I'm trying to program the TX DPS and am not having much luck. I live in Dallas. I use WIN500 and have programmed in "CONV Objects" all the APCO-25 Statewide Channel plan as well as Dallas Regional frequencies along with TXCALL1 and TXCALL2. I have set up the Squelch Mode for P25 frequencies as: NAC and set the Modulation as: Auto I have a 30ft high discone base antenna as well as have tried a rubber duck and am not receiving anything. Any suggestions? Thanks.
