April 2012 - Shortwave Radios, Satellite Dishes and Internet YouTube
Why do we still need shortwave radio? The satellite dishes (C-band, Ku-band) were the way to see the video programming, and satellite feeds. The Internet / YouTube seems to have replaced the role of satellite.
Does broadcasting (radio, satellite) still has its advantage over the Internet (point-to-point) service? In the time of disaster, what will work? Is cellphone going to perform better than radio?
