Chuck,
If you want the VFO switching capability with the up and down buttons on
the MH4, you will want the jumpers installed for the UP and DN function
on the header also. If you look at the KSB2 manual, it just says to
install all 8 jumpers for the MH2 (and now MH4).
I do know some ops who have built an adapter to fit the 8-pin mic
connector and is placed in between the mic and connector. They then wire
the adapter to match the mic they are using. Probably more work than
just removing the Front Panel though ;-)

Ah so...
That's going to take some disassembly. Disconnect the battery. Remove
the RTC and unscrew the control board and pull the front panel off I
guess. I just looked and need to install the 5 volt jumper and then the
resistor. I finished building this 10 years ago so I had to get out the
assembly manual 🙂
Thanks for the info,

Subject: Re: [Elecraft] MH4 Mic on a K2?
Hi Charles,
Bias for the MH4 (and previous MH2) mic is provided by placing a 5.6k
resistor between pin 1 and 6 on the mic connector of the K2.
Most of us just solder the resistor to those pins on the back of the
mic connector on the Front Panel Board. My MH4 came with a small
envelope that contained a 5.6k resistor and 8 2-pin jumpers for the mic
config header. The UP and DN buttons on the MH4 switch between VFO A
and VFO B on the K2. It switches bands on the K3, KX3 and KX2.

The Elecraft manual says the condenser type MH4 mic is acceptable for
use on the K2, but I don't see any bias for it in the K2 or SSB2
schematics. I never had a mic for the K2 so I thought I'd get the MH4
and maybe use it on my K3s as well.
Am I missing something? Is there bias for it on the K2?
