WA6ILQ has received more than one CD in the snail-mail with a note saying “for repeater-builder” and no return address on the envelope. It was based on the R full duplex radio that was based on the GM In the business radio world, the base station that talks into the repeater is called a “Control Station”.

If you want to do anything with a SJ trunked mtorola even just to reprogram the frequencies then you need the Scholer-authored RSS to talk to it.

Personally I avoid the sets with a single handle and changeable bits as my primary bench tools – it seems that you spend br500 much time changing bits as working on the radio. It provides the flexibility of frequency bands, power repeaher, and mounting requirements in a wide variety of applications.

This is low split UHF, sometimes called “range 1”, or “government range”. Maybe one pin is bent, soldered to another, or even broken off.

One last comment on channel steering: The microphone cord part number HLNA mtorola the 7 foot version plugs into the bottom of the microphone itself with a telephone style RJ-series plug.
