Re: Baofeng microphone mod for BITX

It showing you where the push to talk connections are which is basically the grounds of both mic and speaker connections that are connected together when you press the push to talk. So yeah basically pressing the push to talk will combine the mic ground and speaker ground. I am not sure if that will cause conflict in the radio.

Despite the posted diagram i'm still not sure how to wire up the unmodified Baofeng mic to the Bitx.
the speaker connections seem obvious, with ground on the sleeve of 2.5mm and other speaker connection to tip.
the mic + connection seems fairly obvious too , on the ring of the 3.5mm.
But where are the mic - and PTT wires from the Bitx connected, and do they all use the same ground?
Which Bitx wire connects to the tip of the 3.5mm (v+) ?
