Mark, OK, there needs to be a document 'How to disassemble your K2' for those who purchased the K2 already built. Sure the instructions are there in the manual, but they are spread out over the entire manual since that is something that is learned in pieces during the build process.
Try this set of instructions: ----------------------------------------------------- The process to get to the mic configuration header is to remove the top cover or KPA100 (6 screws). Next, check to see if it has the KDSP2 or KAFT2 installed (to the left, oriented vertically, behind the control panel) - if so, remove the screw located near the center of that board (if it is the KDSP2, you will have to remove the outer board first to get to the fastening screw - just pull that out of the header pins observing proper anti-static procedures). After removing the screw, you can pull the board out by moving it toward the rear of the K2. There are two screws holding the control board to the front panel - if you look down between the two boards, you will see the hex standoffs - remove the screws from inside the K2 (or 1 screw and 1 standoff if you had the KAF2 or KDSP2 installed). Now remove the 4 screws holding the Front Panel (located on the outside covers) and pull the Front Panel and its board straight out to the front. The mic configuration header is located on the back of the front panel near the mic jack. It takes more effort to put the process in words than to do it. Do it once and you should be a pro, it is not difficult. Compare the mic header wiring with the listing of common ham mics in the KSB2 manual. If you did not receive documentation with your K2, you can download the manuals from the Elecraft website as .pdf files. Be aware that many Icom mics have electret elements and need a resistor from 5 volts to the AF mic pin - this resistor is commonly soldered to the back of the mic jack if it is needed. You will have to determine the properties and pinout for your particular mic (it would be nice if they were 'standard', but alas, there is a large variety of differences). I can only help on the K2 side. ---------------------------------------------------- 73, Don W3FPR > -----Original Message----- > > I just received a terrific pre-built K2/100/SSB unit.
