My thinking is this package could be designed as the (needed)
upgrade/replacement for the existing digi-peater/ham radio equipment
used in the "school contact" program. The advantage is a long-term
orbiting transponder with much easier maintenance access. As with
most of the advanced satellites being put up one would have a fully
functional spare. Since the environment would be much more friendly
so the unit could be built modular for additional ease in maintenance.
To aid in the "selling to NASA", I propose the telemetry system be
provided with data-ports for connection of school experiments in
support of STEM. Thus Amsat would be providing comm support in those programs.
A local mic, power on/off and channel selector would enable astronaut
use (both for ham and personal use).
So we hams would get part of what we want while providing support of
what NASA wants. Get creative on what this could do.
