On the IC-W32A's... I read several places that the early ones with 5 digit
serial numbers are okay, but that is not necessarily true from my
experience. I bought two of them with five digit numbers over 11000 and
still had the desense problems. The determining factor, as best I can tell,
is if it receives in the 300 Mhz and 800 Mhz bands then it's possible it
doesn't have the desense problem.
Just FYI for anyone looking...
And I think you can ad IC-Z1a to that list. I found a pretty good list of
older compatible rigs here, not just HTs but all rig:

Another point to consider is you can buy two of the cheap Chinese HTs for
about what the diplexer in the Arrow costs. That's the cheapest way to get
to full duplex.

If there were a market for them they'd be out there. I think the amount
of people who want to work Flying repeaters by juggling an HT and a
handheld antenna is smaller than what that type of operations proponents
would have you believe. Not saying there is anything wrong with doing it
that way, just that I don't think it's as popular as it once was. Maybe
the current lack of flying repeaters is the cause. There is a dearth of
all mode base station rigs compared to what there used to be too because
there aren't as many viable satellites as there used to be. Hopefully
that changes soon enough. I know AMSAT is working hard to launch more
sats. Well....more flying repeaters anyway.

Great point, Drew.
KD2EXR does a great job on SO-50 with two Baofeng UV-B5s. Check out
his QRZ.com page.
His entire FM satellite station cost under $100 and he seems to hear
just as well as anyone (probably better than most, actually).

Sure, now you tell me that after I buy the Arrow with the diplexer! =^D? But
seriously, I bought a used Arrow that already had the diplexer, however I
have done just as you suggested... I bought a second Baofeng and a couple of
BNC jumper cables. Now I have to sort out splitting to headphones and my
recorder both.

It's probably not as popular because SO-50 is harder to hear than
AO-51 or AO-27 were. I'm sure lots of people will be trying it again
when Fox-1 launches in December.
And, as you know, AMSAT is not working on launching only more "flying
repeaters," but also software defined transponder satellites as well
(Phase II of the Fox program). Other groups, including AMSAT-UK,
AMSAT-NL, and AMSAT-F are also working to get transponders into orbit.

NASA, SpaceX Officials Continue Preparations for 14 April Launch
NASA and SpaceX officials decided this morning to continue
preparations for launch of a commercial resupply run to the
International Space Station on Monday after a computer failed aboard
the complex Friday, but managers will meet again Sunday morning to
make a final decision on whether to proceed with the launch.
The failed computer, called a multiplexer-demultiplexer, or MDM,
provides redundancy for the space station's mobile transporter, part
of the outpost's robotics system that allows the Canadian-built robot
arm to move along the lab's truss backbone.
The robot arm will be used to grapple the SpaceX Dragon spacecraft
when it arrives at the space station. In a statement issued Saturday,
NASA said the Canadian-built robot arm has other backup capabilities
not affected by the failed computer.
NASA says the failed MDM is known as "EXT-2" and measures 10.5 x
14.9 x 16.4 inches and weighs 50.8 pounds. The computer failed during
a routine health check of the device, according to NASA.
"Station program officials, flight controllers and teams of
engineers are working to determine whether there is any risk to
launching the SpaceX cargo craft Monday," the statement said. "They
will evaluate whether the station has enough redundancy to permit the
launch to proceed."
NASA says a separate team is planning a contingency spacewalk to
replace the failed computer box, but no date for the spacewalk has
been set.

---------------------------------------------------------------------
KickSat CubeSat to Deploy Smallest Earth-Orbiting Satellites
When the third SpaceX ISS resupply mission launches on April 14 from
Cape Canaveral, it will carry the 3U KickSat CubeSat into orbit. NASA
TV is scheduled to broadcast the launch live. If all goes according
to plan, KickSat, in turn, will release 200 "Sprite" satellites --
each about the size of a small cracker -- into orbit. They will become
the smallest Earth-orbiting satellites ever. Zac Manchester, KD2BHC --
a Cornell University PhD student in aerospace engineering -- is
heading up the project, which was funded via Kickstarter.
"Our goal is to dramatically lower the cost of spaceflight, making
it easy enough and affordable enough for anyone to explore space,"
the KickSat project website proclaims. "We can do this by shrinking
the size and mass of the spacecraft, allowing many to be launched
together."
The tiny Sprite spacecraft will be single-function, short-lifespan
units operating on 437 MHz. Each is essentially a double-sided
printed circuit board measuring 3.5 cm ? 3.5 cm, incorporating a
microcontroller or two, radio, and solar cells. Each can carry single-
chip sensors, such as thermometers, magnetometers, gyroscopes, and
accelerometers.
All Sprites operate on the same frequency -- 437.240 MHz -- and use
Code Division Multiple Access (CDMA). Transmitters run 10 mW output
of minimum shift keying (MSK) modulated binary data, with each data
bit modulated as a 511 bit pseudo-random number (PRN) sequence (The
ITU emission designator is 50K0G1D).
Andy Thomas, G0SFJ, points out that the Sprites will only operate
when in sunlight. "Characteristically they have a 60 kHz bandwidth,
and so narrowband receivers are not of any use to receive them," he
explained in a tutorial that describes plans for a simple Earth
station. "Therefore, the receiver of choice is a software defined
receiver."
When KickSat reaches orbit, it will perform a "de-tumble" maneuver
and establish communication with Cornell University's ground station.
After everything has been checked out, the spacecraft will be put in
a sun-pointing attitude and spun up to maintain that attitude. Then a
command signal from the ground will trigger deployment, and the
Sprites will be released as free-flying spacecraft. The Cornell
ground station in Ithaca, New York, will monitor telemetry and sensor
measurements from the individual Sprites, with assistance from
several other Amateur Radio ground stations around the world.
Due to their low orbit, the Sprites will have short lifetimes,
perhaps as long as six weeks in a best-case scenario but possibly a
lot shorter, depending on atmospheric conditions.
KickSat is being planned as a technology demonstration mission for
the Sprite spacecraft. It's being launched through NASA's Educational
Launch of Nanosatellite (ELaNa) program. The KickSat project was
founded in 2011 by members of the Space Systems Design Studio at
Cornell University and is an outgrowth small spacecraft research that
has been conducted there since 2007.

