Batboard

Well, in the process of testing my Syntor x9000, I discovered that one of my mics with the hangup switch on the back apparently has a regular mic board in it. The mic is a model HMN1004B, and the board in it is a HLN5459A, which appears to be missing the little popple that makes contact with the hangup switch, like my other mic with the hangup switch has.

The place where this mic is going to go is going to be difficult to ground the hangup clip, so, what I'm looking for is suggestions. Would it be simpler to find the proper board to go in the mic, or to just find another mic with the hangup button? If so, anyone have one they'd be willing to part with?

I would even consider soldering on the popple, but I doubt I can find it as an individual part, and I'm not quite sure what material I could use to make one.

I always seem to have the strange ones...

I found this same board, HLN5954A, inside a Spectra motorcycle microphone. In that application, there is a wire coming off the back of the board from a pad approximately in the center of the board where there is a square opening in the board's ground plane. That wire has a lug which is attached to the weight/button assembly with a screw into a tapped hole in the weight.

Am playing with audio modifications for this microphone right now. Replaced the 10uF electrolytic with a tantalum on general principles and changed the preamp base coupling capacitor to a 0.1uF ceramic. That's the blue capacitor at the bottom edge of the board, not the one in the middle.

akardam,

Just run a small gauge wire from the mic hang-up clip to a convenient ground point like most of us do. Problem solved...
