I’m working on a test bed transceiver. I’ve wanted something that is modular enough, that I can swap in and out sections to test new designs (and just have fun). This is a Teensy 3.1 with a cheap Chinese DDS board that contains an AD8550. I am using one of my LM380 audio boards, a Sparkfun Serial two line LCD, and a few rotary encoders for tuning.
