Indeed sir.
If we can get ahold of Kevin Bacon maybe we can get a GEO sat!

Actually, from my perspective right now the top barrier is orbital

the kicker right now is that they have to be proven and approved by the
FCC. In that we know of no such device(s) available at this time,
keeping within the current expectations of 3U. A change in size

Another option is to find a launch with a low enough perigee to
naturally decay in 25 years, but whether earning an ELaNa launch or
buying one, we will always be secondary payload and don't have a
issay in specific orbit parameters.
One more option is rideshare, and that is also in active discussion. >> > > The point there would be that the onus of orbital debris compliance
someon the satellite we hitch a ride with, although that also goes into not
having a lot of say on the final orbit not to mention satisfying a
primary payload that everything will be just fine if they take us
along. And then again, there's likely cost there too... We have
youoptions that wouldn't necessarily require lots of money, they just won't
be happening today.
Other possibilities? As far as I know we are pursuing the current
options available per NASA and FCC, but that doesn't mean that there >> > > aren't other possibilities. If you have any, keep in mind that building
a good case for use of whatever the possibility might be is key to
gaining any approval. And 90% probability that whatever will get
goingback in less than 25 years is a tough challenge.
We are bucking a trend, general CubeSat missions are happy with
islower or from ISS, and bucking the trend not new with AMSAT but it
well asnew in this world today because of the regulation and stakes as
ofthe fact that most everyone we deal with has no knowledge of AMSAT
beyond the record the we have created and grown in the last 4 years
availablelaunches. We are not magically known just because we launched some
pretty cool satellites in the past. Hopefully we will be known by more
through our continued contact, cooperation, and "by the book" production
and delivery of CubeSats with NASA, FCC, launch integrators, and others
who we look to for these launch opportunities.
Or get a bunch of money because that probably is the second biggest
barrier...

This is interesting for sure, Michelle.
Traditionally, amateur satellites (and symbiants) have been self-contained
RX and TX systems.
Conjecture follows...If DVB-S2 could be negotiated to provide the
downlink, the missing component is an uplink within the amateur bands (just restating you).
That means (if it can be negotiated), our work is cut in half because we
are reduced to providing the uplink (RX) side and a pathway to the DVB-S2 downlink. Of course, this is an oversimplification because we would also need all of the things that make a symbiant palatable to the host system. Interesting thought experiment, though.

Since the potential rentable birds generally all use DVB-S2 as a downlink, then the work Phase 4 Ground is doing to bring that entire standard to open source amateur radio use would seem to be quite relevant.
Different question is how to handle amateur uplinks, but there are some internet backhaul options there that would work very well as an
intermediate step.
Great question and discussion.

Just from the outside looking in...
AMSAT APPEARS only to be interested in hoisting flying repeaters and PACSAT/APRS and showing the average ham how "easy" it is to work sats
with a handheld and a simple antenna. I guess that's all well and good
but I didn't get in the sat end of the hobby for "easy". I wanted a new challenge. I was too late for A0-40 because of lack of funds for a
station but I did have fun for awhile chasing AO-51, FO-29, AO-7 etc.
with a TS-2000X and a homebrew rotator and antenna system.
Unfortunately, life got in the way and I needed family funds so the
Kenwood hit Ebay and I'm inactive on the birds now. I sometimes consider buying a couple of Baofengs (you should ALWAYS operate full duplex but
that's another thread) and getting back in on the cheap, I even recently bought a beat up old telescope with a computer tracking tripod system I spotted at Goodwill, but honestly, the challenge isn't there to give me motivation.
Before everyone flames me, as I said, this is from the outside looking
in and just one man's opinion. I really wish AMSAT would do something, anything, to change my perception. Seems to me I saw something about a
YL running for the board who's interested in open sourcing stuff. Her candidate statement was IMHO, a much needed breath of fresh air but I'm
no longer a member and don't keep up so no idea if she got elected. If
AMSAT wants my membership and donation dollars back, they need to change perception and I suspect there are many out here in the community who
feel the way I do.

Just curious. It seems as though it is getting difficult about placing he
ham SATS dueto cost. I wonder what may happen if the cost is so prohibitive that AMSAT could
possibly go by the way side. Just asking.
