What is your node structure at the repeater and hub ends of the link? In other words, how is the repeater end of the link tied to the repeater, as well as the hub end of the link?

It seems to me that both ends of the link cannot be full-duplex because they will feedback on themselves. You may consider full-duplex at the hub end, and half-duplex at the repeater end of the link, where the hub is the master, and the satellite repeaters are the slaves, but each repeater itself operates as full-duplex.

Curious... what are you using for radios for the link portion of the system?

Thanks,

Hi guys... I am in the midst of deploying a 5 site system. All of the sites with the exception of my own will be using link radios sitting on the repeater pair, some sites do not have internet access so this is the only option. Each node will be permalinked to our hub.

What we discovered when we brought site number 3 online was the dreaded "ping-pong" effect, and I did some digging and found out about the rxondelay parameter, that seems to be the place to start with this.

The other option we are considering is dropping the hang time off each repeater and using app_rpt to do hang time and courtesy tones instead (duplex = 1 instead of 0) but not sure that would work real well or be optimal.

Anyone have any experience with a setup like this that can offer some advice? This is my first foray into this unfortunately, I've always just interfaced the radio or repeater directly to app_rpt in the past or through a controller so it's been a bit of a challenge.
