There is nothing to figure out. Yes, they use an EDACS ProVoice system and yes there is no scanner that can decode ProVoice and probably never will. The digital mode ProVoice is proprietary and it is unlikely that it will ever be licensed to scanner manufacturers. Monitoring ProVoice systems is still possible using various methods.
Yeah, I know this thread is old but I just wanted to pass along.... I just ordered a PRO-96 A model to go along with my BCD396XT. As soon as it comes in, I'll be able to start my new project...mapping it out, then start listening with DSD
fyerman01, were you able to pick up stpso? if so what is the min. required scanner to pick it up, etc etc? I haven't listened to them in years. My old scanner picks up the freqs in the DB but I only hear static and jibber. lol thanks
