You are confusing a bandplan with an allocation. You may want to check
http://www.itu.int/en/ITU-R/space/AmateurDoc/ARS-ART5_E.pdf for the actual
allocations.

Sorry,
But on hf only allocations for satellite ops are existing within 29.300
- 29.510 kHz for IARU Region 2:
http://www.iaru-r2.org/documents/explorer/files/Plan%20de%20bandas%20%7C%20B
and-plan/R2%20Band%20Plan%202013.pdf
Same as in Region 1 and 3:

Bandplans were modified from time to time ;-)
So please contact your IARU HF Manager for further information.

People get sloppy sometimes. That should have said "US FCC
regulations allow space stations over the entire 10m band"
(specifically, 47 CFR 97.207(c)(1)).

If you have an HF radio...

These days, a lot of hams don't have HF capability, and many have no
desire to add that capability.

Just like some have no desire for VHF or higher. A major majority of hams
have no gig or higher. If we limit ourselves to what we assume others want
we limit progress and learning and stuff, that's not good.

I find that RS12/13 had 8 watt transponders. WOW! That's for 40 kHz
bandwidth.
Or if one user was in the passband, then he got all 8 watts!? That coiuld
be a very loud signal? What was Mode A and KT downlinks like? Were they
armchair copy or pull them out of the noise contacts?
To get down to say the 2 watt level for a cubesat, then this suggests only
a 10 kHz wide transponder. And with 3 kHz signals, that could only be 3
signals. AND, what is it like near the edges of a super narrow filter?
Does the steep phase changes on the edge of the filter then distort SSB?

That's True. I forgot that 99% new hams no longer come into the hobby
via the HF bands.
Back in the old days it was the other way around he he he. Everyone or

All,
Bob specifically asked about a HF to HF transponder, presumably because the
opportunity was limited to such an animal. Let's keep that in mind.

It was extremely strong. I often worked it listening with a magmount
antenna. 2w and 20khz would work fine.

Some are convinced that "real ham radio" ended with Novice
Enhancement, or removal of code from the Technician license in '91 or
the withdrawal of Elements 1B and 1C in 2000 or ... or ... Whatever.
I know the test sessions I lead are busy as was the Tech/General class
our club ran this past spring and I also know that some of the newbies
aren't often heard On The Ultra Highs because they are too busy on HF
(listen for some of them on our local 10m net, Wednesdays at 2000 CT,
on 28445 kHz).
Getting above 1 GHz isn't easy. Actually, 900 isn't that easy,
either. In fact, I'm looking for a clean IC910H with the L-band
module so I can do just as you suggest. :-)

I would add that I too got my start with the Russian RS satellites and
would cast my preference for 15 and 10 meters as there is plenty of band
width even if propagation on HF improves. I had good fun working the RS
satellites with mnimal antennas and other equipment. I have no doubt that
if we had a new bird on the HF bands it would be very active and get a lot
of new comers hooked.
