Texas star dx 500 cw to amp conversion

I was bored earlier and flipped, cleaned up and resized that pcb layout ready for printing on acetate for dry film etching.

edit: But now that I look at it, I think it should be changed a little to get that capacitor on the board. There is no reason a trace cannot go up under the resistors and a bit added to the top of the board to hold that capacitor.
edit2: done

It was a few years ago and all of the ones I see now no longer have the board.

Local tech friend of mine said they did not have the board. It's been at least two years ago, and I can't remember what he said about enabling 11 meter. I faintly remember it was just moving a capacitor.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
