my yaesu ft2200 has a sticky ptt switch on the mh-27 mic. upon inspection, it looks to be a tired return spring. finding a replacement for it has been trying. i did find a wireless model mw-2 that is a direct replacement. but, at $80, that's more than i paid for the radio. if it works, that's great but i've never used a wireless mic before. i would like some input as to the performance before i drop that kind of cheddar on a mic. who here has used one of these and how do they perform? thanx.
