Bill,
Nice job on the rotor.I also am building a similar lightweight?PTZ rotor.
It's very similar to yours. See my?video of?where?I'm at with it.?This is
part-1.?I should have?version-2?done soon.

Hi all,
I posted a little too soon about my rotator "blog" on Friday - I've
since cleaned up the post and added some high resolution pics (plus a
short video). If you'd like to take another boo here's the link again:
https://www.raspberrypi.org/forums/viewtopic.php?f=37&t=118737
It would be great to get some comments and thoughts (critical ones
welcome!) in the Pi forum.

When a message "appears on the BB" has a couple of different answers.
Your note "appeared" via the web interface a few seconds before 2:47 PM
EDT today
http://amsat.org/pipermail/amsat-bb/2015-August/054624.html
Google's mail server accepted the remailed message from amsat-bb to
wb3csy@xxxxx.xxx at 2:47:12 EDT. Once Gmail accepted the message, that
is the last I can see of it from the logs on our mail server. I don't
know when it "appeared" in your in your inbox. Google does strange and
mysterious things* to protect its users from spam, perhaps they are
using some new method that results in delivery delays that can't be
observed from the sending mail server.
Rick, thanks for this report. I'll see if there is anything I can do
to improve delivery from our end.

*Sometimes our mail server is "greylisted" by Google. Greylisting is a
spam control method where mail is temporarily rejected on the theory
that spammers usually don't attempt periodic retries to a temporary
delivery failure like legitimate mail senders do. It is not clear why
we are put on Google's greylist (or how we get off of it), but that does
not appear to be what happened here since they accepted the remailed
message right away.

She used to use a tripod and will probably use it again in the future. This
worked very well, but she wanted to try another way. I believe that kids
learn by making mistakes. Trying to hand hold the antenna and radios is a
mistake! She will learn.
The big issue with writing call signs for her is that she is still learning
to write. Remember, she is a very young kid. As her writing improves, she
will be able to do the paper method. All in time.
Thanks and 73,

