Absolutely! Other than setting the sat parameters for FalconSat-3 in the
GSC app (one time), the only WiSP program that I run during a pass is
MSPE. That handles all the send/receive of BBS files and directory
updates. For everything else, I use the same software that I normally run
for satellite activities (Orbitron, HDSDR, UZ7HO HS_Soundmodem, Direwolf,
etc.)

The very first thing to check is your computer's clock: it must be dead on
for successful doppler correction on the linear birds, whereas you may not
notice it much on the FM sats.

Several years ago, when the ISS repeater was still working, I was doing a
satellite demo for the scouts under the K9BSA callsign, working stations
right and left with 20 - 25 scouts gathered around the rig, when astronaut
Mike Fincke picked up the mic and said "hello to the scouts from the
International Space Station, NA1SS!"
I swear, the collective "thud" of the scouts' jaws hitting the floor could

Hi Greg,
Great idea! Good for that next step up.
The point of "who can hear it the loudest" is exactly that. It's subjective,
unmeasurable, and therefore doesn't make any one scout feel like they
weren't good enough. And for a beginner, or someone who can't hear callsigns
in SSB very well, it's a lot less stressful and difficult to say "look, I
can hear the voices" than "I've spotted KO6TH, K6CCC and M1ACB". Once
they're a bit more experienced, then you step it up a notch or two, but
right at the start, "I can hear it" or "I can't hear it" or somewhere in
between is more than enough to encourage that competitive spirit and get
them going!
73, and a firm left handshake,
John (XLX)

Subject: Re: [amsat-bb] doppler shift
Following the "contest" approach, perhaps set up teams of a couple of kids,
each with a radio and hand-held beam, and see who can copy the most number
of call signs. As preparation, you'd need to explain a whole lot of stuff -
what a bandpass is, what the track of the bird is through the sky, doppler
shift, etc, etc, etc. Then they can put it to practice.
A goal of loudest, or such, is kind of subjective; how would you really
measure it? Number of call signs, I think, would be simple and cause nearly
all of the challenges we face in operating to come into play, without being
so horrible that copying one call wouldn't be beyond reach. So everyone
would have some success and feeling of accomplishment, but still have a
competition and a winner.
Just a thought,
Greg KO6TH

Wow. Just wow! I bet they loved that.
Our experience was somewhat different, mostly because it was total luck. I'd
just finished talking to the two cub-scouts (8-10 years old) and their
leader who were sat with me, in one of the last sessions of the day before
they were due to leave. I'd done a bit of explanation about satellites, the
ISS, mentioned Tim Peake (we're British after all, and pretty much every kid
had heard of him) along with a little bit more about all that good stuff. I
glanced at my screen, as I didn't have any ARISS schedules to hand, and saw
that the ISS was about to come over the horizon, so I said to them "if you
want to try to listen and see if we hear anything, I'll show you how it
works". I set the expectation at zero, and they said "yeah, why not".
Tracking starts, and nothing heard initially, but then a dead FM carrier...
They didn't know what that was but heard a change in the sound. Then they
heard the ISS calling down to a ground station, but didn't understand the
callsigns. They did, however, understand the words "calling from the
International Space Station". Bearing in mind this was the first time I'd
heard the prelim calls (the ISS hadn't quite appeared over the Italian
horizon at that point I don't think), I was still working out what was going
on myself, but immediately shouted for the rest of the visitors who were on
site to join us. The two cub scouts sat by me still hadn't picked up their
jaws at this point - the thud was probably about as loud as your guys' jaws
hitting the deck too - but then everyone else piled in, and duly listened to
the entire contact, despite not one of them understanding a single word as
from that point on once contact had been made, it was all conducted in
Italian!
By the time the parents had come to collect their children an hour later or
so, video footage had been shared by one of the leaders into the Whatsapp
chat they run with their childrens' parents, and most parents had seen/heard
about it - they were talking about it on the way in to collect their
children, and the children themselves didn't stop talking about it - I'm
lead to believe it was the biggest surprise of the weekend, and the most
memorable moment for them!
For me, that ten minute pass was the highlight of the weekend, and if
nothing else, it made it all well and truly worth it, especially since I was
using two completely unknown and untested beams, a rotator kit I'd had in
pieces on my lap two weeks prior resoldering connections inside, rebuilding
motors and bearings for, and a radio I'd only owned for 3 months and had
barely played with. It was most definitely "a bit of a lash-up", but it
worked, we got the contacts we wanted (ie any at all), and the young people
throughout the weekend got a bit of a better idea about radio, AMSAT and so
on. We did keep a couple of 2M tape measure receivers handy too, so we could
demonstrate the simple end of the scale, but that made it even better.
You should have heard some of the guesses for the size of the automated
birds though - none of them ever imagined a cubesat can be as small as they
are...
73, and a firm left handshake,
John (XLX)

Hi Nick,
With AO-7 I would recommend practicing ahead.
Also on AO-7 low power is essential. As Paul mentioned, if the total power
consumption gets too high it flips into mode A.. Also know as: flipping the
bird. Some times there is an early warning when signals starts FM'ing,
other times no warning.
I would recommend running no more than 5W into an Arrow antenna.
