North Shore Radio Club

UHF repeater also used for SKYWARN: 442.725+ MHz located on the far north side of Chicago. DMR (digital) users will need to use color code 1.  Digital mode supports 2 simultaneous, yet unique “time slots” or channels. Slot 1 users will use Call ID 1, slot 2 users will use Call ID 2.  If an analog signal is received by the repeater, an analog will be transmitted out.  If a digital signal is received by the repeater, a digital signal will be transmitted.  If you are strictly an analog user and do not wish to hear the digital hums and squeals of a digital transmission, set your analog radio to use tone squelch frequency 114.8 Hz.

The repeater consists of a Motorola MotoTRBO repeater operating in mixed analog and digtal mode and uses an S-Com 7330 controller. It operates with about 80 watts ERP from an offset pattern antenna at 513 feet. It primarily covers Cook and
Lake counties and has become one of the most active repeaters in the Chicago area.  The 442.725+ repeater is also connected to Echolink courtesy of AA9VI.  The node # is 7641.
