DISCO32 refers to this as a Pork Chop Sandwich and it’s a great name. For those of you unfamiliar, handset microphones for radios have been called “pork chop” by the troops since at least World War Two.
Featuring an omnidirectional microphone, the Modular Speaker Mic (MSM) is tailored for first responders; including fire, public safety, and military radio users. It’s adaptable to a wide selection of radio models from brands like Motorola APX, XTS, L3Harris, and Kenwood.
Engineered to accommodate headsets with dynamic microphones and U-174 type plugs. This functionality enables users to effortlessly switch from a patrol configuration to a tactical setup, facilitating quick adaptation without modifying the existing communications setup.
I like that it is also compatible with major tactical headset brands such as Otto Tac, MSA Sordin, 3M Peltor Comtac, and Ops-Core AMP Communication Headsets.
Having used this extensively, I will tell you that its 90% there. Im surprised the idea hasn’t been attempted by others. The unit is large. I believe its large to accommodate both the large PTT on the front and the PTT button. Having both there requires alot of space. The big button is unnecessary given the presence of the better protected side button. The large button is the root cause of repeated accidental key ups. Ditch the big front button. Make it smaller overall and its a knockout.
