Version 4.2 of OH5IY's meteor scatter software has been released today. I have uploaded it into ftp.funet.fi: pub/ham/vhf-work/mssoft42.zip. V4.2 has lots of improvements and changes compared to V4.1. The most exciting new feature is true, measured activity of major showers. The graphs show the profile of each shower 96 hrs around the peak. This is something you really want to lay your hands on !! Other new features or changes include: - bar graphics ZHR history for major showers since 1980. - updated shower data and improved peak calculation algorithms. - meteor speed correction factor used in computing ant. elevation. - sidescatter optimum elevations computed. - day scanning on gradient curves with EGA&VGA. - single screen shows all numeric gradient data. - improved text editor and find function in sked-editor. - improved install and default parameter setting program. - better error handling. - mouse control. - creates \ms and \msdata subdirectories - installs on any existing subdirectory. - report can be sent 2 or 3 times on CW. There are many new features not listed above. See readme42.com to find them all. If you are using this software, send a message to OH5IY for his records. If you send your packet or e-mail address, you will get the new data files automatically after each shower. OH5IY's e-mail and packet addresses are mentioned in the end of readme42.com. If you can't ftp but want a copy of the new version, send a formatted 3.5" HD disk with 4 IRCs (or equal amount of USD) inside Europe, 6 IRCs outside Europe, + Self Addressed Envelope (SAE) to Ilkka Yrjola OH5IY, Jukolan tie 16, FIN-45740 Kuusankoski, Finland. The first copies of the new version will be mailed out this week. The latest version is always available by anonymous ftp at ftp.funet.fi (128.214.6.100): pub/ham/vhf-work/mssof*.zip. The new versions will named as mssof421.zip, mssof422.zip, mssoft43.zip etc. (Hint: use pkunzip -d to open the .zip file). In future look also for msdata94.zip, which will contain all new data files. It will be updated after each shower. -- Jukka OH6DD jsi@hut.fi ------------------------------ Date: 20 Apr 1994 21:41:09 GMT From: ihnp4.ucsd.edu!usc!nic-nac.CSU.net!charnel.net.csuchico.edu!charnel!olivea!news.bu.edu!dartvax.dartmouth.edu!usenet@network.ucsd.edu Subject: QRP satellite work To: ham-space@ucsd.edu I've been thinking of getting into amateur satellite work lately. Just sort of rummaging through my AES catalog as a general benchmark for prices, I've decided that the "top-end" satellite station, from what I've read would be something like a Yaesu FT-736R transceiver, a Yaesu G-5400B alt/az rotor w/ computer interface, a pair of KLM circularly polarized yagis, a fiberglass boom, some sort of mount, an amp/preamp, 15 to 30m of Belden 9913 and 8448 cable, a PC to run the rotor controller software and tracking software, etc... around $5000US or thereabouts. Which is about $5000 more than what I have to spend right now :-) My current setup is used mostly for packet and consists of a macintosh computer, an unmodified Alinco DJ-580T, a KPC-3 TNC, an Astron RS-20A, and a Hustler dualband base station vertical at about 15m above ground. My question is what sort of satellite work can I do with this setup? Anything? What sort of supplements could I add to it to work sats? From what I have read so far, almost all of the satellites seem to use SSB/CW. Can anything be done with FM? How does packet work? In general, can anything be worked with a vertical ground plane antenna, or do you have to use yagis with alt/az rotation? Is anything workable on 5W, or would I really need an amp/preamp? In short, is there anything I can do with my current setup, or should I wait for five or six years until I'm out of school and can afford to invest in this sort of equipment? --- ======================================================================= Kenneth E.

I agree that single-maintainer distribution for FAQ's and bulletins is desirable under most circumstances. The down side is that a single maintainer is also a single point-of-failure. A very powerful technique for allowing multiple posters without duplication at any site is available within Usenet news (essentially a hack of the Message-ID, similar to the BID system on amateur packet radio). Currently the rec.radio.info moderator coordinates several posters of ARRL bulletins, mapping the packet bids to Usenet Message ID's. For example, ARRL Space Bulletin 20 with a packet BID of $ARLS020 would map to: Message-ID: <$arls020.1994@ampr.org> Technically, Message ID's should contain the domain of the originating station, but since users from several domains may post the bulletins, and ultimately the bulletins may be considered to originate from amateur packet radio, making ampr.org the domain resolves the issue without subverting the intent of RFC 1036 too much (the addition of the year to the BID makes it unique indefinitely, which RFC 1036 strongly recommends). Since the orbital elements have their own BID convention (starting with $ORB), such a multiple-poster arrangement can be used for them as well. If anyone is interested in becoming a volunteer "bulletin station" for Usenet for any bulletins with BIDS, contact the rec.radio.info moderator at rec-radio-request@ve6mgs.ampr.ab.ca. In this way, we can keep the information flowing fast and regularly without burdening any one person or small group of people too much while avoiding unnecessary duplication. 73, Paul W.
