I am trying to reliably monitor the Buffalo police frequencies which use APCO-25 but NOT with trunking. On my PRO-652 I just need to enter them as conventional frequencies and as long as I'm sitting on it manually, hear everything fine. All the frequencies are a part of Scan List # 1 which contains these and a mix of trunked and analog conventional frequencies.
The problem comes in when I switch to scan mode. I notice every other object comes in reliably and scanning is normal. But for these APCO-25 frequencies, I only seem to get a handful of the actual traffic occurring. I noticed this after a few weeks when my particularly busy police district infrequently opened up with any voice traffic and I became suspicious. I went to the object for this district manually and was surprised to hear a regular stream of communication. As a test, I would press 'scan' just as a conversation was starting between dispatch and a patrol unit and sure enough, while in 'scan' mode, it doesn't pick it up!
Reception and signal strength are not an issue, the signal bars are all lit up while sitting on the object manually, and the audio loud and clear.
Why would APCO-25 traffic struggle to open up while scanning, but be "fine" while manual? I've poured over the documentation but find nothing that would hint at a solution.
...and before anyone suggests, I am not locking the channel out permanently or temporary. The lowercase l appears, solid.
Any ideas?...it's maddening.
Here is a link to my target frequencies (those for Buffalo PD).
