Looking for some advice, and parts numbers if you want to be really nice, of a way to crossband a UHF repeater into a 700 MHz trunked system. They're both p25 and I only need it to work on 1 talk group of the 700 system.

I was thinking a pair of mobiles, one UHF and one 700trunking, using a bridge to complete the crossband. I'll admit, I'm kind of an armature with this but my friends are not so I have build resources there.

Anyone know of prefabbed "bridges" or what Motorola calls them??
Also, which radios would work best? Motorola website is a pita to navigate. I looked on the kenwood side and found a tk-5910 would be a good start but I don't really care about they brand, just looking for it to function.

My search continued and it appears this Link Comm TCB 1 will fix the bill. Can some of you that are more intune with programming specs take a look. The main things I know to look are good to go.

I owned a TCB-1 a couple of years ago. Don't waste your money, it's a complete pile of garbage. It won't recognize COR logic and the VOX operation incurs significant keying delays.

I'm guessing a direct system tie-in is not an option. If at all possible, connect the 700 radio directly to the repeater as a remote base. Bridging trunked talkgroups to conventional repeaters with radio-to-radio patches will cause significant degradation in audio quality, especially going from digital to analog.
