Zbitx external microphone recommendations

 

What seems to be the most practical external microphone for the Zbitx? Thinking about one for POTA or SOTA.
 

If you are looking for a solution thats POTA/SOTA friendly, you can try either one of these three options:

1. 3d print a portable microphone such as
2. Buy a cheap microphone (like cheap baofeng microphones) from amazon, snip the exisitng connector and solder a 3.5mm TRS stereo connector.
3. Go for a DIY solution such as the ones seen .?

The wiring is similar to the uBitx and sBitx radios. The PTT switch connects to ring and sleeve. The microphone connects to tip and sleeve.?

Hi there

I find it odd that the pinout of the microphone is different from all other radios having 3.5mm stereo connector.?

They "all" do have PTT to tip and ground and microphone to ring and ground. Means that I would need a adaptor to connect up my microphones? :-(

Interesting point, and probably relates to why there is a momentary transmit activation of the radio when plugging in a microphone.

Right. There is a reason why this pinout is not the normal one.
?
Would love to reroute my radio connector so that i can use my microphones without having to put a adapter cable inbetween.
