Do I need a tap for a 996XT or PSR-500 to do this? Sorry...new to unitrunker.
I hope you are right. A little bird also told me that this 700 system may be a replacement for OpenSky and be merged with a VHF system on the Northern half of the state....
Your PSR500 has a built-in discrimator tap, the same connection you use to program with the PC. Set UniTracker to "inline."
Be assured, OpenSky will EVENTUALLY be discontinued, and all PSP vehicles are being outfitted with dual-band APX mobiles in the VHF/700/800 bands as they are brought into service. This could be YEARS down the road. OpenSky is proprietary and is overall a failure. They'll phase the product out and eventually stop supporting it.
