Hello Gil, I used Icom HM36 with KSB2 before and it worked well. HM12 and HM36 are electrically the same. For wiring, please follow Don's suggestion.

Gil, I have not used one, but there is not a lot of difference in microphones. There are basically 3 types, the Electret microphones (which need a bias resistor), and there are high output dynamic microphones (most Kenwood mics are in this class), and thirdly are the low output microphones such as those using the Heil HC4 and HC5 cartridges. The first two classes of microphones work well with the K2, but the low output types do have problems on some bands (particularly 12 and 10 meters). Other than the class of microphones, there is the matter of the microphone plug pinout. My strong recommendation is that you change the wiring of the microphone plug to the Elecraft pinout even though the K2 has the mic configuration header which can accommodate most any microphone plug pinout. By changing mic plug, you have a microphone that is dedicated to the Elecraft mic pinout (no longer Icom). Icom microphones are usually of the Electret type and need a bias resistor. If you need additional information on microphones and their wiring, go to the website of G4WPW. He has compiled a wealth of information about ham microphones.
