Live and let live. That is the fun part of the ham radio hobbyt, there is
something for everyone.

A question of unbalance who create a question of Usefullness. When the newbies
will be "experts" they will probably look for something
else? what the satellite community has to offer? Plans, future plans,
projection, funding campaign? Then they will also probably ask for
the "Usefullness" of LEO'S.
It's like eating peanuts before the lunch too much of it will only lead to a
loss of appetite!

P.S. AO-51 last V/S mode was at least a bit of challenge but with very few
users. It was a good time to test new S band antenna's. The
foliage absorption at those frequencies is also very noticeable i was able to
pin point every tree around my QTH making the satellite
usable only over 14 degrees reducing even more the usable time slot. The most
dramatic effect is the fades coming from the satellite spin
of the polarisation? i don't know but some are reporting receiving more fades
that usable signal. Is it mode S suitable for LEO.S i'm not
sure even if i was able to have a QSO with a mobile station in V/S!!!

WB6LLO, and other HEO lovers such as myself have nothing against FM LEO's,
and we are glad that there are hams that can get their jolly's over just
exchanging grids with each other or by popping off an APRS packet to let
everyone know that their house hasn't moved.
We wanted an echo and we thought we were going to get one, but the Echo
they gave us wasn't the echo we wanted. The echo we wanted was the echo
you get working through a HEO.
So, How many grids you up to?

The FM birds are all that I have access to at the moment. I personally
don't mind the fast paced callsign/grid exchange, but that doesn't seem
to float some people's boat. I do just fine. My income is very limited,
since being 14 years old doesn't really pay that much. I cannot afford
some of these fancy all mode rigs that can even make you a cup of
coffee. All I've got in my inventory is several FM UHF and VHF rigs that
get me on the FM birds.
Amateur Radio is a wide spectrum. There's lots of different things that
can take place in different ways. Some rely on the ionosphere to get
their contact, and other's rely on the pass predictions. It's not easy
to float everybody's boat, but most of the time we seem to get along OK.

First of all my thanks to RadioClub Telecomunicaciones Vigo for inviting
suggestions for an Amateur Radio payload for the Spanish cubesat.
Personally I'd be keen to see a 435/145 MHz linear transponder for Amateur
SSB/CW operation. Clearly the satellite power budget would present a major
constraint but perhaps a 30 kHz bandwidth linear transponder running about 100
milliwatts PEP output would be feasable ?
Maybe such a transponder could make use of the Software Defined Radio (SDR)
system already planned for the cubesat.
I wish you every success with whatever you decide to fly on the cubesat.
