Contact is a go for: Sat 2017-06-10 16:18:48 UTC 88 deg (***)
Proposed questions generated by the Greater Niagara Frontier Council BSA
students:
1. What motivated you to pursue this career? Did you ever imagine being able
to go to the ISS?
2. What is the hardest thing about living on the space station?
3. Is there the possibility of expanding the ISS for a more fuel efficient
launch site for lunar or Martian missions?
4. What do you miss from Earth that you don't have in space?
5. What is the coolest weather pattern you've seen from the ISS?
6. Can you access the internet in Space? How are you connected?
7: Recently, an experiment in growing potatoes was launched to the space
station that was designed by students from the Buffalo area. Are you
familiar with the experiment? How is that experiment proceeding?
8. What experiment has been the most fun for you and why?
9. What was the most difficult challenge that you had to overcome to become
a cosmonaut?
10. Which area of STEM (Science, Technology, Engineering and Mathematics) do
you find most useful as a cosmonaut on the Space Station?
11. What are your daily meals like? (Are the meals from other nations
similar or different?) Do you get to trade meals with others?
12. What changes happened in your perspective of Earth when you went so far
away?
13. Scott Kelly was onboard the ISS for 340 days, what is the next increment
for time in space for Mars travel to be practical?
14. Many of the experiments done on the ISS are for scientists around the
world. Do crew members keep up with the research projects after the
specific experiments are done?
15. In February the ISS twitter feed had a photo of a lone ship on the
ocean. Have you ever felt like you were a like that lone ship as you work
in on the ISS?
16. Which of the experiments you are doing during your ISS mission do you
think will have an impact on my life?
17: I read that astronauts average about 6 hours of sleep a night, with a
goal or 8 hours. Why is it hard to sleep on the space station?
18. What pictures of the Earth have you taken, and what is your favorite?
19. What would you say to young students about a career in science,
technology, engineering, or math?
20. Were you ever involved in Scouting?

If you look at my screenshot you can see I was receiving on 1485.966+ 916 IF
downconverter=2401.97 MHz, consider than doppler shift and downconverter
error and you are around the nominal frequency of 2401.843 Mhz.?The others
screenshot with telemetry analysis where coming from cw beacon signal.
Mission is ended but you can find cw telemetry beacon decoder algorithm

Content-Type: text/plain; charset=us-ascii
I'm having a strange issue with my 821. Periodically I lose all sensitivity,
which I've particularly noticed on 2m SSB. I can attach and detach an
antenna with no change in the noise level, and can't hear anything in the
receiver (like the XW-2* beacons, or the AO-73 telemetry). Resetting the
radio seems to fix it.
It doesn't appear to be affecting 70cm, although I haven't had much chance
to test that (there's not always a mode j sat up at the same time as a mode
b one, and when it happens I'm normally just trying to reset the radio as
fast as I can do I can operate the pass). Has anyone experienced anything
like this before?

Content-Type: text/plain; charset=utf-8
Mode A has always been weaker than Mode B, but with a decent 10-meter
antenna it is quite usable. Many operators access Mode B with a 2-meter
beam of some sort, then try to hear Mode A with a dipole or ground-mounted
vertical , then complain that they cannot hear it.
There is no substitute for a good 10-meter beam. A tri-bander usually works
too, but check the tuning to see that the SWR isn't too high at 29.5 MHz.
If it is, you may have to re-tune it or even shorten the elements slightly.
If you absolutely cannot put up a beam, your second choice can be a 10-meter
ground plane, elevated so it is mounted in the clear. It has no forward
gain of course, but it will give you a low radiation angle, which will help
in hearing AO-7 when it is at low elevation which it is most of the time.
With Field Day coming up, a little attention now to your 10-meter antenna
will show up in your results later.

A good 10 meter antenna for the size and price is the MFJ 1890 2 element
Moxon Yagi. It costs less than $100, and the longest element is about 12
feet long, and easy to turn with a TV rotor. A couple of years ago I
worked 103 countries on 10 meters during the weekend of the CQWW contest,
and that was with the antenna at 16 feet high and blocked to the north by a
part of my house with steel siding on it. Probably not a worse place to put
an antenna, but it worked!

How does it compare now to back then signal strength wise?

on an az-el mount with a TV rotor for the elevation.

works too, but check the tuning to see that the SWR isn't too high at 29.5
MHz. If it is, you may have to re-tune it or even shorten the elements
slightly. If you absolutely cannot put up a beam, your second choice can be
a 10-meter ground plane, elevated so it is mounted in the clear. It has no
forward gain of course, but it will give you a low radiation angle, which
will help in hearing AO-7 when it is at low elevation which it is most of
the time.

I haven't tried AO-7 for quite a while. ?Therefore, I cannot give a real
comparison.