AMSAT at the Dayton Hamvention - 2nd call for volunteers
The Dayton Hamvention is less than five weeks away!
It is time to be creating your shopping list and making your travel
plans. If you can stay for more than a day and you want to stay with
at the AMSAT hotel, contact Martha ASAP.
Last year, we had 41 people assist with the AMSAT booth at the
Dayton. We've had a good response so far to our call for volunteers,
but we could really use another 10-15 people. The interaction with
AMSAT members, satellite operators, designers, and builders makes the
whole experience a lot of fun. Meet or renew acquaintances, exchange
operating tips, and find out what antennas, software and equipment
other AMSAT members use. We currently expect all of the AMSAT senior
officers and 6 of the 7 board members to be there too.
The 2014 Hamvention is May 16-18. Would you consider helping AMSAT
at Dayton this year?
If you're an experienced operator, great! We can use you and your
experience.
If you've never operated a satellite before, but want to learn more,
that's OK. We can use your help too.
Whether you're available for only a couple of hours or if you can
spend the entire weekend with us, your help would be greatly
appreciated.
Please send an e-mail to Steve, n9ip at amsat dot org if you can
help.
Thank you!

FUNcube/AO-73 Transponder plans for the future
Following the 48 hour test last weekend, we have concluded that the
battery temp does reduce slightly during full time transponder mode,
but only by a degree C or so; it remains within specification. Hence
we have decided in future to switch the satellite into 'forced
eclipse mode', ie full time transponder and low power beacon at
weekends. The aim is tosignificantly increase the availability of the
transponder to radio amateurs. We will continue with this plan until
further notice.
We plan to switch to full time transponder mode during the first
suitable pass over the UK on Friday evenings, normally between 19:30
and 22:30 UTC. If for some reason this is not possible, then the
switch will be done on the first suitable pass on Saturday, normally
between 09:30 and 12:00 UTC. We plan to switch the full time
transponder mode off during a suitable pass on Sunday evenings (UK
time), which normally occur between 1930 and 22:30 UTC. Again, if
this is not possible the switch off will be made on Monday mornings,
approx. 09:30 to 12:00 UTC.
Do PLEASE NOTE that this schedule is totally reliant on the
availability of command stations, who will do their very best to
ensure it is maintained. We will not normally announce successful
full time transponder mode on/off commands, but if it proves not
possible to make one of them, then we will make a note here and on
the FUNcube web site at
www.funcube.org.uk/news.
So please do enjoy the transponder, and use it any time you hear it
on. We are always pleased to hear of your activity, so either leave a
comment on the website, or email g3wgm -at- amsat.org.

ARISS News
Due to Koichi Wakata's, KC5ZTA, increased work load beginning 2014-
03-11, ARISS has had to move 3 schools back to our long term waiting
list. We hope to get to them in the fall of 2014. There are also
several other schools that are on the list for possible postponement
to the fall.
>From 2014-05-12 to 2014-06-15, ARISS will be going into a period of
no contacts as there will be no hams onboard.

+ Make a #GlobalSelfie with NASA on Earth Day
NASA invites you -- and everyone else on the planet -- to take
part in a worldwide celebration of Earth Day this year with the
agency's #GlobalSelfie event.
The year 2014 is a big one for NASA Earth science. Five NASA
missions designed to gather critical data about our home planet
are launching to space this year. NASA is marking this big year
for Earth science with a campaign called Earth Right Now, and as
part of this campaign the agency is asking for your help this
Earth Day, April 22.
While NASA satellites constantly look at Earth from space, on
Earth Day we're asking you to step outside and take a picture of
yourself wherever you are on Earth. Then post it to social media
using the hashtag #GlobalSelfie.
See details at

If the Kenwood is full-duplex, why don't they claim that anywhere in their
literature?

No idea why it's not in the literature, but it definitely is full duplex,
just like the earlier models of the D7 series.
