Hi Paul,
Click on the
Database link at the top of this site and then drill down to West Virginia, then the county you want (or Statewide if you like). Click
here for WV State Police freqs.
You'll find all the frequencies you'll need in the RR DB.
As for programming the PSR-500, you should consider purchasing Win500 (
http://www.starrsoft.com ) or PSREdit (
http://www.psredit.com ). They both have free trials. Download them, install them, try them out. They are great programs to use for programming your scanner.
Of course, if you really want to make best use of the data in the RadioReference database (such as importing whole working trunked systems into Win500 or PSREdit to upload to your scanner), then you'll need a
RadioReference Premium Subscription. I don't know what the going rate is, but if you really want to make it much easier to program your scanner with the trunked systems you want to listen to, you'll want a Premium Subscription.
Note: A Premium Subscription is not required to just view the RR Database and make use of the frequencies you find. It is only needed if you want to be able to access the DB from within PSREdit, Win500 or ARC-500 to program your scanner.
Anyway, get some of those programs and familiarize yourself with one of them. That's the best way to do it, and most people who could help you would be counting on you using one of those programs.
Other than that, also do a search on these forums. The PSR-500 is widely talked about here. It would pay for you to start reading the existing threads about the PSR-500.
