G3XBM pointed out silent key KL7R’s modification of a Heathkit HW-8 to do double sideband voice. It looks pretty straightforward, and would be an interesting modification. My own HW-8 isn’t exactly pristine, but I am torn between keeping it in its native state, and performing a modification to make it more versatile. Bookmarked for later.
Mark I think Mike and I started our Echolink conversations with a discussion of this project. I always thought that he needed to convert the HW8 final amp from Class C to Class AB. 73 Bill
