We had a nice QSO few minutes ago on a high pass over here , PY5LF, PY2RN ,
PU2RAS , very good signal .
I'm using 13kHz above on the uplink to match ;

Hi Ed,
That is what HS looks like. There have been 2-3 other periods of HS
telemetry over the past few days.
In the ones I saw or heard, my software did not automatically switch, and
when manually switched
copied nothing. There are known issues with HS in my station which I am
working on, so that is not
entirely unexpected. I was able to copy a few blocks on a much earlier
test. From other comments,
you do need a stronger signal than DUV, and depending on your equipment, a
higher sampling rate.
73s,
Alan

Just worked the 16:15 UTC overhead Pass of EO-79, Working 3 Stations N8HM
NS3L W5PFG down to AOS. The bird faded alot so alot of polarity switching
was required on the downlink and uplink but signal strength wise it sounds
like AO-73. Was a rush working that pass, alot of stations were on!

16:15 UTC EO-79 pass over Texas, USA (grid: EM21)
- 7 stations worked including 1 DX, a few others heard
- Had to change RX polarity a little more often than TX polarity;
overall very easy to hear like AO-73
- Very little uplink power is necessary as with AO-73
- Could easily work the entire transponder from end-to-end of pass band
Many thanks for activating the transponder and for making it available
to the amateur radio community!

Do any of the "hams" in orbit just like to play radio in their spare time?
You know that "drive" to work WAS, VUCC, DXCC. etc. Obviously they would be
classified as a "rover". The school contacts are a good demonstration for
the non ham public. Then there's the rest of us. They all have at least tech
license, but appear not to be "real hams". Shields up.

Bob,
Unfortunately for us (but fortunately for them), they have far more to
do in their spare time than they did back when a few of them got on
the radio and worked towards WAS and DXCC from orbit! They have
laptops with full internet access now and can videochat with their
families or just waste time online like we all do.
All we can hope is that we'll get someone up there that's interested
in using the radio in their spare time again.

Paul, N8HM

This method works well and many of us making VHF Quads/Quagis have been
doing this since the 80's. But why go to the expense of Fiberglass tubes -
we use thick wall UV-PVC with a wooden down inside to stiffen giving it much
strength.
I use PVC w/wood for the Quad boom and vehicle Mast for "T" hunting. Trust
me, high vehicle speeds and low tree limb grabbers we find during a southern
California T-Hunt is very stressful to any vehicle antenna/mast above the
hole in our vehicle roof. Some of us use Gorilla-Glue as a filler between
the dowel and PVC (as Gorilla-glue expands making a solid fit).
I use 1.25" PVC sched-80 w/wood for my SAT antenna cross-member boom -
keeping it non-conduction/metal free to insure no skewing of the directional
lobes within the field pattern. ?

Another trick for strengthening fiberglass tubing is to get wood round stock
at Lowes or Home Depot that
will just fit inside the tubing.? Years ago I found something which was a
perfect friction fit, though
obviously it depends on the tubing.? Cut the wood about 2" shorter than the
tubing, and center it
leaving a 1" space at each end.? I stood the tubing on end, and filled the
top with RTV.? After it
hardened, I reversed the tubing and repeated the process.? The result was
lighter than a solid
fiberglass rod, waterproof, and lasted for 15 years until the whole thing
came down in a windstorm.

It does happen:

ks-to-space-station-from-garden-shed.html
This is from just last year.
The trick is to figure out their break time, and match that with the
time they are passing over your location. The radio is normally on low
in the Russian module. If you call, and they are on a break, and they
happen to have the radio in the correct mode to hear the uplink, then
they might say hello back. The next technique after a response is to
not panic!
The European module radio is on APRS duty normally.

also, the best time for the astronauts to make contacts is just before
they are ready to go to bed. that is when they have some free time. keep
in mind that the iss operates on russian time (i think same as moscow
time). breaks might be harder to determine but beddy-by time is almost
always the same.

Hi Alan
Thanks for the note. I, too, have successfully received high speed telemetry
in the past, although it has been a while. Wonder what changed. Maybe Drew

Hi All,
FC1 is now in continuous transponder mode for the holiday period. Normal
autonomous operation will recommence from late MONDAY evening.
As reported earlier today, the transponder payload on EO-79 has also been
switched on and, so long as the on board bus voltage stays up above its safe
mode setting, then this should also be active.
Have a great FUN weekend and enjoy the birds.
