First Look: Midnight Design Solutions Phaser Transceiver Anatomy of a Digital Mode Project
It all started innocently enough, really!
By way of introduction, I (K1SWL) am a die-hard home-brewer. Soon after becoming interested in FT8, I built a simple double-sideband (DSB) transceiver for the 80-meter band. It differed from the then-available crystal-controlled kits in its use of an Si5351 frequency source and Arduino-flavored ATMega328P controller. This was perhaps a bit of “overkill” for the application but with an eye toward frequency-agility down the road. It worked fine and I made a half-dozen contacts with it before setting it aside.
I had also completed a fairly involved homebrew project for the FT8 mode when I entertained the notion of a scheme of intermediate complexity. The available kit offerings featured a rock-bottom minimum parts count. As is
