Lyle Is that rear panel mic jack a true tip-ring-sleeve jack or a simple mono jack? If simple mono, I'd be uncomfortable putting a stereo plug into it. Too many folks have had trouble with the K2's headset jack. I'm a bit leery of small jacks in general due to the small leaf springs in them. 73, Bob N6WG
