Inspired by Heathkit, author aimed to enhance his Yaesu FT-817 with audio and RF processing. Design goals included a compact enclosure, PCB simplicity, matching jacks, a visual meter, and a built-in signal generator. Despite challenges in finding a suitable compressor IC for a 5V DC mic jack, he chose the Analog Devices SSM2165/2166 series. Prototyping with a solderless breadboard, author planned a PCB layout for its versatile performance in communication use.

A website deticated to Boathancors, with lots of pictures of some of the most popular ol tube radios from Hallicrafters, Hammarlund, Heathkit, Lafayette, National, Zenith and some projects. Boatanchor is amateur radio slang for heavy old tube radio equipment. Originally derogatory, the term is now used affectionately. Seeing an old set working like new after careful repair, cleaning, and alignment gives one great satisfaction.
