[amsat-bb] ISS ping box (now PBBS)

[Edson W. R. Pereira]

What would be required (from the point of view of paper work, logistics,
approvals, etc.) to replace the current ISS packet radio TNC by a device
that would implement some more efficient digital communications? The device
could be a digipeater, but employing strong FEC and a more modern
modulation and framing structure and perhaps some better scheme for channel
access. Perhaps something similar to ngham.

With FEC and higher speed, we could accommodate many more users on a single
pass. A dedicated software application on the ground would implement the
modem and process information -- separating different types of messages in
different screens, providing a chat like mode for real-time communications,
automatically forwarding APRS packets, etc.

Am I day dreaming?
