Introduction

The K7ICU repeater system is situated at an elevation of about 2700' (AMSL) at the base of the Catalina Mountains in North Tucson. It is an open system providing coverage to the greater Tucson area. About 100 AH of backup battery power is on site.

The system uses delayed receive audio, reverse burst CTCSS (Motorola 120° phase shift), and a CTCSS-free squelch tail hang timer to keep most receivers free of squelch "crash" noise. CTCSS is not encoded during IDs.
