I have prepared my 2-m yagis. Now ready to set them up to use on the birds.
I'm thinking setting one horizontally and the other vertically, spaced
about 1 ft apart on a boom. Now, how to measure the coax and connect them
for circular polarization?
FYI, when all set up, I'll put the project details on my Dropbox with a link.
Request ideas, guidance, advice, comments, please.

YES! very fun project. I caught the same pass Paul is referring to, we
only got 7 frames :-( here at VT. The fun (and proud) part for me was
it was all part of a undergraduate class project for the satellite
communications course where the students had to simulate the orbits
(using STK), predict pass windows where the crosslink was possible (line
of sight from AO73 to FO-29 and LOS from FO-29 to VTGS), then for each
pass window do a link budget computation for each 1 second timestep of
the established chain event, and do a doppler curve estimation.
The proud part was that two of my students (undergrads) were dead on
with their predictions, and were present during the decoding event and
therefore got a half letter grade bump on their project grade since we
successfully demodulated packets based on their simulations and
predictions (not only did they pick a good window with a higher chance
of success, their doppler curve matched nearly perfectly, allowing us to
tune correctly to decode the packets).
The magic part that folks should keep an eye out for is trying to make
the attempt when AO-73 is in sunlight since you get a 10 dB bump in
output power from AO-73 in the beacon. That was also a great teaching
moment during the attempt where we could see the signal drifting (up in
frequency since AO73 and FO29 were closing on each other, not down like
you might expect with normal doppler) in the spectrum display, but
barely breaking the noise floor, then all of a sudden there is this 10
dB jump in SNR (AO-73 coming out of shadow and into sunlight) and
packets start decoding!
very fun project, very hands on for the students. Do some research,
develop a simulation, synthesize something meaningful about the real
world from the simulation, try it in the real world, and then explain
what worked and what didn't and why, but with actual satellites in orbit!
Also, they used the free version of STK in the class project and then
wrote scripts in python to process CSV data generated by STK, so all of
this is simulation stuff is doable by hams with completely free software
and tools.
One of my all time favorite student projects......brought to you by the
fabulous folks at AMSAT, in this case our japanese (FO29) and english
(AO73) brethren!

I presume that you know that to get circular polarization, one set of
elements needs to be electrically 1/4 wavelength ahead or behind the other
set of elements. So if one line was 1/2 wavelength long, the other line
would be 1/4 wavelength or 3/4 wavelength long, if the horizontal and
vertical elements were at exactly the same spot on the boom. The more
common method is to set the vertical and horizontal elements at 1/4
wavelength different locations on the boom, and then you only need two
feedlines that are exactly the same length. The advantages there include
the fact that phasing lines' lengths need to take account of the velocity
factor of the coax, whereas placing elements at different boom locations is
equivalent to a velocity factor of 1.0 (air).
So how to get the two feedlines exactly equal? Besides lining them up
side-by-side when cutting them, you can connect one end of the cables to a
2-port power divider (or a simple T connector if you aren't worried about
an impedance bump to your signal source), and the other ends of the cables
to the X and Y inputs of an oscilloscope that has X-Y plotting capability.
For two equal lengths, you should get a perfect diagonal line, and if one
cable is a bit longer than the other, you will get a long, slender,
diagonal ellipse. If the cables differ by a full 1/4 wavelength (or 3/4
wavelength), you would get a perfect circle. If the cables differ in length
by exactly 1/2 wavelength, you would get a perfect diagonal line with the
opposite tilt direction as the zero-difference tracing. Googling "Lissajous
Figures" for more information on that gave me the two pertinent links below:

Thank you John, it's all clear to me now. I just hooked a couple of pieces
of coax to my o'scope and sure enough I saw that Lissajous pattern. Clever,

Content-Type: text/plain; charset="utf-8"
Hi All,
The launch time for the Nayif-1 CubeSat has been confirmed as 03:58UTC on
February 15th 2017 on the PSLV C37 vehicle and a set of pre-launch TLEs have
now been released:
NAYIF
1 17002U 17002A 17046.17824931 0.00000000 00000-0 00000-0 0 9993
2 17002 97.5521 107.5843 0004848 278.6481 296.8511 15.21991390 01
This file can also been downloaded from here
http://download.funcube.org.uk/nayif_tle.txt
We expect that the FUNcube transmitter on Nayif-1 will activate at
approximately 05:06UTC, but the exact timing is still to be confirmed!
Initial transmissions will be in ?safe? mode and will be of the 1k2 BPSK
telemetry only with approx 50mW of RF power. If the predictions are correct,
the spacecraft will be heading north over Mexico and the western parts of
the US and Canada.
During the Launch and Early Operation phase (LEOP) of the mission, the
Nayif-1 command team will be headquartered at the American University of
Sharjah Ground station in the United Arab Emirates. They will obviously be
especially keen to have all possible reports of signal reception during this
first orbit! To encourage everyone to take part, there will be a small prize
for the station that submits the first data to the Nayif-1 Data Warehouse
and perhaps an extra reward if they manage to receive the very first frame
transmitted by the spacecraft! This should have the sequence number 5471 or
5472.
Details of the Nayif-1 frequencies, together with details of how to the
download the Dashboard can be found here
https://funcube.org.uk/2017/02/08/nayif-1-launch-date-now-confirmed/
The Data Warehouse is still under final development but a preview can be
seen here: http://data.amsat-uk.org/nayif1/index
Please note that if you are already a registered user of the FUNcube
Dashboard then you do not need to re-register. Your existing details will
transfer automatically to the new Dashboard when you run it for the first
time.
If you run the test file with the Nayif-1 Dashboard please do not expect the
Warehouse to show the data - it is from an earlier date than that is already
displayed. However the ?packets uploaded? tab at the bottom right corner of
your Dashboard will show that the files have uploaded OK, that all is well
with your system and that it is ready for action.
We are hoping that the actual launch will be webstreamed and details of this
will be made available as soon as possible. The AMSAT-UK and -NL team will
also be using the #funcube IRC channel
on launch day and you will be very welcome to join them there. If you do not
have the Dashboard available then please submit your heard reports here. A
web client can be found at http://irc.lc/freenode/funcube if you do not have
an IRC client installed.

The AMSAT NA telemetry server has been taken down while we troubleshoot an
issue. We will let you know when it is back up. For now telemetry will be
held by FoxTelem until the server is available. This shows as "Queued" in
the bottom right of the window.
You will not see telemetry update at www.amsat.org/tlm or be able to query
the latest health of the spacecraft until the server is back up.
I'm happy to answer any questions.
