The BCD536HP has the same bug I already reported to Paul in the HP1 with Discovery mode. The search hangs up forever on a P25 control channel with the Avoid button disabled so you can't move past it. This is demonstrated with the 407.8375 MHz P25 control channel in Houston. Discovery mode is useless if it includes the P25 control channel in the search range. I'm curious if anyone else has experienced this issue or if there is some oddity of the control channel in Houston.
