On June 1st between the hours of 9:00AM and 3:00PM EDT the Chesapeake Center
For Science and Technology High School Amateur Radio Club
in Chesapeake, VA (FM16) will be holding demonstrations for area advanced
science teachers.
They will be operating FO-29 passes (13:11, 14:54 and 16:40 UTC) & possibly
other satellites during those hours as W4FOS .
Please give a listen and a call.
Thanks

Hello to all!
Tomorrow morning, I will support a Physics class at my University (UCF). We
will be using Doppler measurements on the HO-68 beacon to calculate
satellite velocity and from that result, we will calculate orbit altitude.
We know that there will be a potential source of error as we are not
stationary but anyway we hope to get a reasonable approximation of satellite
velocity and altitude.
We will be running the Fun Cube Dongle with SDR Console V2.0 and ELK
antenna. SDR Console allows remote network connection, so I will be tracking
the satellite from a tall building but students and teachers will be able to
see the experiment and collect data from the laboratory.
FO-29 will be in range just after the 1510z HO-68 pass. I will switch
frequencies and will try QRPp running just 3W to avoid desense in the
Dongle. If you hear me, please give me a shout with your name, city, state
etc. Students and teachers will be still listening.
I have made some Demos before for them, so they are familiarized with Ham
radio and satellites.
73!

Do not use silly overcomplicated radios and pointy-clicky software. Don't
waste time with directional aerials and Heath-Robinson rotators.
Grab some pass predictions, and stick a handie with a rubber duck in a
south-facing window set to 145.825MHz - if the ISS is transmitting you will
hear it.
The ISS isn't always in packet mode, and in particular they shut it off
during EVA and docking/launching procedures. If it's up and talking (check
issfanclub for details) you *will* hear it.

Many of you may have read about the successful QSO between DJ5AR and
Jan, PA3FXB using the ISS as a
passive reflector, similar to airplane scatter or EME.
Using EME protocols and periods of 30 seconds, they completed the QSO
using CW. This involved modifying
satellite tracking software, and compensating for the Doppler shift. You
can read details and hear audio files on
DJ5AR's blog here:
http://www.dj5ar.de/?p=878
This is quite an accomplishment, but I instantly began to wonder if it
couldn't also be pulled off with much simpler
equipment using WSJT software such as FSK441 (commonly used for rapidly
moving meteor scatter QSO's).
Doppler shift would not be a problem, even with the quick moving ISS,
since the software is already optimized for
short transmission periods.
It might be necessary to modify the standard messaging to allow for a
complete QSO exchange to happen faster,
or to shorten the periods to 15 seconds.
432 MHz has already proven to be very productive for airplane scatter,
so I also wondered if 432 might be a good
band for this type of experimentation. Lots of satellite operators are
already equipped to operate on 432 and to track
the ISS in real time with their antennas.
I'd love to hear some discussion about the possibility of this. It could
open up a lot of potential grid squares on 432 and 1296
simply using FSK441.
Another problem to be solved is classifying the propagation mode in LoTW
and other logging software. Would this be considered "airplane scatter"
or would we have to invent a whole new name for this?
Congratulations to both hams for this accomplishment!

If You use UISS software for packet , You can click on the " help " option
in the top menu line and then click on stations heard via IGATE . this will
show if and when the packet was last active and also the call sign .

Hi Les, N1LS
Do you know the EIRP used at 1296 MHz by DJ5AR or by PA3FXB
to complete the International Space Station-Bounce on 1296 MHz CW
QSO using the ISS as a passive reflector ?
Thanks for the information

Hi Domenico,
DJ5AR was using a 3m dish (29 dB gain) and 200 watts, PA3FXB also had a 3m
dish but I don't know the power output.
They each have a report on the QSO in the 432 and Above EME Newsletter

Hi Les,
As others have posted - 145.825 seems to be the frequency ISS has 'settled
on' for packet operations.
www.issfanclub.com is a great source of information for up-todate operations
with ISS, including frequency info.
If you have an audio interface between your rig and PC, it would be worth
looking at the likes of AGWPE:-
http://www.sv2agw.com/ham/agwpe.htm
This creates a 'virtual' TNC with your soundcard / audio interface and when
the audio levels are set correctly, it is possible to send and receive
packet via ISS.
UISS is a nice 'bolt-on' that can be used with AGWPE,
http://users.belgacom.net/hamradio/uiss.htm
This allows you to enter your grid square , or lat & long (there's also a
GPS plug-in if you operate mobile) and send postion/beacon/messages via the
APRS protocol.
Best regards
Matty

WOW !
From my modest EIRP calculation via the handbook that will be about
129130 W (129KW) (some error included...)
That's a huge power...

Hi,
I'm just in the process of release version 0.9 of HSD.
You will have to uninstall version 0.8 and re-install 0.9 because it has
a new signing certificate. (I have taken over ownership)
New features in this version;
Support for phones and 4/7/10 inch tablets
Landscape map for ground-track
IARU (Maidenhead) location input
The many other enhancements that people have suggested are
coming out in version 1.0.

Hello everyone. Just a quick note to anyone operating SO-50. I am extending
my apologies in advance for my operating practices. I realize after
listening to my videos that sometimes I May be talking over people
unintentionally. I am new at this, and hopefully learning from my mistakes.
SO-50 is so busy that sometimes I am not sure when a QSO has begun or ended,
and working with my HT and Arrow antenna sometimes get confusing at times.
Again, my apologies to everyone and hope to catch you on the satellite.

Again, thinking to FD...
- My FT-847 predates bi-directional CAT i.e. no computer assisted Doppler
- I may be the only one at the station i.e. no helper to man the antenna
(Arrow), so I may need to do everything.
- assume the transponder LEO birds
Has anyone tried this?:
1) mount a standard TV antenna horizontal
2) align the horizontal rotor axis 90 deg to the orbit
tilt (inclination?) of the intended bird (so if the
bird went directly overhead, a beam mounted on the mast would track)
3) but, mount the antenna on the horizontal mast such that it can be set
tilted off the mast
0 to 90 degs to the mast axis (from horizon to zenith, and in practice
set it to the maximum elevation of the intended pass)
4) operation: set the rotator (in 2) and aim the beam to the AOS
point of the pass (in 3), pan the orbit remotely from the operator position.
5) the rotator axis and angle of the beam to mast would have to be set for
each pass.

Bill, You are mistaken. The FT-847 will work fine with SatPC. I had one and
it worked great. I used a G5400 AZ/EL Rotor from Yaesu with the Easy Rotor
Tracker module from Germany. I also used the 12v voltage on the coax to
power my mast mounted Preamps. I know this doesn't answer your question but
trying to do an automated work around to the G5400 or G5500 is going to be a
real pain..
