Baofeng Radio Beeps but Won't Transmit - Easy Fix

If your Baofeng radio isn’t transmitting but simply beeps, even though the LCD works and it can receive signals, the issue is simple:

The battery supply voltage is too high. The radio has a safety built in that prevents transmission when voltage is above 8V. This is to keep the transmitter from burning out.

Maybe you are using lithium batteries. If so, replace one of the six batteries with a spacer/dummy so that you’re running off of 5 batteries. It will then work. NiMH batteries run at 1.2-1.3V so those are fine, but Lithium can trigger the transmit disable function.
