Has anyone ever noticed a reception/performance difference between FM and NFM modulation settings on the TRX-1 . . . or any other commercial scanners for that matter?
As an experiment, I reset all the FM channels in my TRX-1 to NFM. It may have been my imagination (or a slow night for radio communications), but it seemed that I received fewer signals after that change, with the exception of digital signals, which continued to come in loud and clear.
I know that Uniden's BCD436HP is supposed to have "true narrow band filters," but I can't help but wonder if the FM/NFM modulation choice on most commercial scanners might be cosmetic.
RadioReference database information for my listening region (northern New Mexico) has a mix of both modulation types, even though everyone was supposed to have transitioned to narrowband after the 2013 FCC order.
Thanks!
