Enzo,
It has been switched to the transponder mode, so it is not currently sending
telemetry. I had a pass near the horizon today, and heard the downlink with
someone calling CQ.

Hi Francesco, IW4DVZ
and All to the list
While SV1BSX was decoding the TLM during orbit 59018 I was in contact all
the time in SSB with i6IBE and IW6OVD during the full eclipse and no other
people was operating the transponder so that we piked up the following
power supplied only by the batteries of FO-29
844.4 mW
265.9 mW
746.9 mW
707.9 mW
Please note that before to enter the eclipse the solar panel were well
illuminated with a sun angle of 72.5 degrees and probably they were
fully charged but during the eclipse the solar panel current dropped
down to only 9.8 mA
It seems that FO-29 is working nominally and no difference on signal
strenght was observed in comparison to the operation in 2007
With the help of Morfeo I plan to test again the ECL this night during
the South-bound orbits 59031 and 59032

You're right, Seattle should not be hard on AO-7. There's even some
theoretical overlap of 0.8 minutes from the Shetlands to Redding,
California (thus 49 states), but you'd better have good horizons and
a good receiving setup. I'll be seeing if that much overlap might be
enough to make it to Alaska on AO-51 (as Iceland has been worked from
there without sked).
What it really came down to was size/weight and how to compensate for
doppler on the uplink, as the SSB rig that i've been offered doesn't
have computer control. Even if it did, there are too many software
issues to solve prior to travel and i'd need to take the docking
station (nearly doubling the computer's weight) if i needed a real
serial port. But what it really comes down to is that don't want to
carry any more weight (that is assuming the rig[s] would even fit in
my luggage), as it does not make sense to have a car for the third of
the trip that we're in Edinburgh or Glasgow. So unless someone in the
SF Bay Area (or Scotland) can offer a better idea, higher orbit LEO's
won't happen this trip.
> "if this were easy, everyone would be doing it"
Yeah, maybe next trip i'll have access to suitable equipment. I've been
talking to another local ham about a small dsPIC-based SSB transmitter
and/or receiver. But even if hardware existed a month ago, it's unlikely
the software issues would have been solved in time... It's too bad that
Yubileiny doesn't have mode J-FM. Maybe someday someone else can put up
something more useful into that kind of an orbit.

John,
Sure, I'll "shoot the Atlantic" with you. I'm assuming you'll bring
equipment to work the FM LEO(s). If so, I've worked several stations in
various parts of England and one in Madrid, Spain on AO-51. AO-51 would
be my FM LEO of choice for this.
I live near Binghamton, NY where I have a hillside location about 500
yards up behind my house with an excellent view. From this spot I can
work AO-51, and other FM LEO(s), down to 1 degree above the
northeastern horizon. In fact, anyone who can get to the seashore in
the eastern U.S., from New Jersey to Maine, should be able to do this.
Canada's Atlantic provinces and Newfoundland are even better. All you
need is a clear shot across the Atlantic Ocean to the northeast to
access AO-51 while its also in view of the extreme western edge of
Europe.
To connect Europe to North America on AO-51 will, of course, require an
AO-51 pass down the center of the Atlantic. This means you'll be
working a pass with a maximum elevation of 1 or 2 degrees, as will I.
My experience has been that such a pass will give us a 30 to 60 second
time window during which we can exchange call signs. So when the time
comes, you'll need to call me often for several minutes to hit the time
window just right. I'll do the same. Perhaps if pass conditions are
perfect, we may get a couple of minutes.
In addition, in light of the comments above, I recommend you try this
from the west coast of Scotland with a solid view across the Atlantic
to the southwest. Be advised, the west coast of Scotland can be
extremely windy, so come prepared.
Also, I know you be operate QRP. But bring as much transmit power as
you can. With a pass down the center of the Atlantic, AO-51 will be
approximately 2000 miles away from both of us. My experience is that 5
watts to AO-51 at this distance is "iffy". I'll be running 50 watts, so
I'm pretty sure you'll hear me as others have before.
Since I'll have to drag my portable station into position, we'll have
to pick out an AO-51 pass and set up a schedule, or two (back-up),
off-line. Good Luck!
-Richard, N2SPI

Hi Enzo,
Yes, DO-64 is alive in this part of the world operating in transponder mode
(145.900 downlink).
Just completed pass at 2034 UT had good transponder downlink signals and
good beacon signals.
Look for the beacon around 145.870MHz

Hi all,
DO-64 pass over ZL/VK at 2211UT showed an interesting effect. I was in
contact with VK2AYE and VK2ZAZ when the signals effectively disappeared some
minutes before LOS. VK2AYE checked the beacon and reported that it was
badly distorted at that time. I noticed the same effect on a previous pass
on my own downlink and also saw another pass when the beacon was distorted
for about a minute. The effect is identical to the distortion seen on the
data channel and occurs when Delfi is South of ZL and starting to loose the
sun. It lasts for about a minute or so and then recovers.

