TYT TH-9800 Mic Pinout
I’ve been thinking about the possibility of using a different mic with my TYT TH-9800 Quad Band Transceivers for a while now since the main issue I have with the radio is how hot the mic input is. It’s terribly sensitive and will over modulate my audio unless I rest the mic in my lap. This doesn’t sound like a big deal but since I use a whole bunch of different radios I do forget from time to time and blow someone away by holding the mic close to my mouth as I would any other radio.
Here’s the official mic pinout from TYT. The diagrams listed on most sites are completely wrong and many even show an 8-pin RJ-45 connection however this radio has never shipped with anything but an RJ-12 6-wire modular connection. I’ll be making an adapter cable to see if I can get a Yaesu DTMF mic or Icom non-DTMF mic working with this radio in just a day or two. If neither of those will work I’ll look into Kenwood and other brands to see if I can find one that is compatible with the TYT radio. I’m willing to give up DTMF functions for better audio right now since I can always swap out to the original mic if I need any rarely used DTMF commands, besides most of my DTMF use is mobile and there will be a Kenwood TM-V71 finding it’s way to my vehicle soon. 🙂
