So at one point in time I was hearing a ton of activity from several talk groups such as Moore, OHP troop A. However recently I have mostly been hearing Cleveland SO. My guess is they were doing some testing and it isn't finished yet. I am in Norman and listen to the Norman site. One thing I have noticed is all of the other sites have a primary control channel and Norman does not. I am using a Bcd536 hooked up to my roof antenna. Is it just me or what? I hope I explained that right. Thanks
