[Kenwood] TS-850 M/Ch control

[John Pinkston]

	The detented control labeled M/Ch on my TS-850 is malfunctioning.  If 
one click moves the channel up, the next click moves it down. No matter 
what direction the control is moved in, the ups and downs alternate.  I 
suspect the control itself, but since the radio is otherwise working 
fine, I don't want to open it up until I have a replacement part.

	Has anyone seen this before?  Is it the control or something else?

	If it's the control, where do I get a replacement part?

Thanks

John
