Greetings,
I've been very happy with my TRX-1, except for one issue . . . it's gone completely deaf on a local simulcast system that its older brother, the PSR-800, continues to receive surprisingly well.
I've set and re-set and loaded, erased, and re-loaded the 400 MHz trunked P25 system and tinkered with every setting available in the scanner (FM, NFM, AGC on and off, audio boost on and off, Advanced DSP Settings, etc.), but it remains silent. The signal-strength meter flickers at full bars when it locks onto a talkgroup, but no audio comes through. And yes, I've duplicated as best I can the PSR-800's programming in the TRX-1.
When I first purchased the TRX-1, its performance on this simulcast system was comparable to the PSR-800's, but something has happened in the meantime that I'm at a loss to understand. One of my current theories is that the transmitters in the trunked system are further out of synch with each other than they may have been previously and that the TRX-1 can't handle the bit error gap as well as its predecessor.
For what it's worth, my Uniden scanners ('436, '325, and '396) do a pretty good job with this simulcast system, but it's hard to compare them to their Whistler/GRE brethren because the Uniden's P25 threshold levels can be set manually--a feature that makes a huge difference in their simulcast performance.
Ideas, anyone?
Thanks!
