SO, you can use a wide variety of used and surplus microphones (Public Address, LandMobile, CitizensBand) ..
as long as they are ~ 150-600 Z impedance and you properly wire up the 8-pin circular (Foster) microphone connector.
That proper wiring is in your TM-241A Owner's Manual
The Kenwood MC-43 is their common hand microphone used on many of their radios (and has 8-pin connector already installed).
IF you desire new (currrent production mike) then the Shure 527B hand microphone is a good choice.
You want the "B" version, NOT the "C" (carbon) version.
The Shure 514B is another option. The Shure 527B and 514B will require installing the 8-pin circular microphone connector
DO a GOOGLE search on that Shure product name -- and you will find hundreds of sources -- even the Guitar Center retail outlets!
IF you desire a DTMF microphone OR a special featured microphone that was shiped with the radio --
THEN the search becomes longer to find a used microphone OR repair one that is damaged.
