I first got on the sats back on AO-13. Seem to me back then when we operated linear satellites (FO-29, RS’s etc) we found ourselves on the receive passband and as the doppler changed we adjusted our transmit freq to make sure we stayed on the receive frequency.
Of course things have changed since then and many use some sort of satellite tracking software to control the doppler adjustments on the radio. But when you are operating portable what is the proper procedure on the linear sats?
Awesome FM satellite !!
Would have been THE replacement for AO51.
Really great signal, extremely sensitive.
Many EU stations QRV this evening.
Worked 2E0SQL, PE0SAT, EA1JM .... and did hear DK3WN !
TS2000, 2x6 elements for uplink, 67 Hz tone
TS2000, 16 elements for downlink
An International Space Station school contact has been planned with participants at Primary School Georges Wallers, Saint-Amand-les-Eaux (59), France on 31 Dec. The event is scheduled to begin at approximately 11:31 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between FX0ISS and F4KJV. The contact should be audible over France and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in French.
Saint-Amand-les-eaux is a city of approximately 16 000 inhabitants located in the north of France near Valenciennes. It is a spa town.
The students participating in this project come from two different schools: the 5th Grade class (CM2) at the Georges Wallers school and another 13 young people with disabilities from the Institut Medico-Educatif (IME) Léonce Malécot (aged 12 to 18 years).
The IME is a specialized institution that welcomes more than 100 young people, almost two thirds of whom have access to appropriate schooling.
The main interests of the ARISS project for these young people are to be open to the outside world, to invest in a project, to develop self-esteem and to take an interest in scientific culture.
Participants will ask as many of the following questions as time allows:
1. Comment avez-vous décidé de devenir astronaute?

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,

This was my second contact through the ISS digipeater. I actually
contacted the same station I contacted in this video, W8LR, three days
before, but I wasn't recording any video.
For this video I recorded the audio from my Kenwood TH-D72a and later
played it back to Soundmodem+UISS. Soundmodem decodes many more
packets than my radio does. I made a screen capture of UISS and its
map so you can see the complete details of every received packet.
Another thing this video shows is how hard it can be to track a near
overhead pass (close to 90 degrees elevation). When I was beginning in
satellites I only tried to work overhead passes because I knew the
signal would be strongest when the satellite was closest to me. While
that is true, the closer the satellite is to you the faster its
relative speed is. When it passes overhead it switches from coming
towards you to going away from you very fast, and drops 10s of degrees
in seconds. That makes the satellite very easy to lose track of.
In this video I got distracted while changing settings on my radio and
lost the ISS after it went overhead. It didn't help that I was using a
tripod for the first time. I prefer to hold the antenna in my hand
precisecly because I find it's easier to track, as I can make quick
adjustments and listen for the signal going up and down. To control
the radio for packet, it helps to have two hands. See my previous UHF
ISS digi video to see how hard it is to change settings with one hand.
Here is the very appropriate QSL card I got from W8LR for my first ISS
Thanks for watching,

I worked N8HM, AC0RA, AA5PK, and XE2AT on a 75° pass earlier this morning, using 5w from a D72A HT and an Arrow antenna. Because of the 5khz tuning steps on the HT, it was a little tough getting in except for a short window +/- about 1 minute before and after TCA due to uplink Doppler shift. I could key the transponder earlier/later in the pass, but my audio was pretty poor except during that brief window around TCA.
On the same pass I heard KI4RO work several stations, and also last evening W4FS, both who were using HTs and handheld antennas. So, it's definitely possible with low power from an HT. I'll be experimenting some more on upcoming passes to see just what is possible with basic equipment.

I have seen some messages about this satellite, but I havent seen mention
of 67Hz subtone.
I had signal at 18:30UTC over russia, as I switch on CTCSS. Unfortunately
none was with me on the pass.
But in case I'm not the only one who miss subtone, now its mentioned.
Audio was good, but has delay like Paul, N8HM mention at hes message.

The FM transponder was active on BY70-1 for the passes over North
America this morning. K4KDR reported hearing my call on the pass
around 1540 UTC, but I did not hear myself. On the 1709 UTC pass, I
worked AC0RA and heard AA5PK.
The signal is strong, but the uplink seems to require precise Doppler
tuning. I was only able to get in cleanly when tuning for Doppler,
starting at around 145.917 MHz near AOS and tuning up to 145.923 MHz
near LOS. An FM only radio with only 5 kHz steps may not work well for
accessing this transponder.
There was also a clear SDR delay on the downlink signal which makes
things interesting and it seems to require a bit of power to break the
squelch. I was using about 30 watts on this pass.
Equipment used was 2 FT-817s, a High Sierra Microwave preamp, a
Microset VUR-30 amplifier, and an Alaskan Arrow antenna with the top
section removed (8 elements on 70 cm and 3 elements on 2 m)
Unfortunately, the satellite's life is destined to be quite short due
to the incorrect orbital insertion with a very low perigee. The
2016-083A keps from CelesTrak's TLE-NEW.txt file seemed pretty
I have posted a recording of the pass. Skip ahead to about 2:35 of
