The old 800mhz Smartnet system was converted over to mswin simulcast sites. You should be able to use the same control channel to decode in unitrunker.. Keep in mind you will be able to decode all the site data ( affiliations, talkgroups, etc), but you won’t be able to listen to any phase 2 audio. Im fairly certain JFD and JPD are phase 2. If you are using an RTL2832 dongle you can setup another VFO in unitrunker and pipe the digital audio to dsd+ My suggestion is learning a little Linux and installing OP25. Its the best p25 decoder for p25 phase 1 and 2.
