn't leave anything out. It worked fine before I made the mod. Geoff, K6TFZ
