Somebody missed the earlier thread that ended up in heated dispute. (;->) They've been mostly but not all units encrypted for eeehhh... about a year now. Oddly enough over the 4 July weekend all units on both channels were clear.
He didn't say he wasn't sure. He said "I believe". More than likely everything he hears is encrypted. FuelForFire said the same thng. And I agree with both. When I monitor them, everything is encrypted, but that's not to say that I, or we, may miss something that's not.
