[Elecraft] K3 hand mic

[Bill]

When I bought my K3, I also bought the hand mic. I used it for a few 
weeks until I tired of the comments about the mechanical noise it made 
when keyed. I had to be very gentle and careful when using the PTT so as 
not to have all the keying noise on my signal (cheap mechanical design 
to activate an even cheaper switch). I elected to do surgery on the mic 
and gutted the mechanical switch out completely. I then did a little 
Bondo work on the shell and installed a square Heil PTT switch. It works 
and is very quiet. The only problem is the switches only last a couple 
of years - which I learned from using other Heil mics). If you are 
careful, you can open the switch and put a little DeOxit in there and 
all is well again.

All that said, my question: Any suggestions for a hand mic that will 
work quietly and last forever?
