As you can see, construction of the control board is just about completed. All top-side components have been installed, with today's stuffing of all the integrated circuits. What remains to be installed are 2 capacitors on the bottom of the board, which are a circuit essentially added to the board design to provide improved keying shaping; but I ran out of steam to do that task this evening. |
The other thing that held me up today was the pictorial of the underside of the board where these two capacitors are to be installed. If you have a look at the top right corner of the board, you can see the resistor network RP2 installed in its rectangular outline on the board. Just to the left is a round solder pad with the ambiguous marking "1". The pictorial of the underside of the board implies that that is where RP2's pin 1 should go. I think the marking on top of the board is most likely correct and the pictorial probably represents some older rev. of the board, but I wrote to Elecraft for clarification.
