First of all, let me apologize for any disruption I may have caused by my
tests (experiment, interference, ...).
Last evening around 0120Z I was indeed transmitting MSK144 on a downlink
frequency of 435.878 (at the satellite) on a pass of FO-29 with a 4 degree
max elevation at my location with the satellite over the Atlantic. The pass
was monitored by a station in Virginia as a test of using MSK144 at low
angles. I deliberately transmitted near the upper end of the passband. I
continuously monitored the passband on my panadapter and there were quite a
few QSOs on that pass, all well below my frequency.
I also did a test around 0300Z as shown in your link
(http://druidnetworks.com/w5rkn-msk144-fo29.jpg)
If I interfered with any of those QSOs, I am sorry. The test confirmed that
MSK144 could be decoded at weak signal levels even in the face of Doppler
shift.
As far as the AO-7 incident you mention below, I did on a couple occasions
inadvertently cause a mode switch. I was certainly not the only station to
cause this action. Because I knew how that action could accidently be
caused, I did make a couple posts to AMSAT-BB to help others avoid this
mistake.
Again, I am sorry for any problems this may have caused.

FO-29
On the FO29 pass at 0155z this evening, I noticed a very hard time getting
into the transponder. The pass was nearly overhead, and the 3w-4w that is
normally sufficient was barely cutting it. I also noticed it was 'up and
down' alot, whereas some moments it was easy to get in, then it would be
nearly impossible. There were also pockets of 'noise' all over the
transponder, that sounded somewhat digital, but I just couldn't place them.
I found W5PFG in the passband (who was portable in a rare grid in western
Texas) and he commented on the difficulty of working an otherwise easier
bird tonight as well. I checked the screen, and no other birds were
obviously in range, so I started scanning around the passband to see what I
could hear. Up around 435.870 I found (or rather heard) what I was looking
for. I fired up my recorder and captured this:
https://drive.google.com/open?id=0B8W_KstbAsD_VF9NbGR3ZXlicUE
For those not familiar, that is the telltale sound of MSK144. I work a fair
amount of Meteor Scatter in addition to operating satellites, and the noise
is unmistakable. Since my shack PC has wsjt-x installed, I quickly fired it
up and went to the msk144 mode and after some quick tweaking started
decoding the signal. This is a screenshot of what I saw:
http://druidnetworks.com/w5rkn-msk144-fo29.jpg
This signal continued for at least 8 minutes (that I recorded) in a 5 second
T/R cycle while FO29 was passing high over North America. Every 5 second the
digital signal would get transmitted, and all other SSB qsos would start to
fail. You might call this an experiment, but I call it intentional QRM.
*For the record* You are not the first person to play with wsjt-x modes on
the linear satellites. Some months ago during the late night hours on the
XW's and FO29 when the footprint was primarily over the desert southwest and
south pacific, I to "experimented" with FT8 and MSK144. I purposely ran my
transmitted signal thru over 100ft of low grade coax to attenuate my uplink
to ~1.5w ERP. I made sure the entire transponder was empty before starting,
announcing myself, then started the transmission. I decoded myself
successfully, said "Well that was dumb" and never did it again. I purposely
didn't announce what I had done to the world because I knew someone would
think they were being cool too, and would fire up a 2700hz wide 50% duty
cycle mode on a high US pass and QRM people trying to make QSOs out of
existence, because said individual would lack even basic situational
awareness and courtesy to others. What is extra hilarious about the fact
that it is you being the responsible party
for destroying a pass, is your constant whining to this mailing list about
people using too much power on AO-7, when you're one of the worst offenders.
On July 16th this summer, I was roving in EM35 and you called me on the
2155z pass of AO7, and you got the first 3 letters of your callsign out
before you killed the bird. I know it was you, because I had already made 3
QSOs right at my AOS with other stations using a reasonable amount of power,
and as soon as you key'd up the whole bird started FMing and croaked before
you even finished your call. You didn't get that grid that day, and after
the stunt you pulled this evening - you won't be getting any grids from me
in the future either.

To all,
Isn't our mission one of experimentation? What, exactly, is wrong with
utilizing, with the proper power and bandwidth limitations, part of a
transponder passband for non-SSB/CW modulation?
Yes, there are considerations regarding AO-7, but that is a problem we
face using any mode on that satellite. CW signals routinely modulate the
SSB voice signals, unless operators take care to restrict uplink ERP to
the minimum necessary for a QSO.
Modes like Olivia, which has FEC and can track frequency changes
(Doppler or otherwise), should be easily workable over satellite, and
may not need to be much above the noise floor.
Ron may have been running a bit too much uplink ERP, but I don't think
he needs to be beaten over the head for doing what Amateur Radio is all
about: experimentation.

Experimentation isn?t the problem, too much power is. It?s bad enough on
SSB, worse with CW, and killer on constant duty cycle modes like FT8.
I?m one of the few newer sat guys I think that actually likes CW on
sats....BUT, I know that more than a couple watts of CW into my Arrow can
kill the transponder for everyone else. With digi, the effect is far worse.
It?s already bad enough when I can tell that certain SSB stations have come
on somewhere else in the passband, because my signal, which moments before
was very loud using 500mW of uplink power, completely disappears even though
I bump up the power to 5 or 10w.
I personally don?t see the point of a mode like MSK144 on sats, which is
designed for extremely weak signal contacts like meteor scatter. But, if
somebody wants to experiment that?s cool. Just keep the power down - WAY
down, and I don?t think anyone would say a word about it. But no matter the
mode, If one station is shutting out all others in the passband, well,
you?re probably going to see some ranting lol.

