Thanks everyone for the input. I think I will go without a counterbalance,
per Mike K9QHO, and see how it goes.

Message to US Educators?
Amateur Radio on the International Space Station?
Contact Opportunity?
?
Call for Proposals?
New Proposal Window is October 1, 2019 to November 30, 2019?
?
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS.? ARISS anticipates that the contact would be
held between July 1, 2020 and December 31, 2020. Crew scheduling and ISS
orbits will determine the exact contact dates. To maximize these radio
contact opportunities, ARISS is looking for organizations that will draw
large numbers of participants and integrate the contact into a
well-developed education plan.?
?
The deadline to submit a proposal is November 30, 2019.? Proposal
information and documents can be found at http://www.ariss.org .?
?
The Opportunity?
?
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.?
?
An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight
and the complexity of scheduling activities aboard the ISS, organizations
must demonstrate flexibility to accommodate changes in dates and times of
the radio contact.?
?
Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations' volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students around the world using
Amateur Radio.??

Message-ID: <1188124F682E4BF8A943E56F7D6BF9CE@?????????>
Content-Type: text/plain; charset="iso-8859-1"
An interesting thread just started over on Twitter on When and Why there is
an experimenters day.
I thought this discussion ought to be on this AMSAT group also.
Let me first try to capture some of the initial Twitter tweets:
WD9EWK
AO-92 L/V @ 1801 UTC Wednesday: Nice pass for central Arizona, TNX @??????
@????? for QSOs.
Fewer showing up for weekday L/V out here, day and night.
WY7AA
I believe that it should be in L Band for 48 hours during the week for a
period (say 3 months) and then 24 hours on the weekend for the same.
Everyone gets some time with it then, and people can complain when they
forget it changed.
WD9EWK
With AO-51 in the past & its different configurations, it was usually left
in something like V(USB)/U(FM), V/S, or L/S for a week at a time. Not just
one day at a time. Made it easier to try the different configurations when
they were available.
WY7AA
I don't have an answer based on your choices. I believe that it should be in
L Band for 48 hours during the week for a period (say 3 months) and then 24
hours on the weekend for the same. Everyone gets some time with it then, and
people can complain when they forget it changed.
Lets have a discussion on the AMSAT-BB also.
I find changing times not ideal for me but others would prefer different
times. Such as weekend vs. Weekday.
Perhaps a mailing list which would be sent out as a reminder.

As I understand, AO-7 will begin doing 24 hour mode switches about now. So
I went to the status page on AMSAT.org and see that the Mode A listing is no
longer there. Since it was in a long period of eclipse shutdowns, probably
got dropped inadvertantly. Also looking forward to learning when the switch
time is nailed down.

If I may, this seems a good opportunity to present a little background
on Fox-1 L band.
The L band uplink capability on AO-92 and AO-95 (sobsob) are in fact, an
experiment called DOWNSHIFTER.? Just as we fly partner experiments in
the "top" four PCB positions of the Fox-1 avionics stack, DOWNSHIFTER
occupies the EXP4 slot in Fox-1C and Fox-1D.
When Fox-1C/D were assembled, the EXP4 was available as it had been on
Fox-1A.? Fox-1A was of course the first flight, and it had a minimal
payload because of the inherent uncertainty in any first flight.? Fox-1C
consists of the flight spare Vanderbilt University radiation experiment
from Fox-1A and one of the two Virginia Tech camera experiments.? Fox-1D
consists of the University of Iowa HERCI experiment and the other
Virginia Tech camera experiment.? In both cases, although the VT camera
"peeks through" a slot in the EXP4 PCB, the EXP4 was vacant.
We were kicking around the idea of maybe flying our own (AMSAT or AMSAT
Engineering) experiment of some sort in order to populate the EXP4 slot
on C and/or D, after the completion of Fox-1A.? With the purchased
launch of Fox-1C and D (at that time) coming up in short order we did
not have a lot of time to spend looking around for ideas.? John
Klingelhoeffer WB4LNM came up with the design idea for an L band uplink
capability made possible by down converting the 1267.x MHz uplink signal
to the 435.x assigned UHF uplink for the bird and passing it to the
receiver input.? It fit the bill of the smaller real estate available
due to the camera notch, the mechanical limitations of EXP4 volume (less
than the other three EXP slots because of the +Z solar panel right
above), the need to function with the existing standard Fox-1 antennas,
and the slim power budget of the Fox-1 birds "fully loaded".? John
dubbed it "DOWNSHIFTER" and we went for it.
Being less complex than an entire repeater or transponder made for
somewhat faster fabrication to make the C/D deadline (C/D were
originally booked to launch together on the same LV) and both birds were
outfitted with a DOWNSHIFTER.
DOWNSHIFTER was/is an experiment, given the new (to the 1U CubeSat form
factor) design and uncertainty of the performance of the UHF antenna at
12xx MHz among other things.? As such it was treated as all experiments
are, with an overruling control by IHU and hardware that protects the
bird from a runaway experiment.? Pretty much, it's called an experiment
and not a system (like the rest of the avionics stack) for a reason.
For that reason we assigned a 24 hour timer to the activation of L band
mode in order to protect against the bird being in L band and deaf,
whether due to the antenna not being so hot at 1267.x MHz or DOWNSHIFTER
failing to shift down, any malfunction that would prevent the UHF
receiver/transponder from hearing a command station.? By use of the
timer, if all was well then 24 hours was a good period of operation for
ops around the globe and in the worst case if it didn't work, the bird
would be back in UHF mode and under command control within 24 hours.?
The 24 hours is required as part of the imaging device license and an
FCC order to cease transmission.
We are blessed and I was totally jazzed that the DOWNSHIFTER worked
quite well in commissioning on AO-92 and continues to do so.? We took
DOWNSHIFTER into consideration as a point of failure in AO-95's woes and
did tests exploring that.? While -95 is deaf in any of its assigned
bands the 24 hour timer would protect if we were able to command it to L
band which offered the designed comfort to be able to try that if it was
a possible path in troubleshooting.
I will not enter into any discussion of the scheduling of L band mode or
the use of any of the satellites as that is entirely up to Ops when the
leave Engineering's hands at commissioning.? I did think it might be
useful to give some history on the why and how of L band on AO-92 and
AO-95 (sobsob) for your discussion.? Have fun with the birds whatever
their mode and your style of operating, that's what makes my day!

Tom,
According to ILLUM, the last eclipse was 1 minute on 10 Oct, and the next
eclipse will be 1 minute on 1 December. PREDICT presents things slightly
differently, and gives the period of full illumination as 9 Oct to 2
December.
Apparently a status line times out if there is no data for a period of time,
but not the dropdown box. Just for fun, I put in a Not Heard report, and
the Mode A status line is back. Who knew?
73,
Alan

<As I understand, AO-7 will begin doing 24 hour mode switches about now. So
