Fw: Digital Slow Scan in space
by Graham Shirville 08 Sep '12

08 Sep '12

Hi All, We are looking for a practical system to use on a 1U, or perhaps 2U, cubesat to take medium definition images and transmit them to the ground on VHF for educational outreach purposes. All the usual cubesat mass, power, data budgets would apply but and I would especially appreciate advice and guidance about the best type of digital slow scan (or similar) system to adopt. I am aware of the SSDV system used on some balloon flights http://ukhas.org.uk/guides:ssdv Thanks in advance for all comments ideas and observations and especially any offers of support! 73 Graham G3VZV

Deciphering Phase 3D Telemetry
by Tony 08 Sep '12

08 Sep '12

All: I found a recording I had made of OSCAR-40's beacon on an old hard drive. I decoded the telemetry with AO40 RCV and found that it dates back to November 17, 2000. The status window shows that AO-40 was on it's third orbit at 15:11 UTC. I'd like to know the position of satellite when the recording was made and was wondering where I can find an accurate set of old Keplerian elements? Thanks, Tony -K2MO

Just heard ISS back on 145.825. Two students went outside with a D7 HT and sent themselves email using APRS via ISS. Came back inside and were amazed to see the Email in their inbox already! Now they understand APRS! Bob, Wb4APR

Thanks again for taking the >time to share your insights. We need someone like you on the board. As someone who has written an introductory article or two myself, I am inclined to agree. There is a lot of material that shows how easy it is to work your first satellite, but not a lot of "where to go from here". What would be nice is a tutorial which starts at working your first FM sat with a HT and portable antenna, then goes through from there in stages right through to fully automated stations capable of working a future HEO or fully automated operation on pacsats, among other things. 73 de VK3JED / VK3IRL http://vkradio.com
