Cross-Band Repeater Controller (NOT using VOX)

[chiwititsara]

I have 2 x TYT TH9000D monoband mobile radios (with provision for DB9 connectors, not yet built/purchased). One is a UHF unit and one is a VHF.

I understand these radios, once DB9 ports/cables are installed, can be set up for repeater use. However, the products I've seen are only for 1 x transmit radio and 1 x receive radio. In fact, I'm interested in using these radios to build a TWO-WAY, cross-band repeater.

I've tried VOX-activated cross-band controllers and been less than impressed. I would like something that actually senses the COR signal from the radio.

As far as I can tell, the ID-O-MATIC only supports 1 x transmit and 1 x receive radio.

Is there any way the ID-O-MATIC (or another controller) could be configured so I can use my two radios (1xVHF TX'ing on mid-high power and then repeating the RX out via the UHF unit at low power) to create a cross band repeater?

I'm not very pleased with the current selection of off-the-shelf cross-band-capable mobile radios. But would like to be able to have longer-distance VHF-in/VHF-out simplex communications using the TH9000D VHF mobile (on mid-high power) via the TH900D UHF mobile (which will operate at low power so I can communicate from a low-power UHF HT around the house to the UHF unit). The UHF radio will receive my low power HT transmissions and pass them out through the VHF unit, and also repeat inbound VHF transmissions out at low power via the UHF mobile back to the HT on UHF.

ID O MATIC won't do what you want. You will have to step up to a two port controller. I have used these and have been pleased with them.

Motorola RICK will do what you want for a basic repeater controller. Also K.R. nida has a great controller. Not sure if they still sell them but I have many in service.

Assuming the use case is Part 97 wideband, a UHF GM 300 and a VHF GM 300 is literally plug and play with the RICK HLN 3333 configured as cross band directional repeater and is quite robust if you turn the transmitter power down. The time savings are tremendous, but it is easier with an older computer that does MS DOS natively. You could even grab an old M208/ M216 lowband and cross band to 6 meters. Never tried, but there may be a M208 that could tune to 10 meters as well.

I have a GR300 sitting next to me for ham crossband. The UHF unit is a 10 watt radio original to the RICK setup, I swapped in a 25 watt VHF. Works like a champ. Superb audio.
