I provide the live audio feed for Chesapeake PD East and West. Some time ago I had to abandon my Pro-96 and swtich to a Pro-106, because the Pro-106 seemed to be less susceptible to hanging (which I guess was caused by that Greenbrier digital repeater problem that someone mentioned in another thread.).
I had also noticed that scanner/antenna positioning seemed to be much more critical than it used to be. When I purchased a new Pro-197, I thought it wasn't working, until I moved to do a different spot in the house, then the Chesapeake signal was fine. I never remembered this being in issue when I first moved to the Great Bridge section of Chesapeake.
