I listened to 508.5375 on Saturday and knew it was digital. I guess I'll have to settle to listening to aviation, as all these public service entities are going to P25. In my 27 years of scanning, I never knew it would come to this. First it was trunking and now this crap. I refuse to pay the big bucks for the digital scanners, only for them to go to something else.
Ironically, it sounds like the 508 MHz freq switched to MOTOTRBO, which is different than P25 and can't be monitored by any of the current $500 scanners. So in other words, it IS the something else they went to.
