Mic suggestions for K2

[Eddy]

So guys, I'm not digging the Heil hand mic I bought from Elecraft way back when......it works, but I've never ever receive rave reviews for ssb audio, always getting complaints about it sounds muffled!!

And yes, I've been working with Gary and followed his expert suggestion to adjust FL1 and little bit higher in freq than FL2 and it has helped but most of my ham buds like my ICOM 746pro waaaay better!!

So.....maybe a different mic could help? Any suggestions?

As always, ths forum is the best!!

Ed,

I would guess that it sounds like it has too much bass, and I don't
think a different mic will make much difference - unless there is
something defective in your mic.  See if you can find another Elecraft
MH2 and give it a try before making a final decision.

The bass response of the KSB2 is quite low.  You can reduce it by
changing the value of two capacitors on the KSB2 board.  Change C34 to  
0.47 uF and change C32 to something in the range of 0.003 to 0.005 uF -
I use 4700 pF capacitors for C32.
Those two changes are easy to do and not destructive, so if you don't
like the effect, you can always restore the stock values.

I like the MH2 in that respect and get good audio reports. But the PTT spring is way too stiff for me :-)
