I fear you are correct. About the likelihood of another HEO launch.
But I disagree about the rest.
The education card may gain us cheaper launches, but why are we
bothering? A recent post here mentioned a five-satellite CubeSat
launch, concluding that "Four of the CubeSats carry Amateur Radio
payloads..." Excuse me?
F-1 transmits on 145.980 MHz and 437.485 MHz which are both ham
frequencies. But hams can't use this bird, because unless you want to
look at earth images (and live in the vicinity of the ground-station) or
you are interested in the spacecraft's obscure telemetry, there is
nothing for you here. And if you ARE interested, you don't have to be a
ham radio operator to "use" the satellite. All you need is the
appropriate receiver and no license.
FITSAT-1 transmits on 437.250 MHz, 437.445 MHz and 5.840 GHz. Again,
all ham frequencies, and again, useable by ANYONE, with or without a ham
license, because all you need is a receiver (seeing as all you can do is
listen to some more obscure telemetry). The Hi-Brite LEDs writing CW in
the sky is really neet... but you won't see it unless you live near the
ground-station.... which I don't
WE-WISH (apparently) downlinks on ham frequency 437.505 MHz. It seems
to have a thermal imager on it, and presumably lots more obscure
telemetry. Once again, non-hams can use this as easily as hams because
it only requires you have a receiver, no interaction being possible.
TechEdSat will allow you (and any non-ham with a receiver) to listen to
the obscure telemetry (hereinafter "ObsTel") on ham frequency 437.465
MHz. Why you would want to, I can't imagine.
So. Is this the sort of "Amateur Radio Payload" that we should hope
for, if we continue to play the education card? Personally, I can't see
why we should bother. Judging by these satellites, the phrase "carries
an amateur radio payload" really means "usurps amateur radio frequencies
for non-amateur use for telemetry and telecommand on non-amateur
Let me make it plain. I have no objection to (and indeed, I support)
satellites being launched for educational reasons. I suppose that I
really don't even object to the HamSat frequencies being used for
non-ham purposes, seeing as WE aren't using those frequencies for
anything much. But what are we gaining from playing this education
card? The hope that occasionally, we can arrange the launch of some
short lifespan, low range, fast pass, single channel FM bird that I get
to shout callsign and gridsquare at for 6-8 minutes at a time, on a good
You know, I don't have 10M to spare, to pay for a HEO launch. If I did,
I would. I might scrape together 10K to donate. But honestly now, why
should I? Apparently there will never be another AO-13 for me (and
"real hams") to enjoy, because such a bird will offer little opportunity
But of course, I am nobody special, and not even an AMSAT member (I'll
tell you why, if you want me to) so you can safely ignore my post.
