Below is a picture of my latest project. After doing the transceiver thing, with a CE20A, mated to a SX-115, then the next transceiver project, a 10A mated to any Drake R4 series receiver, I had an idea.

John had checked in to the 20M Swan net with these very desirable "big Swans" until a few years ago. A big thanks to Eddie, NU5K, who handled John's estate and placed these on EBay. He packed them well, knowing they are indeed an important find. ... READ MORE

The tube-type Linear Master Oscillators (“LMO”) used in the Heathkit SB-Line equipment is a very stable and accurate means of controlling the frequency in the equipment. Unfortunately, as the units age, many LMOs develop a “warble” when tuning. This “warble” usually stops when the frequency control knob is not rotated. However, accurately “zero-beating&rdq...
