Good evening folks. I thought I would pass along a little information to those of you who are contemplating the installation of the K2 DSP option. First let me say that this option is well worth the price and has many features and a wide range of adjustments for all three popular modes. But I digress from the point.
The DSP unit (KDSP2) comes fully assembled on it's own pc board with two male headers, a 12 pin and a 20 pin. I will refer to this assembly as a daughter card for lack of a better term. The "mother board" must be built up by the kit builder as per Elecraft's great instructions. During installation, you mount the mother board to the control board via a couple of headers (there are male headers on the bottom of the mother board) and a standoff that you install as part of the kit. The problem that I ran into is this. The male pins on the pre-assembled DSP board for the 20 pin header are too long for the female mating header and they hold the board away from the header about a 1/16 inch or so. Normally this would not be a big deal if you only had the K2 without the 100 watt rf deck. With the 100 watt option, the speaker enclosure rubs right up against the DSP chip itself and actually pushes on the whole mother daughter board if it is installed that way. I solved the problem by cutting 1/16 or so off the male header pins on the pre-assembled board and now it mates flush with the female header. There is now about 1/32 or so clearance between the speaker and the DSP.
