KMC-59C Desk Mic Keys Itself

[dispatch235]

So I have a new KMC-59C desk mic that I hooked up to my NX-3720 and worked fine for a couple of days, then a few nights ago the radio keyed up by itself... pushing and releasing the transmit button would not release it, so I unplugged it and radio unkeyed. Plugged back in and was fine then a couple hours later same thing happened, keyed up the radio by itself. I switched it to a TK-7180 and it happened again but was almost a day before it started.
I've opened it up and inspected the switches inside, the plug on the cord seems fine... I've never had any problems with my KMC-9C's on these radios, It is strange because i can't find anything physically wrong with this mic... I have searched and not found any reports of problems with this model, just wondering if anyone else has had this happen and figured it out.

1 yr warranty on it. Take it back to your dealer and get a new one.

Yeah, it was part of a surplus purchase with several radios, etc but was still in box and never used. Thanks

I've had a KMC-59C sitting on my desk connected to an NX-900 for about 13 years now. Never had it do anything like that.

This may be a tough cookie to fight with but take it to you local dealer to see if they can get the date code of it and try to warranty it.
Otherwise, bad in the box. Not a common issue, talked to several people up stream, they said if it can be warranty replaced, do it, if not, out of luck.
