I thought the USRP_TX app was only for that hardware. I want to use a conventional radio, just as you described, for both P25 and NBFM. So sign me up as as experimenter wanting to try that!

> Hi Folks, new here.. Did a lot of looking around, but didnt see the answer to this. I want to use app_rpt as my repeater controler and support P25 + NBFM. I see a rx-to-asterisk app here, but not a corresponding asterisk-to-tx app. I saw a repeater app but didnt appear to support asterisk. Am I missing something or does it not exist? Thanks!
