Mailcast

Mailcast sends GB7RDG’s BBS bulletins on 40 m every hour in daylight, fountain coded so that a one-way link can work. A receiver listens through a sound card on your radio, or through a public web SDR, collects pieces until each bulletin is complete, and hands it to your own BBS. The idea of using a fountain code came from Perry M0PYL.
