Learn about our work on the digital microwave broadband transponder for amateur radio. All work is donated to the general public as open source. This digital multiplexing transponder is a regenerative design, taking full advantage of a wide variety of cutting edge technology, intended for amateur radio use in space and terrestrial deployments. This review focuses on decisions made for the prototype board set that implements the transmitter side of the payload. Comment and critique welcome and encouraged.
