Thanks to everyone for their replies. There were many more replies than
there used to be which is a positive sign for the Mac community. I used
them for decades before switching in retirement but after looking at some
of the features that Don's software now supports, I might just convert back
to a Mac this fall/winter. My WIndows PC is probably getting a little long
in the tooth anyway. I was surprised to learn that there are a few
responses I received from the EME community, though most of them are
Windows folks.
TNX, 73 and stay safe!

You said you wanted this thread to stay positive so I will refrain from
making any comments about getting 35,000 hams to shell out $300.

By my estimation, they have already spent that amount on the newest
model BaoFeng radios .

I have set up a station before with a V dipole from the RTLSDR Kit with a
Raspberry pi 3B. I managed to capture images of Dorian last year. I can
point you in the right direction. Also captured on Windows and controlled
the dongle with Orbitron

Thank you for the positive thread.
Open Research Institute received news today about an additional $15,000
grant. This will help pay for work on GEO/HEO/Lunar payload transmit chain.
This brings the Phase 1 fundraising total to $65,000.
All of the work product is donated without charge to the general public.
This means primarily AMSAT and ARISS/AREx.
ORI has started on Phase 2 fundraising. The goal is $400,000 and will
finance multiple end-to-end engineering models.
Phase 3 is space-rated hardware.
Phase 4 is any costs related to any launch.
There is a path forward. Yes it's hard, but it's not impossible. Besides,
things worth doing are rarely easy!

Replying to myself.
It seems that the 2m amp is sure enough amplifying the signals heard
(including mine!). I can hear even ants walking around the satellite!!
I have been able to figure it out and tune properly for my signal clarity.
I will not touch those rascals.
Go SSB electronics!!!

Asunto: 2m / 70cm ssb electronics
I've been using the 70cm pre-amp for a little while and a few days ago added
a brand new 2m one. Both of them are installed on a small Glen Martin
tripod at roof top. GM holds the Leo pack which connects to Icom 9100.
Each ant has surge arrestors from Array Solutions
Could they live happy each other in that close range? I noticed something
strange with my hearing my voice yesterday that I've never experience
before. At some point, I sounded muddy but not to the other person.
It looks like I will have some good passes today. I will be able to hear
it again or not.

There are also some discussions (occasionally) on the QRZ and SatNOGS
forums. I think after people get them up and running, they lose interest
after a few hundred captures. I had an automated station that would
forward pictures to a web server and after a couple of weeks I decided I
had better things to do with that RPi.... I think that one turned into a
satnogs station.
But I still have WXtoIMG on my shack computer and will capture images
occasionally with my big antennas (I'm using Ubuntu 18.04).
Do you have any specific questions?

One thing that has not been discussed is regulatory restrictions.? Raising
the necessary funds to develop, build, and launch a satellite into MEO, HEO,
or GEO is not enough. One, if not the biggest hurdle to reaching beyond LEO
is the U.S. regulatory environment.? AMSAT VP of Engineering, Jerry Buxton,
N0JY, has brought this up several times on this forum and in his AMSAT
Engineering Updates, but, unfortunately, it seems to fall on deaf ears.?
Every time this conversation reemerges, it always comes back to money.
??
Space, as it turns out, is not that big, especially in relationship to the
part of it surrounding Earth.? ?The proliferation of spacecraft and space
debris orbiting our planet will soon be unmanageable.? Governments around
the World are enacting orbital debris mitigation regulations that are making
it harder to operate in space, and the U.S. is leading the charge.
? ?
THis is our greatest risk.? AMSAT Executive Vice President Paul Stoetzer,
N8HM, has been leading the AMSAT effort to address the pending regulatory
actions on orbital debris mitigation at the FCC. ?Look for a more
comprehensive update from Paul in the May/June edition of The AMSAT Journal.
? ?
Orbits above 600 kilometers are facing increased scrutiny, with required
flight-proven low-risk transfer orbit, long-term reentry, and/or improved
move-away-and-stay-away storage options for orbital lifespans more than 25
years. However, proving you can get there and operate responsibly is not
enough.? Every mission is closely evaluated to ensure it serves the greater
benefit of all, which, at this time, strongly favors commercial and
scientific interests.
? ?
Anyone who has been to space knows that there is way more to it than just
having a dream and a pocket full of money.? There are too many amateur
satellite projects left on the drawing board or wasting away in a storeroom
or garage, because those in charge did not take into account everything that
it takes to get there.? It takes a comprehensive understanding of our
regulatory challenges, a reputation built on flight-proven experience, and
established relationships with all key players in the space industry.? AMSAT
has that, and, more importantly they have a plan to get us there.?
? ?
The first step is GOLF-TEE, whose sole purpose is to demonstrate the
necessary equipment to operate above LEO.? GOLF is more than just a catchy
acronym for greater orbit larger footprint.? It is a commitment to return to
greater orbits.? It will not happen today, or even tomorrow, but it will
happen.
? ?
