How vhf radio works?

Answer 1

A "ham" (amateur) radio station consists of two essential functional blocks in
addition to the licensed human operator ... a radio transmitter and a radio receiver.
The ultimate purpose of the package is 2-way communication with another
amateur station that is similarly equipped.

Except in certain few specially-authorized cases, one-way 'broadcast' transmission
is not permitted, so a typical communication follows this format:

-- By means of radio transmission, Operator 'A' announces his desire to establish
communication with another licensed ham (amateur) radio station. Operator 'A'
then silences his transmitter, and listens to his receiver.

-- By means of his own radio transmitter, Operator 'B' responds to Operator 'A',
then suspends his transmission and listens to his own receiver.

-- Operator 'A' responds to Operator 'B'. He informs Operator 'B' of his name and
location, possibly describes his radio equipment briefly, and tells Operator 'B' how
well or poorly his signal is being received.

-- Operator 'B' then delivers the same information to Operator 'A'.

-- At the mutual option of both operators, they may end their communication at
this point, or they may continue it for many hours, discussing their mutual
interests in certain technical minutiae of radio communication, their other hobbies,
their occupations, their station in life and career, their families, their vacations,
their literary and musical interests, religion, political tendencies, tastes in food and
fine wine, etc. Exactly like two individuals who meet in a bar or on a train, except
that these two may be separated by half of a world, and have met on ham radio.

And that's how ham radio works.