Enzo,
It works like AO-7, AO-10, and AO-13. Take a look here:
http://tinyurl.com/5cgkpc Reports are that the pass band is shifted
slightly, with 435.556 uplink corresponding to the 145.900 downlink as the
center of the pass band.

elevation to track the selected satellite when it is or above your horizon. In
addition, if you have a radio with a computer interface, the TrakBox will tune
your transmitter and receiver and correct them for doppler shift. TrakBox is
set up to directly interface to Kenpro, Emmoto, and Yaesu dual-axis rotators
which include a computer interface. Trakbox includes a serial port to allow
you to set the real-time clock (which is battery backed), your station
location (latitude, longitude and elevation) and the keplerian elements for
the satellites you are interested in (up to 40 satellites may be loaded, and
the elements may be uploaded in ASCII in either the AMSAT or NASA formats). A
two-line LCD display is updated every second, showing the azimuth and!
elevation of a satellite, along with the satellite ID and GMT.

I built this kit from TAPR back in the late 1990's. It provided excellent
service. Still works fine. Asking $130.00, OBO

HI folks,
I am selling a new KJ6KO 23cm amplifier. 6 watts in will get you around
70Watts out. Ideal amplifier for the 10 watt 23cm units in your TS2000X,
IC-910 and FT736 etc. The amplifiers comes with the matching ASTRON LS-10A
power supply.
Both together for $300, shipping extra (payment via PayPal).

Thanks Doug, for sticking with my puny signal through two passes to make the
QSO on AO-7 tonight. I was using a FT-817, Arrow antenna, and SATPC32, while
portable on the bank of the Resurrection River just down from Exit Glacier
in BP50, Seward, AK. I've been on a few AO-51, AO-27, and SO-50 passes from
up here and made a handful of QSOs despite the mountains and trees, but this
AO-7 QSO was tops.

I have used my FT-897 with an hardware TNC (TNC7Multi), and I have no trouble
receiving 9600 bps telemetry from AO-51 and packets from GO-32. My radio was
in
PKT mode and I set the PKT Rate menu option to 9600.
It's important to follow the manual and connect to the 9600 bps pin on the
Data
connector and not the 1200 bps pin. The 1200 bps signal is the processed audio
after filtering, where as the 9600 bps signal comes right off the radio's
discriminator. The audio filters are too narrow for the 9600 signal.
Good luck.
73,

Hi Wouter Jan,
Congratulations !
As HAM radio amateurs we all have enjoyed to cooperate & contribute to this
scientific/commercial first part of the mission for (amongst others) the
following reasons:
- your very transparant communication on status (pre and post launch)
- a prompt Q&A handling by the command team
- telemetry decoding SW very easy to use & install (+ auto telemetry
forwarding)
Please keep us posted on the conclusions of the mission and the lessons
learned... and we have also learned, as we do from each new satellite.
Observing the tumbling (rotation rate) for example was interesting, as
well as trying to figure out the on/off switching as a function of the
telemetry.
What I found to be improved in my station/set-up after this was the following:
Delfi C3 had a drift in frequency during a pass, which was predictable.
However, automatic doppler correction SW does not provide today an option
to insert functions for additional frequency drift. This blocked me in
having my station running 24/7 to monitor Delfi C3 (as I needed to correct
the frequency manually a bit during a pass), sorry for that. It is something
for me to think about how to improve.
The transponder is working well and the receiver uplink is sensitive.
Yesterday evening I made a short QSO with SP9FPP:
http://www.pa3guo.com/delfi_c3_30jul08_1955utc_sp9fpp_pa3guo.mp3
(distortion in the 1st part of the mp3 is due to my recording, the sat is
great)
A big thank you for the given opportunity to the HAM radio community to
contribute to your project, and of course: THANKS FOR THE TRANSPONDER !
73s, Henk, PA3GUO
