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
digi contact:

Wallers, Saint-Amand-les-Eaux (59), France
Message-ID: <05EA2488E6F4432E8B62AE17EC4558EA@xxx>

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) L?once
Mal?cot (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 d?cid? de devenir astronaute?
2. Quels sont les qualit?s qui ont ?t? d?terminantes pour ?tre s?lectionn?
pour cette mission?

About ARISS:
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,

Try listening to a pass first. If you can hear 'em, you can probably work
'em. I used a Yaesu VX-6R for my first year of operating SO-50. My
Baofeng BF-F8 is deaf on receiving the FM sats, but it can be used to
transmit, if I use the VX-6R to receive. Your mileage may vary.

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 !

Devin,
I use the Baofeng UV5R and a Wouxon for the FM sats. Both radios work
excellent and are so portable along with my arrow antenna. For receive and
having to adjust the receive frequency, I prefer the Wouxon only because it
has a knob on top of the radio to tune the freq. I use the Baofeng to
transmit and the Wouxon to receive. I prefer full duplex.
Good luck,
chad

Since the Tracker is internally serial, there is no avoiding a
USB-Serial adapter. Either you can use one externally, or try to build
it inside, but that circuit will be there either way. Just make sure
you get one with an authentic USB chip in it, not one of the counterfeit
ones. You'll be forever fighting driver issues otherwise.

Is anyone else having problems getting telemetry out of AO-85? I just
had an 83 degree pass and got zero data packets decoded. I saw the
satellite signal on the "waterfall" and it was pretty weak.
This summer I would get 30 to 40 decoded data packets out of a high pass
like that. Is it me or the satellite?

David,
On the LVB PC board, beside the serial port, is a socket which will take a
USB chip complete with
connector. You remove the serial port chip, and install the USB chip.
As for the USB chip, the old part number was DLP-USB232M, which has been
replaced by the
626-DLP-USB232M-G. Mouser has them at $25.
AMSAT used to sell them, but there were some reports that the computer would
lose connection with the
LVB, and so the use of an external adapter is recommended. That is usually
the cheapest way to go.
73s,
Alan

Subject: [amsat-bb] Channel settings to work BY70-1
Message-ID: <89a35d81-1085-8e67-2a0a-bf5ba59c863e@xxx.xxx>

Greetings,
I'm looking at setting up my hand-held radios to attempt to
work BY70-1. Given that my radios have a minimum step size
of 2.5 KHz, I'm trying to set them up to account for the
frequency sensitivity of BY70-1. I am going to use the
channel set listed as follows:
CH RX TX TX Tone
BY70-1 436.2100 145.9175 67 Hz
BY70-2 436.2075 145.9175 67 Hz
BY70-3 436.2050 145.9175 67 Hz
BY70-4 436.2025 145.9200 67 Hz
BY70-5 436.2000 145.9200 67 Hz
BY70-6 436.1975 145.9200 67 Hz
BY70-7 436.1950 145.9225 67 Hz
BY70-8 436.1925 145.9225 67 Hz
BY70-9 436.1900 145.9225 67 Hz
Does anyone see anything errant is this plan, such as a shift
in the base TX or RX frequencies? If so, please let me know.
Otherwise, I hope that this channel set may be useful to
others.
73,
Mac / AE5PH

If you are still using yesterday's TLE set, then you will indeed find
that BY70-1 is now about half a minute earlier. The problem is that
the TLEs for this satellite are not stable yet in the first days after the
launch. The right value for e.g. the decay rate has not yet been
established. So for the time being you need to make sure you use the
most recent TLE set that is available.
By the way, the two SuperView satellites are now using their own
propulsion system to increase their altitude, preventing an early decay.
As BY70-1 does not have any propulsion, it is stuck in its low orbit.
