I was just participating in a 2m net tonight, running off battery power, sending and receiving just fine. Then, my radio (Kenwood TM-D710G) went completely silent. I couldn’t hear anything on either receive side, turning up the volume, using the built-in speaker, headphones or an external speaker. I couldn’t even hear key beeps from pressing buttons. I turned the radio off and on multiple times, but nothing changed. I don’t even hear the power-on chirp. The display seems to function normally, and I see things happening when I receive and transmit APRS packets. I just don’t hear any sounds.
