OOPS!! In my previous posting, H-S Digest #179, I made mention of
crossed Yagis. I really meant "crossed dipoles". If I had the
ability to put up beams, I wouldn't have the need for a fixed
antenna. I found something about this configuration in an old copy of
The Satellite Experimenters Handbook with the name T/R Array (for
turnstile-reflector) The diagram showed two patterns, one like a
slightly elevated do-nut and the other more rounded but slightly
elongated in the vertical plane with the difference being only the
spacing above ground. The do-nut was 3/8 wave and the other was 1/4
wave above. Also, the antenna was illustrated for 2M, but shouldn't
it work for other bands as well? Again, thanks in advance for any
input.

To: ham-space@ucsd.edu
I just finished creating a simple (but effective) telemetry decoding program
for DOVE-OSCAR-17 and am making it available via anonymous FTP at
pilot.njin.net. The file is called "duvdec10.zip" and is located in the
/pub/SpaceNews/software sub-directory.

Yes, DO-17 is the same satellite as DOVE. At the moment, the bird is transmitting
on 145.825 +/- doppler. It is broadcasting AFSK 1200 baud packet (standard TNC will
capture and decode) and computer generated voice announcements. At this time, the
computer generated voice is simply saying "HI, this is DOVE in space" or something
like that. A little difficult to understand. Good luck.

i'm trying to put together a first sat station ... right now i just use a
2 meter mobile rig, power supply and 3 element beam. i know about 726's
and 736's, but i would like to enter the hobby at a less expensive level.
seems that there are 2 meter and 430 mhz multimodes that were used for sat
comm before the fancy newer rigs ... anyone have suggestions for entry
level stuff?

To: ham-space@ucsd.edu
A recent AMSAT bulletin listed a live rebroadcast of the Houston AMSAT net
to take place on television satellite G3 transponder 17, 5.8 Mhz audio
channel at 10:00 PM last Tuesday night. I couldn't find any audio on 5.8
or anywhere else on transponder 17. Messages left at the phone numbers
listed in the bulletin for information have not resulted in any return calls.
Does anyone know if the rebroadcast was on another sat, freq, or time?

Hi,
I am an amateur astronomer and often wondered if it was possible to identify
the satellites crossing the night sky. If anyone knows, I guess you guys
should know.
So, would anyone be so kind and send me the coordinates, dates, times...
I am at long.68*26, lat.+47*28.
I will appreciate very much.
Thanks.
Rachel
