Transmission1

Hey all been out of the game for a fair while. Recently got. A whistler trx-1 just after some local frequencies. Dmr Ect? And another question is does the prison still use radios or moved to tetra at all?

Many thanks and looking forward to scanning again

Some prisons still use analog.
450.5-450.75 & 460.5-460.75
452.5-452.75 & 462.5-462.75
— seem to be the new bands, but that's just based on the few I've found, not any official list.
