Darn Nada heard on an excellent pass of the ISS at 1106PM PDT.
But I think the astronauts were just awakened at the top o' the hour.
OK - 5:30-ish AM PDT next pass over Southern CA DM13-land!

In low power mode, the transmission is started clean
every time. A single telemetry data frame is only 256
bytes so about 4 seconds of data. After the 1 frame, the
transmitter is left on until the interleaver is emptied.
Excellent. I don't think anybody ever told me this. I'm glad somebody

Bernhard,
Nothing down here at EM65 on the 1102 UTC pass. Good geometry, though.
Fingers crossed we will have some definite word today.

I saw on this bb a site or note that shows the overall
average elevatation. As I remember it elevation is
surprisingly low for most passes. Where can I find it?
I have a sketch on my web page: http://aprs.org/rotator1.html
It shows that 70% of the time LEO satellites are below 12

The US crew was performing routine EVA battery charging yesterday in
preparation for the EVAs to be performed during the next shuttle mission. I
think that has gotten folks confused because of all the discussions on KEDR

I am curious why we need 100 reports that a signal was not heard? Would it not
be more beneficial to post nothing unless a signal was actually heard thereby
reducing the number of posts to the bb? also, please reply to this message

Back in the goode olde dayes (i.e. OSCAR VI and OSCAR VII), before elevation
rotors were popular, we used a horizontally polarized yagi fixed at 30 degrees
above the horizon. That worked very well even for overhead passes.

Thanks for the confirmation. Yes, elevation rotation is simply not needed
at all for LEO spacecraft and modest beams. A mild, fixed tilt modest beam
is just perfect.

30 degree up tilt and it worked well...
Lessening the up tilt may increase the gain
for the lower angle passes but will also decrease
the gain on the higher angle passes. So, it is a

Gentlemen,
Your difference of opinion may stem from the fact that AO-6 through AO-8 had
orbits that were in the 1450km range, and not the 600-800km that is more common
now. That might hose up the numbers some, as the angles and path losses are
considerably different.

Bob etal,
Your discussion has prompted me to throw up a yagi (2m7) quickly in
anticipation of ARISSat-1. Viewing ISS from Alaska is much
simpler: Just point due south on the horizon as ISS rises no more
than 15 deg and usually half that angle. Living near 61 deg N
latitude makes the ISS

Right, it's conventional CW, mode A1, with the carrier switching on and off.
A2 would be considerably less power-efficient.
ARISSat-1 also uses the CW beacon as a tuning reference for the BPSK-1000
digital beacon. The BPSK beacon is centered 1 kHz above the CW beacon so
that the CW beacon sits in
Somewhere I still have an OSCAR locator. That is why several locals came up
with a computer program to run on a mainframe to calculate the elevation and
compile a set of tables. MUCH easier!
