MSNBC, 8 Apr 2012, James Oberg: "Far more authoritative than anything we report will be the post-launch detection of the [North Korean] satellite’s radio beacon by amateur radio operators in the outside world. Short-wave listeners are ideally placed to pick up such signals — first in Australia, and then along the west coast of South America, and finally up the east coast of North America. Only then will North Korea have its first chance to catch a fleeting signal, unless it managed an extremely long-range radio reception immediately after launch." Via The SWLing Post, 9 Apr 2012. -- Probably not on shortwave frequencies, though. The report below refers to frequencies in the UHF and X bands, above shortwave in the radio spectrum....

North Korea Tech, 20 Apr 2012, Martyn Williams: "The satellite will broadcast remote data in the UHF band and video in the X-band, the ITU quoted the DPRK’s notification as saying. The UHF band runs from around 300MHz to 3GHz and has several chunks of frequency reserved for satellite use. It’s commonly used by satellites to send data back to earth and is also utilized by the International Space Station and radio amateurs for voice communications. The X-band is a little more exotic. It runs from around 7GHz to 12GHz and is most often used via satellite for military and government communications."
