Let me summarize what I think was said in answer to my question; Is
there any way to get a linear transponder on the ISS?
1.) There is already a transponder on the ISS albeit an FM U/V one.
2.) It is not in use because it is either:
a.) a 'power hog' or
b.) it is not functioning properly or

I believe it overheats
c.) NASA does not want it functioning as an open repeater.
Why can't they set it to only open on valid CTCSS?

hi amsaters, i will be going to the Wyoming State ham fest in buffalo in the
northern part of the state,
dates will be june 6 and 7th, 2013 grid DN64 and could go down and over to
other grids if requested,
i would like to setup sceds on any of the operational satellites, those
stations needing

The nicest configuration... would be a 2m FM uplink with CTCSS to avoid

The problem with that is the same as all our other FM satellites. Only a
single user at a time. Congestion, conflict and little practical value.
The better use of SSB is to use the

I am working on a summer project with students at Montgomery College,
Rockville. The project is to design and build a device that controls a
pair of inexpensive satellite TV rotors. And the device would emulate a
popular AZ-EL rotor such as a Yaesu G-5500 AZ-EL controller so it can

Hi Jari OH3UW
Looking at the last two crossed yagi designed by Mak on the
bottom of the Mak's page it seems to me that looking from
the reflector in direction of beaming the green dashed circular
sense of polarization is rotating reversed so that the CW
polarization seems to rotates CCW and

following passes this weekend.
Sat. from FN54 at 1704z and 1844z
Sun. from one of the following FN54, FN53 or FN43 at 1731z and 1912z

Hi Domenico,
Thanks for your interest in the ISS reflections
Now about your questions.
1. I started calling Andreas as soon as my dish could see ISS.
That was on May 23 at 8 degrees elevation.
So the distance would have been close to 2000 km at that time.
Andreas reports that he
