I've been getting ready for the November 24 launch of the CubeSat that Farhan and his friends in India built. I started out with my trusty Drake 2-B and a Hamtronics 2-to-10 downconverter, but I quickly switched to an RTL-SDR dongle and HD-SDR software. My 3 element quad antenna is visible in the first video. So far, I am using the Armstrong method to turn the antenna. In that first video I keep saying that I am waiting for AO-71. In fact is was AO-73, the "FunCube" from the UK. I think it is similar in power and antenna configuration to Farhan's satellite, so I think we are almost ready for launch. (Any ideas on what that mysterious pulsating sig in the satellite passband signal is in the first video?)
