I used an in-band link to couple two VHF repeaters together, and have a Zetron Z38A controller that allows me to terminate the repeaters transmitted tone as soon as a user drops the input. That is all it took to keep the two repeaters happy. I never did have much luck with two users talking at the same time, so that has not been a problem. With the link we have, a user would have to be right on top of the repeater to overcome the link, so still just hear one user with a hetrodyne if another user is trying to talk, the same as if they were both trying to talk on the same repeater and one was stronger than the other.

We've used in-band on-channel (IBOC??) linking to a nearby repeater for weather nets for many moons now. It has worked absolutely great for us. Sure, it's not elegant; a dedicated link is probably the better way. And, users are going to double anyway. Can't get away from that. We've not found any timing problems you refer to... Laryn K8TVZ
