What happens is the zone of silence?

Radio and television waves do not travel- it is difficult to explain, as they can use radio in outer space- look at satellites and moon shots. There is someting in the Zone of Silence which effectively blocks all NORMAL radio and tv reception and transmission- the author Childress seems to imply there are some frequencies ( my guess secret) that are not effected by this weird, nature-imposed blackout of radio waves.

What is a transmission mode?

In radio we would have: Phone ( voice and music)- AM, FM, Citizens Band, SSB (Single side band)- then CW ( continuous wave) for code transmission, such things as Facsimile, Telex over radio ( Radio-teletype). which are entirely machine-generated like a typewriter keyboard, and so on... Television is a form of transmission mode- but is not radio but well, Video.
