I can't understand this kind of attitude.
First of all, let's talk about why cubesats are important. Cubesats
are inexpensive enough for them to be launched with some regularity
using funding sources that are available to universities on small
grants. They have launch opportunities which are affordable and
relatively easy to find and schedule. That means that people are
building satellites and launching satellites with some regularity.
The recent PSLV launch put nine different satellites into orbit.
These satellites include one which contains a Mode U/V transponder,
cameras, digitalkers, slow scan tv, and almost all have CW beacons.
That's pretty darned cool. Monitoring their telemetry has been a fun
activity for me, and I look forward to using the Delfi C3 transponder
when its available for our use.
And yet, we have radio amateurs complaining about them. About them
using _our_ frequencies. Using _our_ equipment to receive
telemetry. We sound like a bunch of spoiled brats. We should be
trying hard to encourage cooperation between these university projects
and amateur radio, not by _dictating_ what they do (after all, they
aren't going to get grants to satsify your own personal desires) but
by trying to find common ground between their goals and our own. But
we have to remember that we _aren't paying for their launches_ and we
_aren't doing their research_. We cannot dictate what they do.
With luck and careful planning, we can _participate_ in what they do.
If we say "if you are going to use our frequencies, we expect you to
give money to us", the only thing that will happen is that they will
cease to use amateur frequencies.
The opinion of a large number of hams on this list seems to be that if
we aren't launching P3-E or Eagle into HEO, then the amateur satellite
is doomed. I think likely should be filed under "self-fufilling
prophecy". Yes, we'd all like have big hardware in HEO. But how
many of those launches have we had in the last decade? What are our
future prospects? It seems to me that we should be paying much closer
attention to these cubesat launches and trying to understand how they
represent an opportunity for amateur radio.
But even if you don't buy that argument, try this one: these satellite
launches have nothing to do with our own inability to get satellites
into orbit. They aren't filling slots on launch vehicles that we
desire. They aren't crowding frequencies that we use. They aren't
pulling money from any funding sources that amateurs use. So if you
can't get behind them, how about just shutting up about them. If they
aren't of any interest to you, so be it. But stop complaining about
