To: ham-space@ucsd.edu
This is probably the wrong news group to post this in.
If so, redirect me, please!!!!
Anyway, the show 48 Hours last night broadcast about
the search for UFO's. I found most of it rather hokey,
and (in all honesty) rather humorous.
What got my attention, however, was the segment on the
radio-telescope facility that was scanning the skies in
search of hopeful radio contact, or sounds, or, well,
anything out of the norm. They had 37 signals they
could not identify.
Now, my question is, does anybody know what frequencies
these 37 signals were heard on? I'm just curious.
Please e-mail me at FSRLA@aurora.alaska.edu
Thanks!

You did not mention anything about frequencies. You can not use
amateur radio frequencies just because you have a license! There are
licensing procedures etc.

Subject: Orbit DETERMINATION software ??
To: ham-space@ucsd.edu
Hi all. In recent weeks I have searched many ftp sites for orbit
determination software - that is, software for calculating the orbit
parameters of the sattelite given data such as measured Ra and Dec from
a given ground stations(s), or doppler (i.e. velocity) readings from such
stations. While there are many excellent shareware packages available for
orbit calculation or tracking (that is, given the orbital parameters where
will the sat be at time T), I have failed to find any for my 'Inverse'
problem. Any info will be of help.
Thanks,
Zvi

rec.radio.amateur.vhf.plus should it be created?
This is a informal request to see if there is enough interest to warrant a
new news group. The driving factors in this interest are, the apparent
demise of the vhf list run out of Stanford University and the lack of any
other news group for this area. The major unknown is if there is enough
interest to set up a formal RFD/CFV for this area.
While my primary interest is in the weak signal area, I have also noticed
a general need in areas of ATV, Repeaters, FM, etc. So I envision the
charter as being read very broadly, to include all areas of VHF/UHF/SHF
interest, except RC, satellite, and packet (as they have their own forums)
Please reply to me via email or to rec.radio.amateur.misc (also posted to
rec.radio.amateur.space and rec.radio.amateur.policy)

It's done and working. LISTSERV requests should go to:
