Hello Everyone,
The 2010 Symposium Schedule is posted on the amsat.org web at:
http://www.amsat.org/amsat-new/symposium/2010/SymposiumSchedule.php
A few minor tweaks may be necessary over the next 7 days. The final version
will be available on-site at the Symposium next week. Authors and presenters
will be e-mailed any schedule change affecting the talks.

Hello All,
The reloading of AO-51 is essentially complete; the bird is in good order.
A side effect of the crash/reload is that the mode change to S-band has been
delayed--until now.
We are going to resume the scheduling of AO-51 with the following changes:
the power budget should allow the simultaneous operation of both the S-band
and U-band transmitters. The tradeoff is that the U-band will be low in
power-around 250 mW or so.
Also, please notice the use of the 145.880 MHz uplink!
This is a great time to work on improving the sensitivity of your receiver
setups! The 250 mW will challenge some of you for sure. PLEASE be sure to
follow the "if you can't hear it, don't try to uplink" basic rule of
satellite operation.
If the satellite supports the dual downlink mode OK, we may extend the V/S-U
mode a few days past the original mode schedule in order to give mode S
operators a fair shake at some operations and testing--while at the same
time allowing some low power mode V/U operations!
September 29 (around 2120 utc)
FM Repeater, V/S-U
Uplink: 145.880 MHz FM (no PL tone)
Downlinks: 2401.200 MHz FM *and* 435.300 MHz FM (at low power!)

Hi Bob... I must have problems. I could not hear my down link. I am
sorry if I stepped on others
while making my calls. I am using a K5GNA 3731AA down converter. It is
the same one I used for
AO40. I tuned the down link frequencies on 2m and I heard my signal
however I think it was a
harmonic since I could copy it after the satellite went out of
footprint. My 2.4g signal scource is not working so could not check it out.
Good to hear I was getting out. Need to make adjustments here. I
will be going to the AMSAT
Symposium next week.
Thanks for letting me know about signal.

My July/August 2010 issue of The AMSAT Journal arrived today and I was
pleased to see the article by Alan Biddle on Doppler Tuning. This has long
been a pet project of mine since Paul Williamson, KB5MU, published his
article "The One True Rule for Doppler Tuning" in the OSCAR Satellite
Report, January 1994 and my article "A Recommendation for Doppler Tuning" in
the March/April 1996 issue of The AMSAT Journal.
I was especially pleased by Alan's call for satellite tracking programs that
control your transmitter and receiver to display the "frequencies at the
satellite." This should be very easy for the developers of the software to
do. For example, in SATPC32 (an ad for which appears on the last page of
Alan's article), the "frequencies at the satellite" are almost displayed
now. In the center of the window, just below the menu bar, are displayed the
Receive and Transmit frequencies (at your location) and just below these are
the Doppler correction values from the "frequencies at the satellite."
Algebraically subtracting the lower (Doppler correction) value from the
upper (your site frequency) values yields the "frequency at the satellite."
It would seen to me that the program should display the "frequency at the
satellite" as the frequency of your receiver and transmitter are most likely
already displayed on your rig. How about it, you software developers? At
least give your users the option of which value to display in your window.
As an aside, speaking of Doppler shifts, I (along with K5EWS and others) are
currently working on a method of tracking model rocket flights using an
inexpensive UHF transmitter (925 MHz CW in my test case) in the rocket and,
using several receiver sites, analyze the Doppler shift of the transmitted
signal and use the mathematics of Trilateration to determine the location of
the rocket in 3-space. Our first full scale test is this coming weekend.

September 2010 marks the end of my first year on the satellites and I have
had a great time meeting new hams and working the birds. I have a modest
station consisting of two omni-directional egg beater type antennas mounted
on the eave of my roof, mast mounted pre-amps and an IC-910H. During the
year I have been able to make 2,036 contacts distributed as shown below:
AO-51 709 ( 34.8% )
AO-27 237 ( 11.6% )
HO-68 273 ( 13.4% )
SO-50 203 ( 10.0% )
SO-67 8 ( 0.4% )
FO-29 248 ( 12.2% )
VO-52 222 ( 10.9% )
AO-7 133 ( 6.5% )
ISS 3 ( 0.1% )
I have managed to work 49 states with 48 confirmed (missing HI & WV), and I
have about 250 confirmed grids.
I want to thank all of the hams that helped me along the way. Their great
suggestions and patience is very much appreciated. I?d like to extended
special thanks to Allen ? N5AFV for my first contact on satellite as KE5EQZ,
and John ? K8YSE, Jim ? ND9M, Pat ? WD9EWK, Kerry -WC7V and Larry ? KI6YAA
for the numerous contacts and the many new grids that I acquired during
their Grid Expeditions.

