This morning I heard radio techs doing their thing (without encryption obviously). I wish I could list the TG, but I was in the midst of hooking my latest 536 to my main radio cabinet multicoupler and was tweaking the programming, and erased the recordings (sorry). I believe I saw "P10" listed as the description (instead of P25). The audio was so pristine, I find it hard to believe that there was more than one site transmitting on that frequency. Just by gut instinct and experience, it looked / sounded like a White Tanks transmitter, alone (for now) The signal was full scale, solid. I have zero doubt that it will be as they call it, a simulcast, and maybe it was today, but the 536 was clearly just getting data primarily (at the least) from one tower. And my feed point is about 30' above ground. Just sharing the marginal information I saw / heard today.
