Radio only needs rebanding support for most MOT 800 systems
You only need a radio that supports rebanding if you are monitoring a MOT 800 rebanded system AND any of the voice frequencies fits the format of 85x.xxx0 MHz. With EDACS or LTR, just program in the new frequencies.
PRO-163/PRO-164 supports rebanding
PSR-400/PSR-300 supports rebanding (they are the same as '163/'164)
PRO-2055 does not
PRO-96 supports rebanding if you have new enough firmware
Don't forget there is also the PSR-410 & PSR-310 now, which are upgrades to the '163/'164.
