They may not be going digital, but they're moving away from the radio it seems with the new IRIS system and P1. Welshpool just got in trouble for not giving a radio turnout message and 6AR said "At this stage, we still require a radio message."

CFRS and VFRS may switch to other options for routine messages and status updates, but at the end of the day, most of the "interesting" traffic will remain audible on WAERN.
