Standard EDACS is analog, PROVOICE is a digital option on EDACS systems. However, don't pay extra for EDACS to listen to AEP, because as phask mentioned, the AEP EDACS system is being retired. AEP's new system is P25 digital, which comes standard on any digital scanner.OK Tkx - I see AEP uses an EDACS but is that the same as ProVoice EDACS? (My guess is not)
The only NXDN I see is what seems to be a towing company R.E.M.
