Interesting...the article posits, if frequencies can be discovered, it might be possible to intercept/capture transmissions from the satellite, when in range, using something as simple as a ham radio or SDR dongle (police scanner)...<p>My understanding of satellite coms is that many satellites are of the "relay" class, and use TDRS--Tracking and Data Relay Satellite--to bounce signals from satellite to satellite when a ground station is not in line of sight...NASA, for instance...<p>I wonder what the N. Korean coms protocol is...?
