Launched from Huntsville, AL on Friday, a 36" Mylar party balloon carrying
an APRS transmitter (WB8ELK-3) is now about 300 miles east of Florida and
managed one digipeater hit from that position this morning. If anyone in
eastern Florida can point a gain antenna east they might be able to copy the
APRS packets which I also transmit on 144.340 MHz once a minute. It is
currently 300 miles east of Melbourne FL slowly heading south towards the
eastern Bahamas. It is solar-powered only so will only operate during the
day today.

The ao73 has problems.
First of all the uplink could be as much as 5-10 kHz off from the published
numbers.so send a series of dits from your cw key while you sweep around
with ur uplink vfo to find yourself.
Once you find yourself, you have to adjust your uplink frequency about 200
hz per 30 min to keep up a drifting oscillator on the bird while monitoring
your downlink.once u get the hang of it,
It's not so bas.its a very very good with a great receiver ! P.S IT'S ONLY
AVAILABLE
AFTER DARK ON WEEK DAYS AND ALL WEEKEND FOR AMATEUR USE.

An International Space Station school contact has been planned with
participants at Dearborn Public Schools, Dearborn, Michigan on 27 Oct. The
event is scheduled to begin at approximately 16:01 UTC. It is recommended
that you start listening approximately 10 minutes before this time.The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between NA1SS and K8UTT. The contact should be
audible the eastern U.S, and adjacent areas. Interested parties are invited
to listen in on the 145.80 MHz downlink. The contact is expected to be
conducted in English.
School Story not available at this time
Participants will ask as many of the following questions as time allows:
1. How do you brush your teeth?
2. What do you do if you get ill or hurt?
3. What is the official language on board the International Space Station?
4. How would you describe the feeling of being in space?
5. What do you eat in space?
6. Do you see the earth, sun, and moon rotate?
7. What was it like when the Super Moon Lunar Eclipse came into your view?
8. What is your most recent, successful experiment you have done at the
International Space Station?
9. How do you sleep when there's no gravity holding you to a bed?
10. How do you stay fit in space?
11. When you were about to take off, how did you feel?
12. Do you have any side effects when you return to earth?
13. How do astronauts cope with the psychological stress of being away from
their families and friends for a long time?
14. How does our digestive system work in space with no gravity? How does
the food go down the throat and stomach?
15. How long can an astronaut stay in space before having to come back to
earth?
16. Is there a way that the space rocket ships could reduce the amount of
energy they use?
17. How does not having a normal day/night cycle affect your sleeping and
waking hours?
18. Why do you lose bone mass when you come from space?
19. Because of the fact that up in space there is zero gravity, how does it
feel when you come down from space and back to earth?
20. if there was something you could change about your space environment,
what would it be?

I have found that computer tuning for AO-73 simply doesn't work... the
satellite frequency drifts enough that your up- and downlinks won't stay in
sync for long. I leave my downlink frequency alone as much as possible
(unless needed to chase the other guy), and manually adjust the uplink, and
that has worked well for me.

I have been keeping a record of telemetry frames received (as per the total
shown in bottom right of software vs totals appearing in AMSAT Fox
Leaderboard Statistics.
My findings are shown below which show some large differences.
I have tried to understand where/why/how etc but can't find much to read
about the subject.
I am wondering if the server is not receiving all the packets then are the
experiments affected by this?
Can anyone explain why there are differences and what it means? According to
the software zero frames are queued so I am puzzled.
Has anyone else noticed this or am I the only person documenting this.
The table is below (I hope it comes out OK on the BB, if not please PM me
and I'll forward to whoever would like it to review)

AO-85 passes sounded good over the east coast this weekend. However, I set
up for the 04:06 pass and only heard what sounded like the satellite back
in test mode (female voice announcing this is Fox-1).
What is the status for this week, as there is a very good overhead pass
today at 20:06 UTC?
On a side note, I like others I believe, have found that getting into AO-85
with your HT and handheld Arrow or Elk antenna to be almost impossible.
Last evening I set up the Icom and used 20 watts, that was the first time I
actually made more than one contact.

Loon,
If you hear "Hi This is Amateur Radio Satellite Fox-1", the satellite
is in transponder mode. A transmission with the 67 Hz tone should
activate it.
The satellite is open for use for now, but there is likely to be
another round of testing later this week.

Hi George,
You are one of many who have said manual tuning is best, and after so many
similar comments, I should probably give that a whirl.
Of course this will vary for rig and doppler, but I'd be curious to know
what you find your tx frequency to be at mid pass?
The reason for asking is the published spec is
Uplink 435.150 - 435.130 MHz LSB (Inverting)
Downlink 145.950 - 145.970 MHz USB
Implying that a RX of 145.960 (mid band) would have a TX of 435.140. From
my tests it appears that I would actually have to transmit on 435.156 to
hear myself at mid-pass. That, of course, appears to be outside of the
published passband, and those published specs probably prevent anyone new
to the bird from ever finding themselves.
I appreciate and data or feedback.

(Thank you, Fox designers, for not requiring a different tone every 10
minutes like SO-50!)
That turns out to be a good barometer from my QTH for how high up the sat
has to get before someone can successfully activate it. When it comes up
from the south over the Pacific, it might get up to 20? elevation before
someone starts calling CQ. I know
for certain that my 5-watt HT and I are not triggering it before then.

Hi Bob.
AO-73 is difficult to track using a PC as there is a fixed offset on the
receive crystal oscillator together with a variation in frequency which is
temperature dependent.
Consequently, the ideal midband frequency when the satellite is at TCA will
be different for a pass in eclipse or a pass during the illuminated part of
the orbit.
As you know, it takes a bit of getting use to, but once you get the feel for
it, manual tuning can get good results.
I agree the published frequencies should probably include the fixed offset
so people can get a little closer to the 'correct' frequencies for success.

Hi David,
You are spot on, fortunately, this old dog used to manual tune all the
time, so its just a matter of me going back to my original ways to doing
things.
Knowing that the the LO is changing around a bit with temp makes me
understand why the Doppler corrections never seemed to fit what I was
hearing from the bird itself, even thought most of my operation is during
Eclipse (before it emerges back into light, when the temp should be cold
and fairly stable).
AO-73 is a great bird, and a pleasure to work, but I do hear people time
and again saying they can never hear themselves on the downlink. All it
would take is a published hint to try transmitting higher by about 8-12 KHz
for example, and I think folks would have much more luck. The information
is out there, in various forum posts, personal blogs, and message systems,
it just hasn't been adopted by authoritative sources like funcube.org.uk,
or AMSAT itself (which list the original ideal UL/DL relationships). Until
then it is sort of unconfirmed rumor.
Thanks again!

The 10m band was exceptionally quiet ( S-2 noise), this morning during
the 15:39u pass.
As a result, PSK-31 copy thru NO-84 was "As Advertised". The copy was
almost flawless except for a very few errors due to fade from satellite
rotation. Too bad no one else was around.

Over FN10 at 85 degrees. Heard N0JY and a "2" station but couldn't make out
the call. For a high pass it was very noisy and I found it difficult to get
into, even at 20 watts. I think I'd rather have a 30-45 degree pass.
