Has anyone used a Yaesu G-450A azimuth rotator with an AMSAT LVB Tracker Box
and SatPC32 for computer control of azimuth only aiming for your satellite
antenna system?
Thanks,

Hi,
For a small club satellite presentation I will be mentioning the
benefits of HEO over LEO and the range advantage.
Can anyone tell me the distance record set when AO-40 was alive?
Thanks

Hello Pete
I'm sure you will get lots of answers. But my own personal favourite
response to a CQ call on AO-40 from London UK was a Japanese station located
at
one of the south pole research stations.
London to Perth Australia on AO-13 is also in my log, but it was impossible
to get from here in the UK to ZL.
My local club also took equipment to ZC4 in Cyprus and C56 (Gambia) making
about 200 QSOs from each location. DX-Peditioning was popular on the HEO
sats.
Happy days...........
Good luck with the talk

Pete and all...
The one I used to like to tell--
I am almost always at a hamfest sitting next to the DX association Rep.
I ask how far he has communicated? He says- halfway around the world about
7-8000 miles...I then
Tell him I talked from Lodi, NJ to Fairlawn, NJ (About 5 airmiles away) -
he looks at me strange and then I
Explain that I used AO-13 that was 30,000 miles up and 30,000 miles down so
I did beat any distance he had on the Earth..Hi, Hi.
HEO was fun and we still cry for another bird, however, we are dealt with
the hand we have...
Just show the "footprint" of an HEO vs. LEO and you will have a great idea
of distances involved.
Good luck with your presentation and don't forget to bring info about
joining AMSAT.
73,
Dee, NB2F

Hi Pete,
I'm sending you a couple of links of more possible ham operating
possibilities a HEO could provide ... in addition to the nice DX we enjoyed.
A few years ago when another HEO seemed feasible I let my imagination go to
work and wrote a couple of "proposals" for amateur radio missions ...
1. Use HEO for communication links in large-scale Incident Command Systems.
I wrote a symposium paper for 2008 on this topic and CQ VHF Magazine also
published it:
http://home.comcast.net/~k9jkm/CQVHF_Eagle_ACP_Emcomm.pdf
2. Use HEO to expand ARISS School Contact time from 10 minutes to whole
orbit coverage (AMSAT Symposium 2009):
http://home.comcast.net/~k9jkm/Education_AMSAT_Eagle.pdf
(Note both of these were strawman proposals that haven't gone anywhere until
flying high becomes a viable option again. Had AO-40 survived we could have
started on these projects as well.)
Perhaps this will give an additional talking point or two in addition to the
DX. Good luck with the talk!

Another interesting situation involving AO-40 (sobsob) was when running full
duplex there was a very noticeable delay while monitoring yourself.?
Figuring the round trip distance and the speed of light.? I had to turn down
the volume a little as I started talking sort of strange.? Damn- there's got
to be a way, maybe pool all our Visa cards, if I win the lottery I'll buy a
launch.? There are a lot of very smart and "connected" people in the various
AMSAT organizations around the world.? A HEO does not have to have every
bell and whistle we?can think of.? Keep it simple stupid (kiss).? Our DL
friends seem to have the best (only) design.? I spent some time looking over
my old AO-40 QSL cards (sobsob).? Someone mentioned they took some equipment
for DX-peditions.? A HEO provides an very reliable platform for emergency
coms.? I could go on and on, but I'm preaching to the choir.? I still have
my L & S equipment functioning.? I'll remove it when they pry it from cold
dead hands.?

Hi Pete, 2i0VAX
My DX record on AO40 from JN70ES Naples Italy was a QSO with
ZL2AOX Ian Ashley in RF72MV with a distance of 18299.0 Km as you
can see in the following page of QRZ.com
http://www.qrz.com/db/ZL1AOX
The uplink was in L band and the downlink in S band
This is why it is very important to pull for the new HEO satellite P3-E ! !

Greetings to all,I may have what should be one of the most "footprint
stretching" DX QSOs via AO-40. A group of German fellows made a DX-pedition
to Cocos (Keeling) Islands in 2003. Their grid locator was NH87 and my grid
was DN81. I heard them only once and it was on a day near the end of their
operation. I was hearing a few fellows on the West Coast working them but I
couldn't hear a "peep" from the DX station. All of the sudden they were
there, Q5. I couldn't believe my ears! We exchanged the usual 5NN on CW as
with most all expedition signal reports. My Elmer, Joe, K0VTY, and I had
often talked of stretching the footprint but it never occured to me that I'd
have the opportunity to do just that. As I recall, there were less than 5
degrees, according to InstaTrack, for me to make the contact before LOS at
both ends. I always blamed the giant Elm tree just accross the street from
me for preventing my hearing much that appeared on the low western horizon.
After I!
collected my senses, I went outside and had a look at that "cursed" tree.
To my suprise my antennas were pointed at a "hole" in that tree no bigger
than a bushel basket. Obviously that hole provided me the one in a thousand
shot I had at working VK9CD on the 20th of Oct., 2003. I have been a DXer
for over 50 years and I've had many memorable and lucky DX QSOs but VK9CD
ranks right up there near the top of my list. I wish that we still had a
bird in orbit that would allow such "thrills" but alas.......73 to everyone
and we can continue to hope.... Frank, K0BLT
