I've been googling this for days to no avail so I'm hoping the Uniden experts here can shed some light on this. I'm near San Jose, CA and I've been listening for years (BCD436HP) to a local P25 (phase 2 I think) sheriff department (Santa Clara County Sheriff West division on 155.700MHz). All of a sudden, I now only hear the dispatch traffic and none of the traffic from the units, but the dispatcher is responding to them in conversation. This did not happen for years until now. The dispatcher's transmissions are fairly clear, but they do cut in/out occasionally so I've tried lowering the Digital Threshold to Manual, then 6 (was 8) with no benefit. I was on a 4 years old firmware version and I just updated it to 1.26.00 recently, so could that be causing it? Is there any setting that could be causing me to hear only one half of the conversations? I've tried other antennas including a base station one and that didn't help. I'm still hearing only the dispatcher. I thought there might be a simple setting but I'm pulling out my hair about this.
