[Elecraft] K2 and installing KSB2 & 160m

[Matt VK2RQ]

I just installed the KSB2 module by the book, and it worked no problem. One thing you may want to consider is the UNPCB microphone adapter kit, which lets you easily re-jumper the microphone socket on the K2 to make it compatible with different types of microphones without having to break down the whole radio. I didn't see a need for this flexibility in my particular case, so I didn't bother with that option, but if you may conceivably use the K2 with different microphones, it would be a nice feature.

If you don't get the mic adapter, and you use the Elecraft MH2 microphone, you can just jumper the standard headers directly across with the jumpers provided in the kit. If you want to use a different microphone, then there is a nice hack where you use a computer connector to make a jumpering block that lets you make connections without wire wrapping or damaging the microphone jumpering PCB headers on the control board.
