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.

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!

Hi Michael,

I don't see anything wrong with "easy".? Easy gets people to try new
things.? I never dreamed I would get into satellites until I read I
could hear them with my HT and rubber duck.? If not for that I
probably wouldn't have followed up and got on FM satellites with a D72
and then linear satellites with a pair of FT-817s.

My circumstances demanded that I operate portable, swinging an Arrow
antenna around.

Only now, a few years later, am I at the stage where I'm thinking
"yeah, it would be cool to do this and that with an Arduino".?
Luckily, I'm retired and now have the time to (slowly) learn how to
program one.

My point is if people see that some new aspect of amateur radio is
actually easy to get into they're more likely to give it a try.? Then
they'll see the opportunities to use neat tech to make the experience better.? That's how I see things happening.

??Expanding on my previous thoughts pasted at bottom...

It seems to me that the 'easy" thing has run it's course. Again, just
one mans opinion but I think if you had some sort of setup outside a
hamfest with a card table and a folding chair, a sat rig and an
Arduino
based rotator controller running off a laptop or I-pad and
antennas on a
"WRAPS" ( I think?) type tripod tracking both Azimuth and Elevation,
you'd attract the more technically savvy hams. Probably more youth
too.
I know in my model railroading hobby that the fact we can now run
trains
with a smart phone is a big draw. Back in the day, on the not so
great
passes, I would sometimes fire up the shack computer and my BASIC
STAMP
based Sabretrack homebrew rotor controller and walk outside and
watch my
old surplus OR-360 TV rotators moving my homebrew antennas to
track the
sat across the sky. To me there was a certain "coolness factor" in
that
which can't be matched by the guy holding the antenna in his hand and
waving it about. In fact, my whole idea in buying the beat up
telescope
tripod was to sit outside at a table with a couple of HT's and my old
notebook computer driving? the thing with a couple of light weight
antennas on board. Yes, I know that I don't necessarily need to track
elevation with an LEO but watching the antennas track both is
awesome to
me. I think we miss the boat sometimes by constantly harping on and
touting the "easy" aspect of it. Sometimes complex and high tech
is more
attractive. Digital modes, SDR and computers have made HF radio hi
tech
and cool again, at least for me, yet the sat hobby seems to be
bending
over backwards to over simplify and make things BORRRING! Even model
railroads are computer controlled these days! It doesn't have to be
super expensive either. An Arduino and some DC motors and gears
can be
had for less than the cost of a meal for four at Mickey D's. All my
OR-360's were was Mabuchi style hobby motors hooked to a gear
train. You
controlled direction by switching polarity of 12VDC sent up the
line and
they had position pot feedback. EasyComm format for AZ/EL. But
hey, what
do I know, I've only been in this hobby forty one years. Just my
opinion
anyway. That and five bucks will get you a "Venti" designer coffee at
Starbucks.

Michael, W4HIJ

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.

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...

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.

Is this something I can do with a pair of FT-818s and my Arrow antenna?

I got a call from a space industry contact who saw this post.

DVB-S2X down, FDMA up, single carrier, reasonable rent, public safety partner. Money for a year's worth could be raised in a single campaign.

I'll see what I can find out and draw up a proposal.

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.

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.

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.
