Ahh... that magic Busy Channel Lock-out feature that never seemed to be available, enabled or programmed on.
In days of old ("when knights were bold") you'd have one or two guys on the frequency with high powered base stations and no desire to share the frequency. After a few "butt-head" events with the other co-channel users they'd simply jam the co-channel users off the channel whenever they wanted to talk on their respective repeater. We used to call them the "channel master types".... Tone Panels started to include the repeater user "hog timer" functions and various lock out for overtime features. All these cure-all bells and whistle features never seemed to actually make it into service. Thank god the trunking format arrived to provide a much needed measure of breathing room. cheers, s. > I have two Kenwood Community Repeaters, one on UHF and the > other on VHF.
