[Scan-DC] AA County-system tests

[bobjeter1]

Were conducted most of the afternoon today on several channels. One  
problem alluded to was the one second delay programmed in the  
poratbles to drop the carrier after the key is released. The  
dispatcher often starts talking before the carrier is dropped causing  
problems.

Another was the "up and down audio" noticed on some portables but not  
others.

On an active channel a policeman inquired if he had missed a call  
because at a certain spot (Cafe Mezzanote and Rt 2 in Arnold) the  
digital went out an d he couldn't receive anything for a brief period.

Sounds like the "big M has some tweaking of their own to do and it's  
not all in our scanners.

The Uniden procedures for tweaking AGC values and P25 optimization  
have done a lot to improve audio quality on my BCD 396T. It's analog  
quality with a good signal. I use a Motorola amplified speaker which  
has a lot of bass emphasis which also improves audio quality. Much  
improvement was noted also on USNA and Queen Anne's county systems.  
The BCD 396T settings are universal.

Some very short transmissions fail to decode at all but that is not  
too frequent.

Happy listening, Bob
