I?ve enjoyed AO10 tremendously.
I have zero interest in a GEO satellite. I liked the challenge of an
elliptical orbit and the long chats I could have. The LEO satellites are a
bit boring. A two second exchange of grid squares yuck. I?d be happy to
contribute to a HEO satellite or a shared commercial amateur payload as a
life member of AMSAT I?m interested in it succeeding but I lose interest in
these LEO cube says quickly. I echo the concerns that AMSAT is not lobbying
Space X or Virgin for support.
Please stop saying if your TSgt interested join us.... why should I need to
your already in the leadership role responsible for just such activities.
Please help us I understand why this isn?t already happening????

We are 100% committed to returning to HEO. That is the goal of AMSAT GOLF.
Please donate at

As far as soliciting corporate support, conversations do occur, but have

We (AMSAT) has been in touch with SpaceX, as has AMSAT-DL. We launched a
satellite on their first dedicated rideshare mission. SpaceX is a business,
and they don?t launch anyone for free. We?ve tried, at multiple levels
including directly to Elon, multiple times.
We are also manifested on Virgin?s first operational mission, thanks to
NASA?s CLSI program. Virgin is a LEO only launch provider BTW.
Rest assured that this Officer and Director is beating the bushes for any
free or affordable ride available, but it is not as easy as perusing the
-bb would suggest. I will not however stand in front of a crowd again and
announce a project that is not much closer to a sure thing than in the past.
We?ve swung and missed too many times by promising things too soon. Remember
Eagle? Intelsat rideshare? P3E? P4B?
That being said, we?ve had multiple inquires in the past year for shared
missions beyond LEO, and are pursuing each to its end as we go along. It?s
difficult and frustrating work; a roller coaster of optimism and reality.
Meanwhile, engineering continues to chug along on Golf, with two launches
earned but not yet manifested, and is deserving of your time and/or monetary
support.

For the annual Appalachian GOlden Packet Event on 18 July (manning 15
mountains from Maine to Georgia), we have two holes in the 15 Hop packet

travel times)?
All you need is a kenwood APRS radio that will digipeat (and probably a
good bandpass filter).

Hello ATGP Folks:
>From a look at the latest 2020 ATGP spread sheet, linked on Bob's ATGP web
site, ( http://aprs.org/at-golden-packet.html ) two observations:
1. Greylock-11 has been removed and so is not man'ed !?!
2. Mt Washington-13 is not man'ed yet !?!
This apparently leaves Mt Equinox-12 isolated, without (from past

Mattias,
Thanks for having corrected the matter which may have created wrong
perceptions.
Thanks to AMSAT DL, QARS and the sponsors who made such a great Radio
Amateur bird possible, again congratulations for that.
That said I wish to confirm/comment your last paragraph, as follows:
In the Indian Ocean FR (mainly Reunion Island and 3B* Mauritius) we are only
a few Hams. With HF not going through these days the hobby was somehow left
on the side by some and QO-100 has really revived the activities.
To share my personal case I was able to experiment microwave (2.4/10GHz) and
modes such as ATV for the first time in my Ham life (licensed since 1977) as
there was no-one around to be able to contact on these bands and modes. Now
building a 3m dish experiment different types of feeds etc.. (some other
local guys also and even students).
In a nutshell a new world (or at least a half one) made available to us,
many experimentations and learnings. I feel like again being 16 (age when I
got my licence) as building antennas again, feeds, assembly of various
components to build the QO-100 station.
I just hope the ones not in coverage presently will get a in a Ham GEO
coverage soon and hopefully will fully understand what it means really.

"I would rather motivate the folks I vote for! They have far better
credentials than I!"
The only credential you need to work for AMSAT is a willingness to work your
ass off. The board members and other volunteers already have much more
motivation than the people who shout their suggestions from the sidelines but
don't want to roll up their sleeves and get to work.
"Commercial entities gaining recognition by providing in-kind services. Elon
Musk SpaceX, etc."
I get a weird sort of chuckle from the people who think the only reason we
haven't gotten a free launch from Space-X is because we haven't offered Elon a
free AMSAT tee shirt. It sort of reminds me of a six year old child who makes
an obvious suggestion and smiles as if he was the first person in the history
of the world to think of it. Elon already has about as much recognition as he
will ever need, and he is busy launching astronauts to the ISS and putting
30,000 satellites in orbit so everybody can access Facebook. (by my
calculation, with 58 satellites per launch it will only take 517 Falcon
launches to populate a 30,000 piece constellation). We need to come up with a
compelling answer to the rest of the world when they ask "why do you need to
use your ham radio when you could just use a cellphone or the internet to
communicate?"
