What kind of results are you getting with the firmware "updates" on the 396/996 on digital systems in Tennessee? I'd really like to know what folks in Memphis and Nashville think. I'm still not sure what to think here in 'Nooga.
I am not in the areas you asked about, but my P25 decode is a lot better.
I do have some issues with the PL tone and End Tone for the scanner. They seem to not be working correctly. The scanner is waiting for the carrier to drop before it resumes scanning and not when the audio drops. this is happening on both conventional freqs and the Knoxville TRS I monitor. I am still trying to figure this out.
I live in Cester County, TN, some 50 to 60 miles from Memphis. Reception of the Memphis system was poor. After the update it is much improved and I can monitor day and night. The volume is more even with other systems monitored.
Also, Lexington, TN, which is relatively close by, transmits some in digital which was easily decoded by my BC785D, but not satisfactorily with the 996. Now, it is very good. Same situation with TWRA. Previously, the 996 could not decode but the 785D did.
