TYT TH-9800: I wanted to rewrite to a post on qrz but thread lost.
I hope this helps the thinking buyer that is researching the radio.
Just purchased a quad band oct 5th it took till Nov to get here amazon said ships in 1 -3 days then you pay & date changes.
So I finally got the radio in all this time
I kept seaching reviews as I waited a lot of muffled  mic audio complaints.

I got the radio connected it up seemed good on 6m 2m70cm RX TX ok
but connected a monitoring radio up and listened in earphones.
Deep pitched audio foggy lots deviation?
Well on air op's found deep foggy muffled audio?
Now in crossband repeat the transferance audio 100 times clearer?

I was hoping to do something with the DTMF mic and tonight I proceeded .
Opened mic very cheap made mic with 3 Torx screws .
There are 4 screws holding PCB down
"Behold a mini "HT electro element in a hand mic?
I tried 2 more slightly bigger type condesor's.
So a Kenwood TM-241A condenser element from a scrap mic being best.
Has better sound audio decreased little bit better but not the best.
Im unsatisfied... TYT Fix the issue...
The manual does not cover RJ-45 plug wiring?
Another suggestion is to forget the DTMF mic connect a amplified tone
changing desk mic on it for base use tremble to the max.
Or make a RJ-45 adapter to 8 or 4 pin male connect audio, ptt, ground up.
That being said other issues:
reciving conversation and turning the other band to different channels
chops out the entire signal per turn ? The internal speaker wimpy.
The display looks good no color change in menu.
The mic cord is cheap short & slingshot's out your hand till stretched.
The FM on 10 meters is noisy and half scale of signal all day.
for $248 free shipping never would buy a 2nd radio.
Everything else works if you can get past the Froggy, Foggy, Muffled Cold-Flu
audio coming out of radio change element or attach another mic.
But as I researched I do not see a replacement mic yet for TH-9800 radios
But working DTMF mic was that the point I bought it in the first place.
PS. through some repeater controllers that are hi pitched passive audio
it helps you sound better but listen to the radio on simplex.
FT 8900 great this tyt is not same quality as a ft-8900 w/ flaws.
My tyt will be great for Crossbading. it talks a little better after changing element.
The TYT Mono band radios TH 9000 series work great!
any mic diagram or new after market mics info be appreciated !
Write it up ...