Content-Type: text/plain; charset=utf-8; format=flowed
I'll throw in my .02 since the conversation has moved into a domain that
I have some experience with.
I've experimented with varying ways of holding antennae, holding radios,
holding hand mics, writing stuff down, and tuning two knobs for
doppler... As I, like most of my fellow humans, lacked the required 5
arms to hold everything, it was miserable. I tried a tripod only to be
unhappy with the reception, since I couldn't twist for polarity on the
fly. I got a voice recorder, but had the exact same thing happen as
ya'll did, although usually it was with cars, sirens, or low flying
airplanes blasting out the microphone. I was basically where she was
at... so let me, if I may be so bold, throw some pointers her way.
1. Get a headset and foot pedal. These things will run some cash, but
they're worth their weight in gold. Being able to hear the bird in your
headphones, blocking out the ambient noise is huge, and having the
microphone in front of your mouth all the time maximizes your modulation
of the transmitted signal. I got the Heil Micro Pro, and the FS-3 foot
pedal, but anything like these will work. Get whatever adapter is
required for whatever radio you're using to make them work. This will
solve several problems in one foul swoop, and free up a couple of the 5
hands required.
2. Find a fixed place to put your radio. I *think* Hope is still using
an HT, or a combination of HT's for her contacts. When I first started
on SO50 I was building cheap Yagi's for reception, and attaching my HT
right to the antennae itself with some zip ties. This had the dual
effect of minimizing my coax run, and freeing up yet another hand from
holding my radio. When I needed to shift for doppler, my free hand
reached to the radio on the beam, flicked a switch, and went right back
to it. Later on when I upgraded to the linear birds, and bigger radios,
I bought one of those little cheap folding tables at home depot for 20
bucks, and just carried it around in the Jeep with me. Having some place
to put the radios is big. With HT's, even something like a backpack that
has a strap across your chest is a great place to attach it, and keep it
close and accessible, without requiring another hand to hold.
3. Get tons of audio adapters. I like other people to be able to hear
what I'm doing.. I also want to hear things clearly... I also want to
record the pass without interference... these 3 wants typically exceed
the audio output of most radios. So, get a splitter, a recorder, a
volume attenuator, and an external speaker... or some combination of
everything. I will, at max, run a 3-way audio splitter, plug in my
headphones to one, plug in a speaker to another - with a long audio
cable away from me to eliminate any feedback, and a volume attenuator
feeding my voice recorder (because speaker output is typically too high
for most "line-in" plugs on voice recorders) into the third. It's a mess
of cables, but it accomplishes accuracy, demonstration, and recording,
all at the same time.
4. Write stuff down anyway. If I'm solo somewhere, no ones watching, and
I'm not trying to set DX distance records, I usually don't even mess
with my voice recorder. Even when I do, I've had it fail on me tons of
times. Usually it's cause I'm a bonehead and forget to check the
batteries first, but still the point is still valid. Practically before
every pass I work, I jot down who I am (yes, I stumble over my own call
sign sometimes...) where I'm at (especially useful if I'm somewhere
other than home) the bird I'm working, the date, and the AOS and LOS
times of the upcoming pass. That basically leaves me with callsign and
grid, as the only two important things I *have* to record after each
QSO. For bonus points, if I've got a sked with someone (the horror!)
I'll pre-jot their callsign and grid down, and usually write 'Q' or put
a check or something next to it when we've made the contact. Now, this
DOES require a hand to write, but you've got the notepad on that fixed
place you put your radio, so it should be a simple pen pick up, notate,
and set back down... right? :D
5. Ditch the tripod, hold the antenna. This one I know will draw fire
from some, but as an exclusively portable operator, I stand by it. The
nerves transmit a signal to the muscles in a normal human's arm
somewhere in the range of 200-220mph. This is a faster reaction time
than any rotor I'm aware of, and it allows you to make hundreds (or
thousands if you ever watch how twitchy I am) of corrections during a
single pass. Do it enough, and you'll completely forget you're even
moving the antenna, following its arc across the sky, and constantly
twisting it for the best signal. Your ears will hear how strong the bird
should be, and your arm will just react. I can't explain why or how, but
it just will. In the month or so I used a tripod, I never got the hang
of moving the Arrow, going back to transmitting, and remembering to move
it again. A few weeks of holding my arrow and letting my ears be my
guide, and it was like a 6th sense. And, as I mentioned to Sean KX9X
recently after his roadtrip, holding an arrow for multiple passes for a
couple straight weeks in a row, will make you a great arm wrestler.
6. Develop a system. This one kind of goes with the last two, but figure
out how you want it all to go together, and get comfortable with it.
Whether you're in the backyard, or on a mountain, set things up the same
way, every time, and be able to do everything by reaction, instead of
thinking about it. For example, I always setup so the bird I'm working
will apex directly to the left of where I'm standing. I always hold my
arrow in my left hand. My right hand does the radio manipulation, and
quick note jotting. My right foot is always on the pedal. I always have
my notepad immediately to the right of my radio. I have the radio at
exactly the height level, and high enough I don't have to bend over. I
color coded all my coax cables, I memorized where the step and channel
lock buttons are, and can find them by feel. Working a pass anymore is
just a reaction, I don't even really have to think about anything, I
just set my phone on compass mode, watch the clock, and go.
So this turned into a Novel, but I hope there's some good info she can
use. I am an exclusively portable satellite operator, and plan to be for
some time. I've ran into all these problems, and like to have think I've
solved them. I also plan to pick your brain in about 8 years on how to
teach my little girl, who (at 4 months old) really wants to figure out
where those voices in the speaker of my 857 are coming from, effective
ways to work the birds herself.

