Ken,
Based on the specs you quoted above your email "can you use the ft-818 and
arrow"
The simple and honest answer is no, it would require different equipment
likely SDR based on microwave frequencies.

This one sure captures one's imagination, Frank!? That's a component missing

Is this a "self contained" project or do you anticipate that there will be

Wasn't there at one time like in the late 70's early 80's some Sat owner
(was on those giant big 12 foot dishes type of birds) that actually let
amateurs have radio shows on one channel every now and then?? I'm sure I
remember Ham shows on those birds Like Channel 22 vertical polarization etc.

I don't mean to suggest there's anything wrong with easy. I just think,
as a selling point, it's run it's course is all. How many times are you
going to watch a guy at a hamfest with an HT and a handheld? antenna
exchange grid squares? I would think sooner or later people just walk on
by.? "Seen it already, where's the new rigs?" It's the same ole, same
ole. I see an Arrow antenna sitting on a tripod, seemingly alive,
autonomously tracking a sat in Azimuth and Elevation while the operator
is busy making contacts, I'm going to stop because that's exciting! My
whole point in my post is to try and get AMSAT to do something,
anything, different. They need something new to excite the masses.
Judging by the response here, it won't happen. That's OK, not everyone
is going to see things the same way. I just know what I see and that's
an organization that is stuck in the mud and spinning it's wheels,
becoming more irrelevant by the day. I doubt my constructive criticism
will be received well. It never has been in the past. Another reason I'm
no longer a member. They don't seem to listen very well. I wish I had
the technical expertise to bring some of my ideas to fruition but I
don't. I can follow a circuit diagram and put together projects where
someone else has done the engineering but I can't engineer them myself.
I often wonder why someone hasn't come up with simple, relatively
inexpensive computer driven SDR XCVRS for satellite work. They seem a
natural progression from dongles like the Funcube but nothing like that
exist that I'm aware of. I'd lap up kits like that.
I believe Michelle is the YL I was speaking of earlier. She certainly
seems like a breath of fresh air. AMSAT needs more of her. People who
aren't satisfied to rest on past laurels and just maintain the status
quo. I'm about to go work some DX with my SDR that is based around an
Arduino and it's open source PowerSDR interface that is based on a
Raspberry Pi. Now that's exciting!

The concept of using the Internet for A/V uplink isn't really new.
Skype has been used by hams to deliver computer mike audio to remote HF
stations for years.
The concept was described as the Internet becoming an "extension of the
microphone cord."
Just so, Skype (or your A/V app of choice) could be used to deliver video to
to the sat service uplink station.
The Internet becoming "an extension of the video camera cord."
To take this idea a bit further, since there is no ham frequency RF involved
for the uplink at least, the sender might not even have to be a licensed ham.
Any school, college or club could immediately start building a ground
station from scratch or from COTS parts.
Even cheap Chinese satellite TV top boxes have been used for QO-100 DATV
reception.
This would certainly enlarge the client base for the use of such a GEO ham
system.
More money to pay the rent...

These are the Satellite APRS Packets provided in July 2019 per Callsign +
SSID. I am always curious about station setup: antenna, radio, TNC, iGate
software, altitude, location, etc. I have been considering reaching out to
each operator to gather specs.
This topic might make a neat article for AmSat, ARRL, or similar magazine.

Hi All,
I came upon this very interesting podcast about communications satellite
security since the 1980's.
It runs for about 19 minutes, is fairly recent, and is very informative.
Surely today, these communications satellites are more security protected
than what is described in the podcast ?
Let's all be careful with the design of such a ham radio system.
Security has to be integrated.
Listen to "Satcom crackdown. After the show."
