The K7ICU repeater is located at the base of the Catalina Mountains about 350 feet above average Tucson terrain. It is an open system providing coverage to the greater Tucson area. Backup battery power is automatic during a utility power outage (linked repeaters do not have backup power at this time).
The system uses delayed/COS gated receive audio, reverse phase burst CTCSS (Motorola 120° phase shift), a CTCSS dropout timer and a squelch tail hang timer to eliminate squelch noises on any tone squelch enabled receiver. CTCSS is also not encoded during voice or CW ID and DTMF tones will not pass through the repeater. Use the DTMF Regenerate function (see DTMF Commands) to pass DTMF tones for paging or to command a linked repeater.
