[QUOTE="Analoguesat, post: 1049321, member: 176362"] Last night whilst idly keeping half an eye on the waterfall spectrum on sdr# I spotted an out of band "APT like" carrier around 136.650MHz. After a bit of research it turns out its actually Transit 5B-5. Which was launched in December 1964 and abandoned after an on board failure after just 19 days! So its another zombie sat. Sadly its not a new discovery - its quite well known about, but as its only transmitting a carrier with no data most folk dont bother with it. There are a few web pages about Transit 5B-N and the other zombie birds that are out there. However I found this absolutely fascinating - its reckoned to be the oldest satellite still at least partially operational. Not bad for a satellite almost 54 years old! The pic shows the carrier mid pass tonight about 2155 uk time. [ATTACH=full]116894[/ATTACH] [/QUOTE]
