Hi I have a TM241A 2 meter rig and the stock mic has an intermittent problem. It would seem to be intermittent power wire or ground wire, as all functions cease when it craps out. I have not been able to isolate anything. It has always started working before I got too far with it. I sure could use a schematic of this mic's circuitry. Can anyone help out? 73 Michael NØXY
