Which firmware version for UVK5/6 allows me to use the headset's PTT (push-to-talk) function while listening?

很奇怪的需求，但是有一个场景，骑车时戴着耳机，耳机连着对讲机，对讲机听着收音机。这时候按耳机ptt是无法发射的，但是有信号进来后的5秒，就能发射。官方固件和萝卜都是这样的设定

I don't know; it probably doesn't have a function to transmit in frequency bands that are prohibited from use.

I tested it, and when the radio was in transmit mode, the PTT on the body could be used to transmit, but not the headset.
