hi everyone..

I know there are some people here that are experienced with the Turbo IP site connect... I have an issue here in which I have a trbo repeater ontop of a hill and cannot communicate to the bottom of the hill. I was gonna set up a master repeater on slot 1 ontop of the hill and a secondary repeater on the bottom of the hill on slot 2, and link both of these repeaters together with IP site connect. The site has to be on the same channel and able to communicate with each other and wondered if the xpr6350 can roam between the repeaters without switching channels and wondered if both repeaters are simultaneously broadcasting at the same time? I am very confused with the what the motorola brochures are advertising and how is the RSSI is setup on the turbo portables so it can roam. Any help would be greatly appreciated as this is a tricky project and there are experienced people that have played with this.

IP Site Connect is pretty simple in most respects. The repeaters must be on different frequencies if the coverage areas over lap, this is not simulcast. In a larger system with sites spread out, you can re-use frequencies in non-overlapping sites and use different 'color codes' to help the radios differentiate between the sites.

You do not 'cross over' between slots...if you're using slot 1 for a voice call, it goes out over slot 1 at all other sites as well.

The XPR6350 has IP Site Connect capability out of the box, it's just a matter of programming. There is an IP Site Connect checkbox in the personality(ies) that needs to be checked off, and you set up a 'roaming list', similar to a scan list, with both of the repeater channels in the list. You reference this roaming list in the personalities you wish to roam...generally all of them. The RSSI threshold is set in the roaming list screen. By default it is set to -108dBm, but you probably want to set it more in the -100 range.

You can't really tell by looking at the repeater lights which repeater is the one your portable is using, as the RX light comes on even if you're not using that actual repeater. With a display radio I'd normally set the personality name to reflect which repeater the radio is actually using...have the name end with a 1 or 2 if it's a two site system, for instance. I also typically program one of the front buttons to manually search for a site on a short press, and manually lock onto a site with a long press, for testing purposes. Since you have a non-display radio, you don't really know which site you're using. For testing, you can use RDAC to confirm which repeater a portable is using by measuring the repeater RSSI while transmitting with the portable.