Hi Andrew,
Just use the FUNcube Dashboard...the Dongle is designed for it and nothing
else, in terms of hardware or software, is needed (except the antenna of
course).. all details and the helpful user manual are here

An International Space Station school contact has been planned with
participants at Tallaght Community School, Dublin, Ireland and
Raddningsgymnasiet Sando, Minerva School and the NTI Gymnasium Sundsvall on
Oct 19. The event is scheduled to begin at approximately 12:49 UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between OR4ISS and EI2SDR at Tallaght Community
School, Dublin, Ireland and telebridge via EI2SDR and the
Gymnasium R?ddningsgymnasiet Sando, Sand?verken, Sweden. The contact should
be audible over portions of Ireland and adjacent areas. Interested parties
are invited to listen in on the 145.80 MHz downlink. The contact is expected
to be conducted in English. Watch for live stream from Tallaght Community
School:

https://www.youtube.com/channel/UCdW96C_lHQx81qCSbW-Jzbw
and https://go.twitch.tv/ntigsundsvall (***)
Tallaght Community School is located in Dublin city in Ireland. The school
was chosen for the event as it is in a disadvantaged area and the school
works hard to prepare and encourage students to pursue some form of further
education. The school has 900 students aged 12 to 18 years and all will take
part in the event.
All students have studied about the ISS and were given an opportunity to
submit questions to be selected.
Sand? is located about 400 Km to the North of Stockholm. The participating
schools are R?ddningsgymnasiet Sand?, Minerva school ?nge and the NTI
Gymnasium Sundsvall. Together they count 550 students ranging from ages 12
to 19. Sand? R?ddningsgymnasium is close to nature and overlooks a beautiful
fjord. Besides teaching science programs, the gymnasium offers courses in
civil crisis management, firefighting as well as search and rescue. Students
are prepared for a career as teachers, nurses, psychologist, firemen, fire
engineers and policemen. Together with the Folke Bernadotte academy as well
as other governmental organisations, they create an understanding of and a
preparedness for international assignments. Part of the education is that
the students travel around the world to learn from existing fire and rescue
situations. Amateur Radio is also included in the student's graduate projects.
The NTI Gymnasium Sundsvall or the Northern Technical institute, established
1968 offers courses in digital techniques, internet technology and other
forms of digital communication. The institute has about 250 students.
Minerva school ?nge teaches younger students from age 12 to 15 and has of
about 200 students enrolled.
Participants will ask as many of the following questions as time allows:
1. What is your favourite view from the ISS?
2. Do you ever think children will be allowed to travel into space with
astronauts?
3. If you had the chance would you change or add anything to the design of
the ISS?
4. Is this job the most challenging job you have ever done?
5. What is the longest time you have spent on a spacewalk and what did you
do?
6. Does the ISS have a black box like an aircraft?
7. Who inspired you to become an astronaut?
8. Have space experiments resulted in something useful which is used on
earth?
9. What training did you do to prepare for space walks?
10. Have you ever encountered an anomaly that has baffled you?
11. This is your third trip to space, did it take your body more time to
adjust to earth's gravity the second time you landed?
12. What education in physics and engineering is required to become an
astronaut?
13. When your mission is over what will you miss the most and least about
life on the ISS?
14. Does your view of life change after seeing earth from another
perspective?
15. Can you tell us about some of the interesting experiments you are
conducting on the ISS?
16. Are you allowed to bring along private things like photos?
17. Is the ISS ever affected by solar radiation surges from the sun?
18. Do you use "private" communication channels when talking with your
family?
19. Have you had any fun or exhilarating experiences so far on your mission?
20. How does it feel to see earth from such a distance for the first time?

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 informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.

All:
Need advice from the reflectors TNC Guru. I have a Timewave PK-96 in the
shack and would like to test the modems receive capability by monitoring
9600 baud satellites.
I figured it should be possible to monitor incoming packets with a
simple terminal program, but after trying Tigersat and others, I was not
able to decode anything. The same radio worked fine with UZ7HO's
Soundmodem.
I used the terminal program to set the TNC in 9600 bd mode and set the
mon command to monitor UI frames. Maybe I'm missing something.

The transponders on these satellites were turned on last night. They sound
much like the XW-Xx birds--good ears and strong
downlinks.
Two more opportunities now available.

Worked N4IQV on 4A, nice strong downlink and very easy to get into with my
817s. It might have been a problem on my end but the uplink freq seemed to
be lower than I was expecting, it took me a few seconds of tuning around to
find my downlink signal.

Worked KB6LTY on both CAS-4A and CAS-4B this morning with very strong
signals even though I only had a 1 degree max elevation pass on CAS-4b and
a max elevation of 4 degrees on CAS-4A. Signals were extremely loud and
Christy KB6LTY also had very low elevation passes. Thanks to Glenn AA5PK for
the heads up.. DE JACK KC7MG
