K4T operation

Hi, If you need Dry Tortugas, give them a try, almost any satellite and pass. They are on the air with a first rate satellite station. An earlier problem with the 70 cm downlink is fixed. So far everybody seems to be playing nice by being patient. 73s, Alan WA4SCA

K4T Audio 12March 1156z 435.150
by John Papay 12 Mar '10

12 Mar '10

The K4T Audio Recording from this morning's pass is on my webserver. They were on FO-29 30 minutes later but their signal was weak. Right now they are working ssb on 14260. http://www.papays.com/AO-51_12Mar2010_115613z.mp3 They are having some antenna pointing problems but have been working through it. Lots of satellite contacts are in their log. Great job! 73, John K8YSE

Hypothetically speaking, if you had an FT-857 and wanted to work satellites full-duplex, what would you pair it with? Another 857, an 817, something else? Thanks, Joel, W4JBB AMSAT #32589

Wallops ADAMSat Launch Thurs 7-9 AM

But they decided to go through > the preparations and launch if the cloud breaks > just enough tomorrow. > > Wallops Launch team will be "tweeting" about all > the launch news or delays as they happen on: > > http://twitter.com/KyspaceADAMASat APRS stations can receive Launch announcements even while mobile via the APRS CQSRVR. Just send APRS message to CQSRVR beginning with the group name CQ WALLOPS ... (for info on cqsrvr see www.aprs.org/cqsrvr.html Remember, Point beams towards Wallops and capture all data on 144.39 1200 baud for the duration of the flight! Which should be visible over most of the mid-atlantic states. Callsign will be KJ4HVJ. The sounding rocket with amateur satellite operates on 144.39 MHZ APRS will rise to 100 miles or so for an 8 minute mission. The payload is called SOCEM/ADAMASat. There is a computer program and GUI to interface to your PC so you can grab the telemetry live. It is on: http://ssl.engr.uky.edu/adamasat_free_gui.exe It's a one shot deal, so I'm gonna have a backup TNC and HYPERTERM collecting everything. ADAMASat is the Antenna Deployment and Mono-filament Actuator Satellite. It's a 2U CubeSat designed by Kentucky Space as part of SOCEM, the Sub-Orbital CubeSat Experimental Mission. ADAMASat, which is scheduled to launch on Hall 12.067 out of Wallops Flight Facility on 11 March, will fly in space for roughly 8 minutes performing an engineering experiment and transmitting data down to Earth via APRS packets. More information on ADAMASat is available at http://ssl.engr.uky.edu/suborbital/adamasat Kentucky Space is hereby releasing to the AMSAT-NA community the ADAMASat FREE GUI, a free 32-bit Windows binary for amateur radio operators in the Eastern United States who are interested in tracking ADAMASat on its launch day. The GUI is a standalone application and upon opening it on his/her computer, the HAM will be greeted with a popup window which explains the steps required to track the payload. All that is needed is a Windows machine, a radio and TNC which can receive on 144.390 MHz, a serial or USB cable, and a suitable location. The GUI parses the APRS packets as they are received, graphing temperatures on-board the payload and reporting status of the mission in real-time. It also includes instructions on e-mailing the packet log to Kentucky Space to aid in post-processing, and a built-in aggregator for the official ADAMASat Twitter RSS feed. Disclaimer: Kentucky Space provides the GUI "as is" without warranties of any kind, and shall not incur any liability for any damages connected to the use of the GUI.

AO-51 pass 1411 utc 3/11

Drew and the AO-51 Crew. Did you do a power change on Echo?? The pass this morning, was very weak, even at 1150 km distance (40.7 deg), as never got over S2 where here lately has been S7 (no external preamp). Just curious. John W6ZKH
