A repeater is under control of the licensee who’s call sign the repeater uses. I only control my transmitter. There have been ham trunking systems pop up for years, mainly as a curiosity or experiment I suspect.?
I think this is the right approach.
The whole concept of a repeater was once a novel concept that, as I understand it, hams had to struggle with the FCC over. Retransmitting someone else’s signal? From an unattended, remote transmitter?! On a mountain?!
I’m not convinced that transmissions being spread across one of a small, discrete set of frequencies is a significant barrier. It’s certainly more straightforward and easier to monitor than FHSS. I think such a system would be well in keeping with the history and spirit of amateur radio experimentation.