Dear Dee asked her team of "ARISS Area Coordinators" last week for a brief
explanation of "what we were doing on behalf of AMSAT and ARISS. I
immediately replied to her, citing the number of presentations I have made
... and the number of demos accomplished - numbers that could have been
interpreted as "self-promotional" numbers. But they were submitted to her as
not to promote "K6LCS," but to try and show what was happening in Southern
California on behalf of ARISS and AMSAT.
But today I received two email messages that made me feel great for what all
of us who regularly promote ARISS and AMSAT.
The first is from a gentleman who walked up to me before my presentation at
the ARRL Southwestern Convention in San Diego - to state that he was
attending the convention primarily to see my talk.

Hi Clint,
It was nice seeing you again at Hamcon on Saturday. I am glad to see that
you had such a great turnout for your informative presentation.
I have a success story to share with you. As you know, I bought an Arrow
antenna and duplexer at Hamcon and have been dying to get it on the air. I
assembled it the other night and checked for the next few available passes
(using the HamSat ap for my Droid X phone). On my commute home from work
yesterday evening, I detoured off the freeway and found the nearest, large
empty parking lot to try my luck with the next AO-51 pass at 1751 hrs (a 13
minute long, 37 deg pass). I worked one California ham, but cannot honestly
call that a completed QSO as I am not entirely certain of his call sign due
to the loud traffic noise I had to contend with from a busy highway
(probably not the best choice of locations for my first attempt). I did hear
him tell me that I was ?making it just fine,? so that was very encouraging.
My next contact was with a station in Edmonton (Alberta), Canada. That
contact I can confidently call my FIRST two-way Oscar contact! Wow, it
really can be done using a !
5 watt HT and a Tinker Toy looking antenna. I am very excited! Now I get
start work my way up the learning curve where it comes to better antenna
manipulation, better use of the pre-programmed channel steps in my radio
(following your suggestions), and learning the tricks that will enhance my
future success. Needless to say, I was a very happy camper after work
yesterday!
Thanks for reminding me that there is always something new and fun to do in
ham radio!

And THAT is why I do what I do. My accountant thinks I am nuts to travel
hundreds of miles and spend hours of prep time to make a one-hour
presentation (but she's not a ham ... I am working on her, though).
The second email today is an excerpt from the October, 2010 edition of the
Palm Springs' club Desert RATS' (WD6RAT) newsletter. I have presented out
there a couple of times, and they have been supporting the ARRL since 1998
as an Affiliate Member. From the "President's Message" this issue ...
- - - - - - - - - - - - - - - - - - -
... I attended a few workshops (at the ARRL SW Division Convention in San
Diego) ... and was also pleased to see a number of our members attend.
Notably, one of our members giving a presentation there as well ... Clint
Bradford K6LCS, our ?Satellite Guy?, was there giving his presentation on
handheld satellite contacts and representing AMSAT. He?ll be there at Palm
Springs Hamfest 2011 again too. His live demonstration alone is worth the
trip ...
- - - - - - - - - - - - - - - - - - -
SO ... although I feel guilty for not being directly involved in an
ARISS/AMSAT contact with the ISS, we measly "AMSAT area coordinators" are
making a "mark" on individuals and groups as we make our presentations and
demonstrations in our respective regions.

Gawd, am I embarrassed. I know three people named "Dee." Two of them I
interact with here in CA, and speak with occasionally. But I have never
(obviously) spoken with our "AMSAT Dee." I apologize for the gender error
misidentifying N2BF last night.
Geeze ... we have been interacting for years via email messages. A case of
how the 'Net can make one anonymous, I guess ... That, and my ASSumption ...
