I am sitting at a good height in NE Abq, and side by side, my BCT15X is not receiving on 172.3 but my BCD436HP is. The 436 screen is indicating NFM but not even breaking squelch on the 15X. Both radios are connected to outside antennas.
(Update) I will receive traffic on 172.3 on the BCT15X, BUT only in scan, not on hold. I have no idea why.
