When the web page was created, the keps got pasted wrong. Use the Keps from the cubesat.org page, they work.http://www.cubesat.org/ 1 99999U 00000 11063.43259919 0.00000000 00000-0 00000-0 0 0000 2 99999 97.9564 8.4412 0007658 67.0214 113.6793 14.77265551000000If this copy does not work, go to the cubesat.org page.

Great camera footage from last month's Shuttle launch. One camera is mounted on an Solid Rocket Booster. At 2:28, it separates ... and you watch it splash back into the ocean. The next camera was mounted watching one leading edge of the Shuttle's wing. Grab a cup of coffee ... http://www.nasa.gov/multimedia/videogallery/index.html?media_id=68551231 Clint

This is cool. Don't know if I want to get up at 0500 to watch it though but folks over the pond can sleep late and still catch it live. http://countdown.ksc.nasa.gov/elv/index-vafb.html Charlie KI4RDT

Going to offer this here before putting on QTH.com Arrow 146-4S solid element antenna with "N" connector. New, in the shipping bag. I ordered before I found another set of antennas. There is about a month backlog to get antennas from Arrow, busy place. These sell for $60 plus shipping and handling of $15. I will sell for $60 shipped to US only. Paypal or USPS money order. 73 Bill K3SV

Re: AMSAT Fox News
by Trevor . 03 Mar '11

Hi Tony, That's great news. Are you able to say what the power budget overhead is in having an SDX transponder? The most efficient SDX I'd heard of still consumed some 310mw more than an analog linear transponder which for a conventional 1U CubeSat is 310mw too many. SDX on a CubeSat with deployable solar panels paves the way to using far higher speed telemetry downlinks than we currently achieve in a 20kHz B/W. 73 Trevor M5AKA --- On Thu, 3/3/11, Anthony Monteiro <aa2tx(a)comcast.net> wrote: > From: Anthony Monteiro <aa2tx(a)comcast.net> > Subject: Re: [amsat-bb] Re: AMSAT Fox News > To: m5aka(a)yahoo.co.uk, amsat-bb(a)amsat.org > Date: Thursday, 3 March, 2011, 0:51 > Hi Trevor, > > The AMSAT Fox CubeSat bus will include both an analog FM > transponder and a software defined transponder (SDX.)
