I've been working sats off and on for many years. I must admit that I
haven't done much since RS-12/13 and RS-15 went silent. I believe that if
we had more "easy sats" with Mode VHF up and HF down they might be more
popular. Tuning and alignment weren't as critical.
Just my two cents or so.

Like many hams (I suspect), I dreamed of working satellites for decades.
Followed them with at least a passing interest but always seemed to put them
off till "someday". Even during the craze of the "work satellites with your
handheld", I was distracted by other priorities. When I got involved in
VHF/UHF a few years ago, and purchased an Icom IC-910H, I kept thinking I'd
finally pull the trigger. But years passed without anything other than
weak-signal contacts being made on that rig.
A few months ago, I finally decided to give it a try. Downloaded SATPC32,
and updated my keps. FO-29 was the next satellite coming my way, so when I
was inside the footprint, I tuned around a bit, and found some stations
coming in. Cool! I was actually hearing hams on satellite---next up was
answering a CQ...nervously I pushed the PTT on the mic.
82 grids and a few hundred contacts later, I'm having a ball!
I don't miss the birds that came before, but just enjoy what we have now. My
only complaint might be that more folks are not active on F0-29 and VO-52.
Even SO-50 can be nearly empty after midnight.
My understanding is that within the next year we'll have 2 or 3 more linear
LEO satellites, and possibly another FM bird, right? While we may not work a
lot of DX on those, we should get to the point where no one has to wait long
for "something" to be overhead. That's exciting to me!
AMSAT is staffed with wonderful volunteers, and seems to be doing great
work. I'm thrilled to be a member, even if it is #38965.
The good ole days are now. Get on the birds and make some contacts. I need
your grid! (ha, ha)

I did the same... I worked the the FM sats. I started with a IC 821
until it crapped out on me. I was on AO40 and it worked well until the
radio went south.
I got a IC910H and I already had SatPC32 so the two worked very well
together.
I have a second IC910H that I use for terrestrial comms. I have a 23cm
module
in the first one.
I have been having a great time working FO29, VO52, AO7 and SO50.
SatPC32 does great in controlling the radio and rotor.

I think everyone on this list should play Kerbal Space Program (
https://kerbalspaceprogram.com/) and you'll realize the getting into
sub-orbital flight is easy, orbit however is not... It's actually realistic
enough to learn orbital mechanics but fun enough to enjoy as a game... It's
the un-official pastime of many young rocket scientists... hehe.
getting to orbit is hard and requires most fuel. Also, for the Virgin
Galactic and any plane/balloon based launch you are looking at ~500Kg
payload (at least that's whats stated on Virgin Galactic's website for
under $10 million)... sounds great until you realize your still spending
several million dollars where as a commercial rocket (lets say SpaceX
Falcon 9) is ~60 million for 13,500 Kg... There are many universities and
NASA departments making cubesats but the small satellite market is nothing
compared to the large payload (or many small payloads) to orbit market, and
that's where you'll find business going... Sorry guys, no ones building a
launch system for us...
Also, if AMSAT was to create a balloon or plane launch system those are
incredibly complex launch platforms that have to work in order to even
think about the satellite working... It's hard enough getting volunteers
for the satellites nevertheless a launch system. The launch providers are
in the big payload businesses and that's the market we're stuck with.
On another note, every round of comments comes back to: "lets have a long
life satellite...", "Let's put engines on the satellite", etc... Well fact
is we need to develop that technology in LEO before even trying to get to
HEO ourselves. That's a technological feat in itself. It seems to me that
some people haven't quite grasped the fact that AMSAT *is developing a
standardize platform of technology to bring to longer life and new
technology to CubeSats and HEO* and that platform is called... FOX...
Supporting AMSAT Fox is supporting AMSAT's potential future in HEO.
Also, don't quit, volunteer.

