Well, then you have a radio problem! can't tell you what it is as it could be many things that are causing it. You are sure the antenna is still functioning as it should?

I have seen a funky microphone switch do this. It keys the radio but does not switch the audio from the mic element. What microphone is it? Maybe just need to clean the switch contacts with some deoxit or wd40. If it does the same thing with a different mic, then the problem is probably in the radio.
Should see a TX light, if not then you are losing TX (LOCK) and so the meter falls to Zero, no Audio in Talkback and it's trying to go into RX mode, but you don't hear it because the TX mode is not locked - to the PLL to produce RF so you can send RF, but the TX mode is enabled, so that shuts down the RX side from even working - on top of; if you have a radio that needs Speaker Return - it's (Microphone Key switch) not there to enable the internal speaker to work (Plunger is in, versus being out sort of thing)- so it sits silent, looking back at you.
You have to figure out why it's not staying in Transmit.
Could be many things including a a power supply regulation issue - it's in shutdown mode. May be not the main one, (13.8V) it's the regulated 8V one inside that is shutting down.

Newest update::: so different mics didn’t change a thing. So still mid sentence radio goes silent and needle goes to left however my friends still here my transmission. And yes does it with amp on or off. Some days are worse then others.I believe it’s just old school talk back trucker mod . Please help? Any ideas?
Not sure if I'm just not seeing it or it just hasn't been listed. What radio is this happening on?
