Hi,
I think it takes about 2500m/s delta V to get from from LEO to a GTO.
How feasible is it to use some type of an electric thruster (high
specific impulse but low net thrust - eg a hall effect thruster or
similar device) to slowly crawl up to GTO from LEO?
I imagine that such a bird would

Hi Ross,

us to a LEO spot and develop like Ion engines or something so we can
eventually work our way to a high orbit, like with an ION engine, so it
takes a few years to get there because of the low push level, but hey a

For AMSAT-NA, I believe ITAR prohibits us from pursuing such opportunities.

In fact many, many VOLUNTEER hours have been put in by the AMSAT
leadership to get the two launch opportunities we have for Fox-1 and
RadFXSat. You wouldn't believe the work involved. They deserve a big
thank you for getting that done for us!
It would be wonderful to share everything going

Those guys originated as amateur rocketeers.

exploring opportunities for launches, even if you don't read

AMSAT-DL has Phase 3E mostly built, but the free launches of the past are gone.
I believe the area of 10 million Euros is what they have been quoted for a
purchased launch, which is out of the realm of amateur radio fundraising.

Or more likely a $10 million question which would be about the cost of a launch.

Peter,
Most of us really miss the old birds. I was transferring satellite QSOs from
the 1980s through the
early 2000s to my electronic logbook, and was amazed at what I worked.
AMSAT-DL has an excellent P3 satellite, currently being updated, but
essentially ready to go. Here is
the problem:
We need a very wealthy individual or two to get into the hobby and decide
they want to work a HEO! If I were to win the lottery or somehow come into
a few tens of millions of dollars, I'd pony up for the launch.
Honestly, though, the numbers aren't completely unrealistic. A long and

Well Paul,
If you think about it. We might still have a few thousand folks left that
are still members of one or more AMSATs. Maybe 10% or less are active at
all. For example, the last two passes (a few minutes ago) on SO-50 (2
active). FO-29 (2 active). So, the big question for me is why would
