I've picked up Devault 800 from Pottstown before with my G5. I've noticed a variance in sites received at the same spots. From Eagleview in Chesco I've gotten both Devaults, Morgantown, Hibernia, and even Pocopson. Last week heading to and from Shady Maple along 322 I even picked up Red Lion and Reeser's Summit 800 sites. From home in Drexel Hill it's mostly Philly 800 and occasionally Philly VHF depending on which CC it locks onto.
In terms of traffic most of what I get is PGC and with some Penn DOT. It seems like not all of Penn DOT District 6 has switched over as I've mainly only heard the Montco channels with a couple test counts on the main Philly channel. Hopefully by the time we get our first snow storm they'll all be switched over. I've also noticed the safety patrol tow trucks don't have any antennas on them other than the stereo antenna so not sure if they're no longer using radios or just in the process of switching out.
