No, of course not.
Wavelength
transmissions
Amplitute Modulation signals. a modulation(mixing)method used in early radio transmissions.in many countries, radio transmissions below 30 Mhz,are still using this method.short wave,medium wave transmissions,and some extent of VHF transmissions are possible in this method.
Chances are, the building you're in has a metal roof. This will block almost all radio transmissions.
No, not under normal circumstances do RF devices cause headaches. Radio frequencies are all around you at any given moment in time. Standard devices that you use everyday such as a radio (car, home, or walkman) or cordless phone pick up and use these radio transmissions.
A radio that receives Frequency Modulated (FM) transmissions.

Yes, they can monitor and decipher.
CONTACT! Example (US radio transmission): "Lima 6 this is Mike 6 we have contact over!" Further transmissions would follow...normally with audible gunfire in the background of the radio transmissions.

Radio is spelled the same in Spanish as in English. It is pronounced, "RAH-dee-oh."
The 509 RRG was an Army Security Agency unit [formerly called the 3rd Radio Research Unit] that did radio detection of Viet Cong radio transmissions.
