Ed,
Not sure what your setup is, but be sure your bandwidth is 11-12k for
High Speed. If you run the FCDP+ direct from FoxTelem then that is
taken care of, if you use SDR# or HDSDR or other software then you may
have it set (or it may default) to a narrower filter in NFM mode.

There is a lot of confusion about the random ISS contact by the UK
ham. In a video from when the news went viral last year, he said he
contacted them in October of the previous year. [1] So that would be
2014.
Currently the best opportunity for a contact is during SSTV events in
between the SSTV transmissions.
Not sure about "operation," but the ISS crew sleeps on GMT time.
That's a common question from students during ARISS contacts, and the
astronauts/cosmonauts always say GMT.

Hi Jerry
I was running HDSDR with 12kHz bandwidth. The BW appeared to cover all of
the parallel signal tracks. I will try FCD P+ by itself; I know that worked
last time (months ago) I tried it.
Thanks!

Alan,
A few days ago the satellite switched from DUV to HS shortly before my
LOS. The program was set to "auto" and I was able to decode and
uploaded my first six frames of HS data. Using V:1.03-h, the s/w
worked as expected..
Bob Vislay

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

I run about 15KHz wide. The SNR needs to be 7db or so on the telemetry
program before it decodes.

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.

I don't have the URL handy, but ISTR that the astronauts' daily schedules

also, the best time for the astronauts to make contacts is just before they

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.

They have round tubes, square tubes, solid round rod, in many (nesting)
sizes. I have used them and their quality is excellent. The only negative
I've experienced with dealing with them, and it is not really their fault,
is the surcharge that UPS charges for 8 foot lengths. If your project can
be handed with 4 foot pieces, your shipping charge will be much lower. If
you need some big (8 foot) pieces, it is worthwhile checking to see if any
hams in your area could also use some fiberglass, because the extra pieces
cost nothing extra to ship, due to the surcharge by UPS for long packages
which ship at the 60 pound rate if I recall correctly.
I have no ties to this company other than being a satisfied customer for
many years.

John,
These are two separate satellites. FUNcube-1, known on orbit as AO-73,
carries a linear transponder and a telemetry beacon for schools.
During the week, AO-73 normally operates in "educational mode" which
is a 300 mW telemetry signal while the satellite is in sunlight and a
30 mW telemetry signal along with a 20 kHz wide linear transponder
when the satellite is in eclipse. On weekends, the command stations
put it into transponder mode full time since schools are generally not
open, so a strong telemetry beacon for educational purposes is not
necessary.
EO-79, the on-orbit designation of QB50p1, is a satellite that is
designed to test payloads for the QB50 project, which involves a fleet
of 50 cubesats being sent to a very low orbit in order to study the
upper atmosphere. It carries the same style transponder as AO-73. The
transponder is known as FUNcube-3. That transponder has now been
activated for amateur use following the conclusion of the scientific
mission. Unfortunately, the satellite's power system is not sufficient
to power the transponder for a long period (it has a negative power
budget), so the transponder shuts off and the satellite switches to
safe mode when the battery voltage falls beyond a set voltage.
And yes, there is also a FUNcube-2. It's on board UKube-1, an
experimental satellite built by the UK Space Agency. The telemetry
beacon (similar to AO-73's) has been active since the end of the
satellite's primary mission, but there has been no further word of
transponder activation.

Paul, N8HM
