I've worked terrestrial packet for some time, but I have only recently given working the PACSATs a try (after much trial and error, I recently downloaded a file from AO-16 for the first time). I am looking for insights into optimal use of a 2232 with satellites, especially AEA upgrades, hardware and software mods, and tips and techniques you found particularly useful. Also, if there is a 2232 UG/mailing list/forum, I'd like to know how to join/subscribe. I seldom get onto UseNet, but if you have the time and inclination for direct email, you can reach me at: marcoh@world.std.com n1mae@amsat.org n1mae@switch.lmnstr.ampr.org mny tks et 73 de n1mae Mark "Marco" Heroux ------------------------------ Date: 1 Sep 94 18:06:23 +1000 From: agate!msuinfo!harbinger.cc.monash.edu.au!news.cs.su.oz.au!metro!usage!csdvax!u1066579@ames.arpa Subject: Help wanted with decoding telemetry To: ham-space@ucsd.edu HI, I am interested in the possibility of decoding the telemetry from weather satellites. Can anyone help me with this? If so please e-mail.

Subject: Mir Checkpoint #734 To: ham-space@ucsd.edu MacSPOC Users- The enclosed checkpoint reflects tracking of Russia's Mir space station late Wednesday night CDT. Over the past few days, Mir's orbit has been changed repeatedly. A Progress resupply vehicle launched last Friday has made 2 unsuccessful automated docking attempts with Mir, and a third attempt is to be made under manual control from Mir's crew this Friday. Under standard Russian docking procedures, the attempt would be initiated around 8:38 AM CDT Friday. Fuel reserves aboard Progress are nearly exhausted, although a fourth attempt may be possible. If a docking is not performed, however, Mir would have to be abandoned in about 2 weeks before her crew ran out of food. Without a crew, Mir's fate is unknown. A major reactivation effort was required after Mir's Salyut-7 predecessor was abandoned in 1985. -Dan Adamo ============================= File: Mir-734.cp ==============================cut here================= Orbit 48786 ElSet 734 on 09-01-94 1994 244 ( 9- 1) 0 0 .000 1994 245 ( 9- 2) 0 0 .000 0.244959750068D+07 0.595010451348D+01 348798 0.548704952642D+07 -0.147855739048D+08 0.156357784745D+08 0.236355277376D+05 -0.432430004354D+03 -0.867535713518D+04 90.0 5000.0 79.00 2.72 ==============================cut here================= 73 for now.... c u on the shortwaves Terry Stader - KA8SCP America Online Ham Radio Club Host Macintosh Amateur Radio Software List Maintainer Internet: tstader@aol.com (e-mail) or tstader@si.tiac.net (binaries/files >28K) KA8SCP@WA1PHY.#EMA.MA.USA.NOAM ka8scp@ka8scp.ampr.org [44.56.4.82] ------------------------------ Date: Thu, 1 Sep 1994 19:46:03 +0000 From: ihnp4.ucsd.edu!newshub.nosc.mil!crash!news.sprintlink.net!demon!arkas.demon.co.uk!Michael@network.ucsd.edu Subject: Rain attenuation of satellite downlinks To: ham-space@ucsd.edu This might not be exactly amateur radio, but perhaps there is an avid satellite tv dx'er out there who can help ... I am interested in obtaining measured rain attenuation figures for C-band downlink (4 GHz) signals from communications satellites in the South-East Asian tropical region. I'm looking to compare typical, real-world attenuation values with those predicted by the CCIR model. Can anyone point me to where I may find such information? I would prefer an Internet source, but printed references would be ok. Emailed messages to michael@arkas.demon.co.uk would be appreciated.
