Anyone know what the transmitter FM deviation is for "out of the box" MXT275 micro-mobile transceivers in "repeater" mode on channels 15-22? Is it the +/- 2.5 kHz (narrowband) FRS deviation, or a more typical +/- 5 kHz (wideband) GMRS deviation? I know the MXT400 transmitter FM deviation can be set via programming cable, but haven't seen any discussion on the MXT275. The MXT275 manual is silent on such matters.
