Motorola Digital XTL5000 (High Power) and V.R.S.

I have an old V.R.S. Pac that I used on a Spectra, but have recently upgraded to a Digital Motorola XTL5000 High Power version. I have the control cable attached to the new radio and it appears it "wants" to turn on when I push the vrs button. I realize there is a new repeater that you can buy and program through the software, but I would like to just use my VRS. Does anyone know a way (software settings, etc). to allow it to work? Thanks

You are going to have to open the radio and make physical connections for COR. Pyramid has a compatible repeater- SVR200, take a look at their website.

Physical connections with Motorola vehicle repeaters will only work with the old PAC-RT and the PAC-RT has its own internal squelch carrier detection circuit instead of a COR input. Ever since the Syntor X 9000 VRS, the VRS mobile radio control link is all Systems 9000 serial data. The Pyramid repeaters I have seen interface directly to the control head push buttons and let the head do the Systems 9000 serial data for them.

There is the Motorola VRS SP01, VRS SP02, VRS-EP and new VRS 750. The VRS SP01 is Syntor X 9000, the SP02 is Spectra and VRS-EP is Astro Spectra and I'm not sure about any other mobiles. I seriously doubt the original VRS (SP 01 or 02) would work on an XTL5000 and I do not know about the VRS-EP (maybe maybe not?). The VRS 750 is the only Motorola one I would expect to work with the XTL5000. Gigs, you should at least look up the currently listed Motorola VRS for your radio.
