RS22 RadioDitty Hand Mic

[Wagon529]

I added this speaker mic to my order when i bought the GM-30 Plus couple months ago.  I have had issues with the microphone sounding like i am talking through a rag.  Is there any recommendations for an upgraded, better quality speaker mic for this radio.  thanks

I had that same unit, and got low volume feedback on my signal checks as well.

(I also hated the spring clip actuator).

I returned it and went back to using my cheap little Retevis unit.

A lot of people drill out the tiny hole in front of the microphone on those speaker-mics.  Sometimes they’re too small. Sometimes they’re plugged.  We even had a guy on a net who had plugged his accidentally with food.  We could hear him key up but nary a word of speech.

And then you get the people who drill out the hole, going too deep, right into the diaphragm on the capsule. I've had to fix dozens of handsets, both in the audio and radio world for people because of their attempts to do this heavy handedly. It's usually best to open it up, pull the board, then drill.

Sometimes, simply using a countersinker and putting a bevel on the soundhole entrance does better than enlarging the hole. And for some of these radios, it's not actually the hole *size*, but that the cheap plastic castings are out of alignment with the capsule entrance hole.

I took all the KMC-21a and KMC-45d handpieces and replaced the Kenwood mic elements with Panasonic WM series for higher sensitivity and resolution. Use the elements that Pana makes for multi-track voice recorders or high-res capture handhelds and it sounds 1000x better.
