Hi , I installed Ubuntu 14 and setup gqrx and then followed the guide at OP25 For Dummies – Or how to build a police scanner for $30 (Part 1) | John’s Tech Blog to setup OP25. Seems like OP25 is working great but I only get 1 transmission worth of audio at best then it's silent when I start it. I know it's capable of working because I can hear perfectly clear audio on the P25 LSM system I am monitoring but I can't get consistent audio. The system is a P25 Phase 1 system VHF LSM. (Hence why I'm trying SDR...) I have tried different flags but I don't appear to have it right. Can anyone provide some insight on this. I am seeing all of the talkgroup id's go by and specific radio id's when there is traffic but for some reason the audio just isn't working consistently.
