rattlegram acoustic coupling

I'm excited about RibbitRadio.org and Rattlegram. This post will collect some notes about this ARRL Technical Innovation Award Winner (2023).

For the BARC TechNet on 11/18/2025 here are some links I'll be asking people to try out sending and receiving Rattlegrams. Hopefully I can just share the link to this post on HAM.live and then people can click on whatever they want to dive into. During the NET I hope people will take turns sending and receiving messages so we can experiment, learn, and have fun as a group.

  1. Free Rattlegram app for you iPhone
  2. Free Rattlegram app for your android phone
