[Ed Purvis]

Other than the button noise, any other comments on the 703 mic?

Bob -

The Vaseline on the pivot helped a lot.  The noise is still there, but I think I can live with what's left.

I may try some of Stuart's padding suggestions.  The noise is from the button and not the switch and padding out the pivot point and where the sides of the button brush the case would do the trick, but there is little clearance in either spot.

Thanks for the help, Bob and Stuart.

Found that if I carefully opened the case {watch for spring loaded parts} by removing 3 screws in the back, and using Vaseline to lubricate the PTT button pivot at 2 places {front and back half} and the tip of the bar that activates the switch the issue is corrected.  A flat toothpick is ideal for applying a very small amount of the lubricant.  I don't advocate using any type of spray lubricant under any circumstance.