Well said, Les!
I've been having a blast ever since getting my minimal satellite station
put together, even though I'm in a really terrible situation for it (urban
environment surrounded by buildings, high noise, 152 MHz pager transmitters
a quarter mile away, and a military spread spectrum radiolocation system
crackling all over 70cm).
I'm using a Yaesu FT-817ND for the uplink, an Icom IC-R10 for the downlink,
and an Arrow antenna. I had to add a PAR Electronics 152 MHz notch filter
to keep the pager transmitters from overloading my receiver, the AMSAT
Broadband Preamp to compensate for the relative deafness of the IC-R10 (at
least on 435 MHz), and an MFJ duplexer to cure desense when operating Mode
J. I carry the radios in a small tablet bag around my neck, go outside into
the parking lot/courtyard of my building, and work the passes. It's a lot
of fun. I finally got everything going just under a month ago and have made
56 QSOs, including some DX like CO6CBF, YV6BFE, and PV8DX. Almost worked
EI3GRB and EA8HB (both of whom heard me, but just couldn't complete the
QSOs). Even made a Mode A QSO on AO-7 with AC0RA using an AlexLoop Walkham
Portable Magnetic Loop to receive the 10m downlink.
Sure a HEO would be great (I've checked the pass predictions for AO-10 and
AO-40 and my south facing balcony would work wonderfully) and I look
forward to the challenge of assembling a HEO station when the day finally
comes that we are able to get a launch. I think a great compromise would be
a bird in a similar orbit of the old RS birds (30 min passes and being able
to work deep into Europe and out to Hawaii on a regular basis would be
great), but as Frank, K4FEG, likes to say, I'll work whatever's up there
until the antennas burn off during reentry.
See everyone on the 0101Z pass of FO-29!

Contrarily... I believe if we had more "hard" sats that would present more
of a challenge to many. If it were easy, everyone would be doing it. The
difficult we do immediately, the impossible takes a little longer!

Amen, I second that motion...
Third word hams who do not have 70cm rigs can work the sats more easily
(70cm FM gear is very rare here, not to mention SSB)
The 2m uplink is workable with transverters and HF multimode CAT capable
rigs are almost ubiquitous for the 10m downlink

I never buy lottery tickets. However today at the grocery store I saw the
powerball up to $400M. I bought a couple thinking HEO.

Take a look at this:

ons/1411
Does that mean that financing an HEO bird through lottery winnings is
impulsive, hi?

The Cygnus launch only goes to LEO, I thought you wanted a higher orbit for
P3E. The Cubesats that were deployed on the test launch only stayed up for a
week before reentering.
Also, integrating a large and complex satellite with a propulsion system is
probably adding too many complications to a program that is under immense
pressure not to screw up the first launch. Inert aluminum proof mass cylinders
are much easier to integrate into the launch vehicle.

You don't need Kickstarter, just call Martha or donate online. AMSAT was doing
crowd sourcing decades before it became cool.
Also, would you guys PLEASE LEARN TO TRIM YOUR EMAIL when you hit "reply",
there is no need to quote and rebroadcast the entire days amsat-bb digest when
you want to reply to a message.

Subject: [amsat-bb] SO-50, IC-910H, and Sat PC32 Issues
Message-ID: <523B3315.9090602@xxxxxxxxxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Before I ask again for assistance, I'd like to say that I've read the
"manual" for both the software and the rig, experimented, and tested on
my own trying to resolve these issues. This includes staying up well
past midnight so that I can run tests on the bird without bothering
other users too much.
Here, briefly is a description of my station, and the issues I'm
experiencing. Any assistance or advice in resolving the problem would be
gratefully accepted:
Running an Icom IC-910H into antennas in the attic. The 432 antenna is
an Arrow 7 element Yagi, mounted at a fixed elevation of 25 degrees. The
2 Meter antenna is a 6 element K1FO Yagi, mounted horizontal. Both can
be rotated on the stack in azimuth only. Feedline is 75' foot runs of
1/2" hardline with antennas mounted in the attic.
The 432 antenna has an ARR mast mount pre-amp, while the 2 Meter antenna
has an SSB Electronics mast mount pre-amp. Performance on FO-29, VO-52
is fair to good. High elevation passes on all satellites seem to give me
reception problems, but down nearer the horizon things are good. Hoping
to upgrade to AZ/EL in the near future.
I've learned how to deal with Doppler on the other birds, and generally
can used the stored corrections in SATPC32, or adjust it on the fly
using the software to hear my own downlink well, and work other stations.
SO-50 ISSUES
======================================================
However, on FM I continue to struggle.
A.) Reception is poor. Especially high elevation passes.
B.) Successful reception of other stations requires adjusting the RIT
control on the rig. Often to "plus" 5 KHz and sometimes to somewhere in
between 0 and +5 Khz.
C.) Switching the rig to FM Narrow mode helped, but did not resolve the
problem.
D.) Attempting to adjust for Doppler using the software control doesn't
seem to help much.
E.) I can only rarely hear my own downlink on this satellite, even in
the middle of the night when the bird is empty.
F.) Numerous reports of others calling me without success, even though
I'm getting into the bird fine.
I realize that polarity is an issue with all satellites. Signals arrive
out of phase, and I have no way to compensate. Also having a fixed
elevation is a problem, and explains the poor performance at high
elevation. But I fail to understand why the system seems to work well on
other birds, but not SO-50. What am I missing?
