Sadly Satnogs isn't suitable for the job being it's for telemetry only,
also I don't believe it forwards telemetry to AMSAT-NA or AMSAT-UK so radio
amateurs would be better off with a different solution.
Sadly ICOMs remote software isn't that great for satellite work, I'd also
love to see a better remote solution even if it's just for working passes
in a different room in the house.

Joseph,
You need to consider what the alternatives are. In the case of the United
States Government, being able to make their own flavor, even if they have
to hire a contractor to do it, is tremendously reassuring. If someone has
bad intentions in the Open Source world, or writes pernicious code, people
*see* it. My experience in being an officer of a Fortune 100 proprietary
software company, and having many proprietary software companies as
customers, is that disgruntled employees and their deliberate or accidental
code issues are part of every proprietary software product, and remain
secret. I have been paid big bucks to clean this stuff up during one
company's IPO. What was there would have sunk them if ever discovered.
Government proprietary software customers have to work hard just to get the
right to examine proprietary software, maybe in a controlled room with
severe constraints on their action. A really big concern for the United
States Government right now is that the ICs that they buy actually perform
as specified and do not contain deliberate surprises. The reality for them
is that 100% disclosure and tracing of processes is essential. Open Source
provides a good way to do it. All of the other alternatives provide a
significantly larger administrative load.
Thanks
Bruce

I like watermelons. The board even has stated that the legal funds DID NOT
come from memberships dues.

In most (or actually, all) non-profit organizations I have been involved
with, unless money is expressly donated for a particular program or
purpose, everything goes into a general fund.
Was there a donor who gave money for the specific purpose of looking for a
legal way to get rid or punish a member? Or to stonewall information
requests from duly elected directors?
Yes, the connection of legal expenses to membership dues is valid and, let
me tell you, concerning.

Hello from Don KA9QJG Ham for over 40 yrs. Hope Everyone is staying Safe
and Healthy.. I hope its ok to change the ongoing thread.. I have heard
some New Hams using the Oscar sub bands for FM Simplex. Below Is the ARRL
Band Chart Now Reads New
144.30-144.50
New OSCAR subband
145.80-146.00
OSCAR subband
They are using Freq 144.315 FM Simplex. One was telling a story over 25 yrs
ago they were using this Freq and a complaint was made to the FCC He got a
Letter from the FCC . And He called respond the complaint and told the FCC
that this was the Old Oscar Sub band that had not been used since the
sixties Sats were Not up and working anymore. And the FCC Said do not
worry about the complaint. So after listening to all this on 144.315 over
a long time I thought the best place to get a real answer would be here.
Thanks everyone Please Stay Safe and Healthy

You can download every bit of telemetry AND the un-demodulated audio. If
AMSAT isn't getting it, they aren't trying.
Most of the ground stations are identified in the SatNOGS system by their
Amateur callsigns. Look at https://network.satnogs.org/stations/
This is definitely the largest Amateur ground-station network. And since it
is Open Source, if it does not do something you wish to do, you can
extend it.

It all goes in the same bank account. It might be that Yasme Foundation,
the ARRL Foundation, or ARDC inadvertently gave the money for this. They
would be upset if they did. In which case that might provide one reason
that their latest grants are to ORI.
So, we might say it's some hundreds of memberships, or 1/2 Yasme grant or 8
ARRL Foundation grants, or 150 President's Circle Basic contributions or a
piece of our US Government forgivable loan.
But it's all the same money, in the same bank account. We can't really wave
hands about whether it is memberships, donations, or grants, or the
loan to *paper
over the impact of this money being spent unwisely.*

While I get your pro-open source, and I've plenty code-shared that is,
my point was really that its not suited for what dave wants todo out
the box, unless he wanted to build in bidirectional audio streaming
and other functions that would be needed for using it on linear and FM
transponders.
I totally get its open source and a large network, I do have some
personal concerns regarding the system, but that really isn't the
topic of this email thread.
