Toot

I think I posted an idea about what would essentially be a voicemail box for ham radio. Not a repeater, just a place to drop traffic. This is how we treat some digital modes (packet BBS), but could be simplified. (For a complex version see https://mastodon.radio/@W1CDN/111749840174214707).

It might be useful for getting health and welfare info out of areas when bandwidth is a problem. 1/2

So your station would sit on the air at a known frequency and listen for traffic. Could be voice, could be CW, could be digital (although with digital you might have more capabilities, so why use this). Station could beacon to prove propagation. A person without other methods could use a portable rig to send an "I'm OK" message to the receiver. The receiver would be automated on the backend to queue up traffic for a human to process--and that human would not need to be a licensed amateur. 2/2

This is, of course, a thought exercise that I'm sure would need refinement. I am not an expert, nor should you trust me rather than people who actually manage communications for a living. 3/2

@W1CDN One of the ideas of the RFBitBanger radio is to be an easily stashed cheap radio with which alphanumeric messages can be sent via QRP. It uses a protocol called SCAMP which is designed for slow but highly reliable communication
