[amsat-bb] AMSAT-Francophone launches a consultation, open to all, on the amateur satellite radio service. Feel free to participate! Publié le 3 février 2019 par Xtophe

[Scott Armstrong]

Every one of you has a perfectly good reason to build (or buy) an expensive
or inexpensive microwave stations right now, whether it is for the
satellite  or terrestrial radio services.

It's called, 10000's of MHz of unused and unexplored spectrum above 1 GHz.

The radio spectrum is a finite resource . However, nowdays it is being sold
off to the highest bidder which benefits a few companies so they can make
billions in annual revenue.

Basically use it or loose it.


There are not many satellites with microwave transponders now,  but in the
future?


Why wait for a satellite to be designed/launched?
Put something on the air for terrestrial use now. Explore and learn the
propagation quirks of the bands. Learn to appreciate what it takes to aim
an antenna that has less than 3 degrees beamwidth on a fixed target beyond
the line of sight.
When the time comes and a sat is put into service using
microwave/millimeterwave uplinks/downlinks you may be a head of the curve
and we may still have band(s) to use.
