Watch the video at https://youtu.be/cG4vHLs39iU.

For our April lecture, Richard Hinsley VK2ARH/W5ARH talked about the ADX (the Arduino Digital Transceiver) and the buildathon program he ran in 2023 for the Cowtown Amateur Radio Club in Forth Worth, Texas. His presentation includes a live demonstration of the transceiver.

Update, March 2025: Richard has updated the Constuction manual to v1.6 which incorporates learnings and additional information from our own MWRS event. Check out the Cowtown-ADX-Project repository on GitHub.
