Hello, I have had a few scanners and currently have a RS Pro-92 that I use to listen to Prince William County fire dispatch, Davison Airfield, Dulles Airport, Reagan Airport and Manassas Airport. What I'd like is a scanner that I can expand my FD listening (be able to hear all Prince William County fire, Fairfax County fire and Fort Belvoir fire) as well as the 4 airports above. I am currently looking at the TRX-1 by Whistler, it appears to do what I'd like it to do. But what I can't find is how many banks/channels it has and will I be able to set it up to scan PWC in one bank, FFX in another bank, etc, etc? Also how hard is it to program? Thanks for any help and input?
