Can the current generation of scanners, such as my PSR 500's and 600's, demodulate the TDMA Phase II systems? In the past it seems like we can't listen to Riverside County after they have updated to a new system, until a new scanner model is on the market some time later.
I remember visiting Riverside County back in the late 80's and early 90's when I had an 800 MHz receiver and a trunked scanner did not exist. I tried to listen conventionally but Riverside had put an "anti scanner" tone at the end of the transmissions that would delay your radio from moving on to another frequency with the goal of keeping from being able to track any one incident. The systems users didn't hear any tone and there was no delay for them.
