Just a note... Trunked is digital. Some have digital control channels with analog voice channels.

You can check out http://www.radioreference.com/index.php to see what type of systems are around your area and/or just google for your area.

The only problem is if the local police/fire use encrypted trunked systems. There is no easy or legal way of getting around this. Even 'tho the local police went to this, they still use the old open frequency for normal traffic. They seem to use the encrypted when handling sensitive information.

I still use the scanner to listen to police, local hams, and the power company. The last two are good in bad weather.
