I found this inexpensive Chinese copy of the venerable Yaesu MH-48 mike on Amazon for $14.99. At that price, even if the mike doesn’t sound as good as the original, you could open it up and pull out whatever replacement parts you need on your original mike, and throw the rest away! Turns out that it actually sounds pretty good. I bought one to try out on my TYT TH-9800 because I’m not too keen on the mike that ships with it. Oh, it’s not horrible, but if you’re going to make a clone of a Yaesu radio, why not clone the mike as well?
That’s basically what this mike it–a true Chinese knockoff, right down to the “Yaesu Musen” small type and logo! It pretty much feels like the MH-48 on your FT-1900, FT-2900, FT-8800, FT-8900 and etc. The only difference I’ve found so far is that the PTT switch doesn’t have the nice tactile feel that the original does. This one’s kinda squishy, but not horrible.
Anyway…if you’re going to try this out on your TYT radio, you’ll be disappointed to find that the PTT button doesn’t work. Yaesu mikes run on 8 volts, and the TYT runs on 5v. So, you have to open up the mike and parallel a 100 ohm resistor across another, then it works fine.
