STS-130 S-Band phase modulated downlink
Submitted by pjm on Fri, 12/02/2010 - 16:25.STS-130 s-band down link captured on 2217.500MHz directly from the orbiter. The FFT screen shot shows the typical modulation format in use. Sound files recovered from this down link have been posted to http://www.uhf-satcom.com/sounds/
The BPSK down link from the orbiter was captured with an RF-Space SDR-IP ethernet radio.
NEW AOR AR5001 receiver
Submitted by pjm on Thu, 11/02/2010 - 22:27.
New AOR receiver, presumably replacing the AR5000. This one covers 40kHz to 3150MHz - nice! Its been suggested that the AOR AR5001U List Price is $3799.00. My guess is that the spec is similar to the AR2300 since it would not make economic sense to build nearly identical RF units for 2 separate receivers - pure speculation of course ;-)

ADS-B receiver project by Vinculum
Submitted by geraki on Wed, 16/09/2009 - 07:45.A group of people at have for some time now been analyzing ADS-B specs, and the construction of commercial ADS-B units (AirNav & Kinetics). Under coordination of "Vinculum" they are now trying to make their own version. From the information released on the website there is a working prototype at this moment giving very good results. If and when this project comes to an end, the fruit of this effort will be sold as "kits" with PCB, filters etc for a two digit figure (euro)!
1090 Mhz ADS-B Receiver project info page. Unfortunately the whole discussion and website is in German. The developer needs to know how many people would be interested to buy such a unit, to place the proper orders for the components etc, and also help to keep the per-unit-price down. If you feel you want to experiment with ADS-B send him an email: webmaster_removethis_@jetvision.de telling him you would be willing to purchase one (or more). There are already twenty people on the list.
