One more comment (and not contrary to what Bob is saying):
For us at far north latitudes, ISS never rises very high (about
11-deg. max), so using a high gain vertical works well with ISS which
is always near the horizon. I worked Bill MacArthur in 2005 using my
9-dB cushcraft 17-foot base whip running only 50w. But for polar
orbiting Leos this is not good.

Dear friends,
This morning I have uploaded a new High Definition (HD) video:
http://www.vimeo.com/4911267
COMPASS-1 is the first CubeSat of the Aachen University in Germany.
It is a 10x10x10 cm cubic satellite with a mass of less than 1 kg.
Daily download of satellite data is delegated to a team of radio amateurs
around the world. (btw I am not one of the active members, only just a
back-up station)
In this video it is demonstrated how satellite data (telemetry) is
downloaded using 1k2 AFSK modulation.
Maybe this video can make others also enthousiastic to start looking into
Compass-1 or other Cubesat programs running today. If so; take a look
here for some commands: http://www.raumfahrt.fh-aachen.de/news.htm
To me it shows Amateur Radio is very exiting, and satellite operations are
way cool ! Yes, these Cubesats are no replacement for HEO's, but they
do challenge me (just getting your station non-stop, fully automated
running sounds easier as it is)... and HAM radio is all about challenges
and experiments, that's what makes it fun and keeps it interesting for me !
To play the movie full-screen, click on the right bottom button in the player.
Also there is a HD button, ensure it is showing "HD is on".

Hello all,
On 05/28/2009 around 20:39 and 20:40:30 UTC in the 58029 orbits AO7. I
heard the station, Jean-Jacques, ON7EQ - in GI84ow - 4757 (Miles) or
7616 km. Unfortunately I can not contact due to problems in my uplink. I'm
manually controlling the uplink and that made it difficult to contact. All
contact
via satellites that I hear, are routinely recorded. A small part of the
audio of Jean-Jacques, ON7EQ via AO7 was added on youtube, the audio is
not in good quality. For me it was fantastic in the case of a signal
via AO7. I hope soon to maintain contact with our friend Jean-Jacques in two
ways.
I hope you enjoy it.

Hi Shamai,
You will need to download the following files in the same location as the
telemetry program:
http://www.dk3wn.info/files/ocx.zip
And, you might need this: http://www.dk3wn.info/files/vbrun60sp3.EXE
Mike links these at the top of his telemetry page...lots of decoders! And
you'll need these for them.
Hope that gets you up and running!

Bob,
It is only significant if you are in QSO when it happens, but needs to be
listed when comparing antenna types.

But that is quite insignificant. Looking at the gain plot of a 3/4 wave
vertical (the 19.5" whip on 70cm) it is only down say 6 to 10 dB above 85
degrees. BUT the satellie is 10 dB or more closer when it is above 50
degrees which more than makes up for any loss of gain straight up. see
plots on
www.aprs.org/rotator1.html
But yes, there can be a complete fade when it is perfectly directly overhead
(extremely rare). But since the satellite is only above 50 degrees only 5%
of the time, it is only above 85 degrees only 1/8th of that 5%, or much less
than 1% of all access times. Again, losing less than 1% of access time due
to a possible less than 1% chance of a fade is nothing to be concerned
about. Just 2 cents worth...

Greetings. Ok so this issue gets revisited every few months or so-- as it
seems. I have a nice list of many fully duplex VHF/UHFradios-- I forget who
put together-- that list is taped to the wall next to my station. This comes
in handy for shopping on eham, ebay, etc. However, I am wondering if it needs
some updating. No clue here. Maybe it is current. Ok well almost. I know
it does not list the new Alinco DJ-G7.
Ok so the main reason for the post is first to ask (for the hums): does the
Kenwood TH-F6A operate in fully duplex mode? the reviews on eham were not
exactly clear on this point. If so, then any peculair problems SO
The second reason for this post is to ask if anyone perhaps has a more up to
date/complete list of truly duplex radios (ie, can do sat work!) ;-)
Thanks and 73s

Hi,
I'm looking for any comparison which frequency select for cubesat
(command, telemetry).
I know that many of designers used UHF UHF, but link budget margin
that better to use VHF - smaller path loss for about 10dB
what are the main reason for use UHF --> antenna size, free frequency
on UHF band, other losses, ground station antenna gain or ??
Thanks for help and comments,
best regards Andy

The TH-F7E (which is the European version, with 220MHz transmit
disabled) doesn't do full duplex.

The new Alinco is the only current-production HT that offers full duplex
operation. Kenwood's TH-F6A is not a full-duplex radio.

