I hope this doesn't result in the need for an exhaustive review of trunking - which would probably mean I'd 'exhaust' everyone's patience!
I have monitored a local (nearest tower about 5 miles away) Moto P25 trunked system for several months. Reception has been outstanding and I've even had to lock-out certain Talk Group IDs because traffic was almost constant and I missed other, more interesting transmissions.
Suddenly (today) I'm receiving almost nothing on this system. The Control Channel seems to "fade away" for minutes at a time ['NFM' replaces the CC frequency on my BCD996T display]. When I do receive a transmission, it's often one side of the exchange.
Here's the conceptual question: since trunked systems are not the traditional base/mobile pairing where one signal (the base) would be expected to carry farther due to higher power, and the signal from a mobile unit or a dispatch point should arrive at my scanner with the same strength on one of the equal-power voice channels, why might I be receiving only a few transmissions?
Sorry - no prize for correct answers other than knowing you've helped me with a very perplexing question.
Thanks!
