Косяк Quansheng. Не работает PTT на тангенте.

Quansheng, chasing after pennies on a single capacitor, made a serious miscalculation when using an external headset. Not only does the headset speaker get hot when the radio's squelch is open, but it also prevents you from switching from PTT to transmit, regardless of the BCL menu option. It also fails to transmit from PTT when the FM radio is on. The video explains the causes of this issue and how to fix it. The video is a bit long, so I apologize in advance to viewers.
