I'm able to talk to other people directly. I hear the audio on the open spot app from my static channel. I can hear myself transmit on the channel and hear my voice on open spot. I also see the led green light turn on in my radio when it's receiving signal talk on the channel, and I hear it on the OS4. I do not hear the audio talk on my radio. Seems OS4 is not linking RX to the radio correctly. Anyone know the fix?
