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,

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. 73, Dave, W8FGU On June 12, 2020 10:02:15 "hawley, charles j jr" <[email protected]> wrote: 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?
