Dual repeater setup project

[Jay G.]

Current setup is a UHF to VHF crossband repeater using 2 gm300s and a rick.

we want to make a true UHF to UHF machine, and also interface it with VHF both ways:

All UHF portables will TX on 468.XXX and RX on 463.XXX
We also use 154.XXX simplex which is main dispatch.
We want everything from the UHF machine to be then retransmitted on VHF, and everything from VHF to be transmitted on the UHF repeater.

Can someone help with pin wiring??

Thanks!

Assuming the UHF repeater is going to be RICK-controlled, you can make this cable and connect it between J2 on the RICK and the accessory connector on the VHF radio and get the operation you want. Fair warning: there won't be any hang time in cross-band operation and the audio going either way isn't going to sound real great since J2 is just a pass-through connection that doesn't send audio through the RICK's audio processing. Of course, you could also get another RICK, set it up for cross-band operation, and use it in place of the cross-band cable.

If this is going to be for any kind of mission-critical app, I have to recommend that you invest in a real repeater for your UHF channel.. even if it's a second-hand MSF, MSR, or even a Micor. GR-style repeaters using Maxtrac/Radius radios as transmitters just don't have the duty cycle you want in a mission-critical environment. Don't forget about narrowbanding, too.