Hello all,
My wife and I will be taking 5 days to drive a rental truck from DFW, North
Texas to Boston to move daughter and new husband's stuff to their new home
and law school. The type of truck and the logistics of the trip will not
really work with casual satellite ops. Maybe someday.
However, I would love to make terrestrial QSOs with some of you folks along
the way as I will have a dual bander and a small antenna mounted to the
truck. Would love to say hi on local repeaters along the way.
Here is the route and rough projected time table.
Friday, August 28th, Afternoon-evening. Dallas, Texarkana, Little Rock.
Saturday, August 29th, Little Rock, Memphis, Nashville, Elizabethtown, KY,
Springfield KY.
Sunday, August 30th, Springfield, KY, Lexington, KY, Cincinnati, Columbus,
Cleveland.
Monday, August 31st, Erie, Buffalo, Rochester, Syracuse, Schenectady.
Tuesday, September 1st Albany Springfield, Boston.
There might be some schedule flex, especially the last two days but that
should be close. Contact me off list via my n5hyp@xxxxx.xxx email with
Callsign, city, repeater/s PL and other pertinent information.
Perhaps we can exchange more than just a Grid Square. What a concept.

I agree with the smart phone calendar idea. That's what I do, and the
heavens-above app has an export to calendar function that makes the

I guess because I have been living with it night and day since 2007 and
working on it over and over again for 8 years as PSAT. But you re right.
I don't like the ambiguity. Ill try to say PSAT(NO44).

Just curious...why do we not refer to this sat as NO-84? Seems to me that
consistency is the best way to go

PSAT seems to be returning to good health. We will keep the digipeater
off, but will now announce it is safe to resume PSK31 experiments.
Remember, when we ran out of power, great progress had been made with
Andy's pre-compensating PSK31 uplink software (below). Here also are the
latest elements for PSAT:
PSAT
1 90720U 15234.36512451 +.00008395 +00000-0 +21488-3 0 0099
2 90720 054.9897 293.1329 0244566 052.6872 309.6216 15.1526532401420
When PSAT-1 is using the PSAT-1 callsign, that means the digipeater is
off.
But as of now, PSK31 experimentation is authorized. 28.120 PSK31 uplink
and
435.350 FM downlink.

Subject: [amsat-bb] PSAT PSK31 experimental software
I put together an experimental program called DopplerPSK to compensate for
the Doppler shift on the NO-84 (or NO-83) PSK31 uplink. In essence, its a
PSK31 transmitter that is merged with an orbital propagator to cause your
transmitted signal to drift exactly opposite to uplink Doppler effect. It
does this in a phase-continuous correction so that you don't get errors
due to discontinuous frequency adjustments from controlling a radio in
discrete steps.
In the case of PSAT and BricSat, it should cause your signal to stay at
constant frequency in the satellite's uplink receiver, and thus you should
get a stable frequency on the FM downlink as well. In turn, this means
you should be able to use your favorite PSK31 demodulating software to
copy the downlink since the frequency drift should stay well within the
AFC tolerance of the software.
Anyway, if there are any adventurous people who are set up to give this a
go, I would be interested in seeing if it actually works.
You can find a rough quick-start guide (which contains an explanation of
how it works and what you need to get started) and the application package
on the rather minimalist page here:

It's an experiment, so be prepared for disappointment. I am :-) Andy

I receive a daily digest, but other than checking the archives, is there
any real-time or near-real-time way to
see new bb messages?

Rick mentioned:

*>* later, I still do not see it listed on the AMSAT BB.

OK, EMike rang a bell :-) The list won't duplicate messages. The settings
assumed you already received the message with your BCC. Try it without the
BCC on your next message and you should see your messages shortly afterward.
There is a Mailman setting for NODUP for all subscribers.
The timing of the message actually appearing for you also depends on local
settings. I use MS-Office Outlook for my primary e-mail. My Outlook settings
are to check for new mail every 300 seconds (5 minutes). So a message
actually arriving would be sometime in that 5 minute window depending on the
time in the receive window when I sent the message.
I use Gmail on my Android tablet and it usually receives messages sooner
mostly because it is not likely waiting for the 5 minute receive window as
in my Outlook settings.
