The hardware is a Motorola MTR2000 repeater programmed to require PL on receive. This can be changed to carrier squelch by a controller command. A signal received via Allstar will generate PL so that it is heard as well.
The output of the repeater is fed to a PA amplifier for a net output to the multicoupling of 100w.
The repeater is battery-backed up 13.8vdc but normally powered by 120vac.