After several years of running the AMSAT-UK shop,
Jim G3WGM has handed the reins to Ciaran Morgan M0XTD.
Ciaran obtained his full license in April
2008 and enjoyed organising a very successful ARISS
contact between Budbrooke School in Warwick, England
and Richard Garriott K5KWQ whilst he was onboard the
International Space Station in October 2008.
The AMSAT-UK shop has been an important source of funds
in the past and Ciaran is revamping the current shop to
help it to continue to make a valuable contribution to
the funds into the future. The shop has had a policy of
only stocking items that are difficult to obtain in the
UK and, initially, that policy will remain whilst Ciaran
gets familiar with the stock and identifies other
possible options.
Suggestions are always welcome and a new email address
(amsat-uk-shop@xxxxx.xxxx has been setup. Please send
the suggestions in and keep checking the web site for updates.
Due to the level of sales of software, and compatibility
issues with the more recent Microsoft Operating Systems,
it has been decided to stop selling InstantTrack and
QuickTrack. WiSP and SatPC32 licenses will continue to
be issued from the shop Also, there are currently no books
for sale - we are looking at this but suggestions are
always welcome.
On the hardware front, we have restocked with the ever
popular LVB motherboards and we also have a limited number
of complete kits for the LVB Tracker unit. Half of the new
kits also include the AMSAT-NA enclosure with compatible
display unit! We are also investigating restocking the
2.4GHz signal sources from G0MRF and the G7HIA 2.4GHz
patch kits - please keep a watch on the website for
more details.
The AMSAT UK website can be accessed via http://www.uk.amsat.org/
- the shop is accessed via a link on the left
hand side of the web page.

AO-51 will be configured for Field Day with dual repeaters,
1268.700/435.150 and 145.920/435.300. No PL tone is required.
Please note that the 435.150 downlink is left hand circular
polarized, and the 435.300 transmitter is right hand circular
polarized. This configuration will be available for the week
preceding Field Day, through the Field Day weekend
(June 22nd-28th, 2009).
AO-7 has returned to experiencing short eclipses each orbit,
thereby preventing the 24 hour timer from switching modes.
AO-7 has been observed to favor Mode U/V (B) almost
exclusively during these periods. Please check
http://oscar.dcarr.org/ or
http://www.planetemily.com/ao7/ao7log.php for
the most recent reports of the current mode.
GO-32 still in bootloader status, return of the BBS is unknown.

FRANK BAUER, KA3HDO, RECEIVES ARRL PRESIDENT'S AWARD
On Saturday, May 16 during the forum featuring Richard Garriott, W5KWQ, at
the Dayton Hamvention, ARRL President Joel Harrison, W5ZN, presented former
Amateur Radio on the International Space Station (ARISS)
<http://www.rac.ca/ariss/oindex.htm> International Chairman Frank Bauer,
KA3HDO, with the ARRL President's Award. Bauer, who stepped down from ARISS
<http://www.arrl.org/news/stories/2009/03/25/10724/> and Radio Amateur
Satellite Corporation's (AMSAT) <http://www.amsat.org/> duties this past
March, served as ARISS Program Leader and ARISS International Working Group
Chair. Since 1991, he served as AMSAT Vice President for Human Spaceflight
Programs.
The ARRL Board of Directors voted to create the President's Award in 2003.
The President's Award is to go to an ARRL member or members who "have shown
long-term dedication to the goals and objectives of ARRL and Amateur Radio,"
and who have gone the extra mile to support individual League programs and
goals. Nominations for the award come from directors and are approved by the
ARRL President and the Executive Committee.
Under Bauer's leadership, Amateur Radio activities have been on human
spaceflight vehicles, including NASA-sponsored ham radio activities on the
shuttle, Space Station Mir and the ISS. Starting in 1983, Bauer led the
Goddard Amateur Radio Club team that provided around-the clock space shuttle
retransmissions from the WA3NAN club station. These retransmissions provided
the international ham radio community up-to-the-minute information during
the flight of Owen Garriott, W5LFL, on STS-9
<http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/archives/sts-9.ht
ml> and subsequent SAREX flights. In the days prior to the Internet, these
real-time bulletins and frequent orbital element updates could only be
obtained through Amateur Radio.
"For well over a decade, I have been fortunate to be part of a group that
has been leading international teams together to focus on Amateur Radio on
the ISS," Bauer told the ARRL. "As AMSAT Vice President for Human
Spaceflight since 1991, I have really worked to get this international team
to work as one, focusing on Amateur Radio. It is very critical to get all
the space agency partners to have a vested interest in making sure we do
Amateur Radio right on the ISS. We need to keep the partnership we have with
our international team in good stead."
