Delfi-C3 TLE's
by Wouter Jan Ubbels 28 Apr '08

28 Apr '08

Hi all, w.r.t TLE's for Delfi-C3, for now we advise everyone to keep using the "old" TLE's as published on our Mission Operations Page at http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=1… These seemed to match best on the last good pass over our groundstation this afternoon. 73!

New cubesats monitoring result

Hi all, Monitoring the pass during 12:58 - 13:12 UTC over Taiwan, max. elev.=80 deg. Copied 3 cubesats CW signal as following: *CUTE 1.7+APD II 437.275 MHz cute86cba367382825ac643017 compass-1 **437.275 MHz compass29000000000000001602c31508 SEEDS 437.485 MHz jq1yguseedsg0d85ffe jq1yguseedsg0d28ffe jq1yguseedsg0d10ffe Compass-1 sounded a little bit weird! 73 Edward / BX1AD ----- P.S. I also recoded the frames **mentioned above. *

Correction: New Satellite Observations.
by Colin Hurst 28 Apr '08

28 Apr '08

Having listened to a recording of the pass mentioned below, the chirpy signal is crystal locked, but the doppler shift deviated significantly from the auto-tuning, which suggests the keps in use need some refinement. Unfortunately the two signals are only 300 Hz apart. >From the chirpy signal I was able to decode from the start of a sequence 00C01.A..29000000000000000.502C5... Apologies about jumping to the conclusion about the crystal. Colin VK5HI -----Original Message----- From: amsat-bb-bounces(a)amsat.org [mailto:[email protected]]On Behalf Of Colin Hurst Sent: Monday, 28 April 2008 10:41 PM To: amsat-bb(a)amsat.org Subject: [amsat-bb] New Satellite Observations. Observations from the pass 1242 UTC to 1255 UTC, over VK. Copied two CW signals on nominal 437.275. One was very unstable and chirpy with slow CW, the other was clean, fast CW, but quite weak in signal strength. The unstable signal drifted down the band very quickly, definitely not crystal locked. Also copied SEEDS on nominal 437.485, but may be slightly lower in frequency. Signal clean but very weak. Visible on Spectran but not decode-able. This pass was in Eclipse. Used auto-tracking throughout the pass, which may have been a retrograde move. Colin VK5HI. _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Hi All can anyone recomend a doppler tuning program that will tune the ft847 in 1hz steps ,at the moment I am using Instant Tune but thats only 10hz as is HRDRegards Robert G8ATE _________________________________________________________________ 100’s of prizes to be won at BigSnapSearch.com http://www.bigsnapsearch.com
