This was my first time ever running V/s portable. I was working with the
W1MOO crew in VT.
We used a K5GNA AIDC with front mounted dipole and little corner reflector.
It was handheld for the entire pass. FT-817 IF. Worked 3 stations with
excellent signals!

I'm trying to write my own pass prediction program for tracking FM
satellites. This program will this notify the users of upcoming passes
via APRS messaging. I would like to find an algorithm that will predict
AOS/LOS time and azimuth and the maximum elevation. I'm also hoping
this algorithm will not be too computationally intensive as it may
possibly be used for hundreds of different station locations.
Can anyone help?

I have had my SatPC 32 up and running for long time, all modules seem to
work fine except the CAT. It wont take control of the Icom910H and track
the doppler.
When I designate a particular satellite and click on the "C" for CAT
control, the s/w connects to the radio and the Icom receives some bogus
frequencies and mods , that don't correspond to the selected satellite
(doppler file). I have re-checked all of the configuration setting !! ???
The S/W seems to be talking to the radio, but not with the right frequencies
and doesn't track these frequencies once they are loaded.
Any suggestions. Thanks , Bob -kb5yzg tel (828) 696-4103

I'd suggest looking at books on spacecraft mechanics.
One which may help is "Fundamentals of Astrodynamics" by Roger R. Bate,
Donald D. Meuller, and Jerry E. White (published by Dover). It's one of the
better books on the subject, in my opinion, as I found it easier to read
than many of the others I've seen. One does need some familiarity with
calculus and linear algebra in order to understand the theory, however, but
it's not overwhelming.
Another one is "Modern Spacecraft Dynamics & Control" by Marshall H. Kaplan
(published by John Wiley & Sons). It's good, too, but I didn't find it as
easy to go through as the other one.

Heard today of a Passive HF relay satellite being proposed.
Wondered if Hams could relay off of it.
It's a 10m diameter sphere.
I assumed a 10m signal and 1000 Watts
And antenna gains at both ends of 10 dB.
Unless I made a dumb error, it looks impossible?
I get a received signal of -170 dBm
Compared to a good HF receiver of -122 dBm
So its 48 dB down in the noise.
Going to narrow band, could improve things, but the Doppler of
+/- 600 Hz would make that difficult.
Anyway, if someone else wants to double check the link budget
using the radar range equation, go for it.
The beauty of this system is that it is perfectly spherical, so
the reflection coefficient would be constant within 1 dB. That
is the advantage over trying to use the ISS or other large
rocket body... They vary by 20 dB making communication by
reflection impossible.
Oh, and it would be in space for 30 years or more. So with
something that reliable, it would be worth developing an amateur
capability to use it.
It is not designed for comms, but as a calibration sphere for
over the horizon radars that have LOTS more power and LOTS more
gain than we do.

First, are you using a "real" serial port or a USB-to-serial
adapter???Second, have you confirmed?that the software and the radio are
both set to the same baud rate and device address?? And finally, what CAT
delay setting are you using in SatPC32?
Mine works perfectly with either type of interface at 9600 baud, default
address of $60,?and a CAT delay of 70.

My suggestion is that you start from "Predict", an open source satellite
