The latest episode of the HAMRADIONOW.tv program discussed the Fox Project at AMSAT-NA, which aims to build a “family of CubeSats with amateur radio transponders that can support advanced science experiments” for students : HamRadioNow – Episode 85: AMSAT Fox-1

Getting a launch date for a new satellite – even a date more than a year out – is exciting at AMSAT. In this episode, we talk to a pair of AMSAT VP’s. Tony Montiero AA2TX handles Engineering, and Mark Hammond N8MH does Education. We talk about what Fox-1 will do (an FM crossband repeater that will also relay data from onboard science experiments). And we learn how AMSAT must transition from a bunch of hams who put up satellites that we can talk through, to a provider of the physical platform and communications for educational experiments for school grades K thru Post-Grad…. that also has transponders and repeaters that hams can use.

The site websdr.org provides a long list of online SDR (Software-Defined Radio) sites:

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.

For example, the following site tracks several satellites and the ISS and has a “sat” setting for tuning them in: VHF/UHF WebSDR on University of Technology Eindhoven – Maxwell Foundation (Note the site requests permission to run a Java program in your browser.)
