- 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.

- 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,

- 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)
