Completed Controller

Just a couple shots of the completed controller circuit board mounted in the chassis

Receiver Board

The receiver board was next. I put in a picture of the stripped down receiver board just to prove I really was removing all the components from the board and rebuilding them from scratch. First picture is before I started on the board, 3rd picture is the the completed board after I rebuilt it. The connecting wires are all measured out and formed to the connections they go to when I drop the board in the chassis. I put in all 6 receiver mods with one slight modification of my own. Instead of putting in a fixed resistor to adjust S-Meter swing I put in an adjustable trim pot in place of R493 so the S-Meter could be calibrated.

Here's a few shots of the completed Receiver Board installed in the chassis.

Synthesizer Board

Finally the last board. Here are some before pictures of the synthesizer board. This was the most difficult board to do. There is copper on both sides of the board, the copper on the component side being a ground plane covering the entire board. The through holes are also plated. It was very difficult getting the old parts off the board but I got them all off. Couple parts were destroyed in the process and had to be replace, mostly the .1ufd glass caps. I replaced all the coax lines with a much better quality coax. I did not install the mods on this board as I wanted to see if I had the synthesizer radiation problem first (and I do a little bit but still haven't put in the mods). One of my mods was to install a board mounted switch in place of the wire socket on the board that puts it into test mode. Also, the original builder apparently substituted 5 of the transistors on the board, possible during troubleshooting attempts. However, small signal AF amp/switch transistors were substituted. I replaced them all with small signal RF amp transistors.
