Hi,
Keep in mind that receiving St Clair trunk groups isn't as easy as just programming a scanner because the county is simulcasting their transmissions. All of the digital scanners have problems decoding this type of system unless you happen to be in just the right spot. The reason is that in a simulcast system our scanners will receive multiple signals with the same information on the same frequency, but each a few microseconds apart which causes data errors our scanners can't properly process. The result is usually the voice is garbled even though you have 5 bars on the signal meter. The way to overcome this issue is to either live in a place where most of the signals are blocked or else you use a yagi antenna and aim it at only one tower.
The amount of radio traffic in this area has also dropped considerably over the past couple of years as more and more dispatching and routine radio traffic has moved to computer-aided dispatching via their in-car computers. There's also been a greater use of cell phones by police and fire personnel in order to keep conversations more private.
It you do buy a digital scanner it will probably be the last one you'll ever buy due to the changing communications technology. Although most dispatch channels in this area are still broadcast in the clear, many other police and fire agencies are moving toward systems that use full-time encryption. It's only a matter of time before they all do this. Also, given how much is now done over their in-car computers, their voice radios are becoming less important.
Thanks!
