A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies or handie-talkies.
Two-way radio systems usually operate in a half-duplex mode; that is, the operator can talk, or he can listen, but not at the same time. A push-to-talk or Press To Transmit button activates the transmitter; when it is released the receiver is active. A mobile phone or cellular telephone is an example of a two-way radio that both transmits and receives at the same time (called full-duplex mode). It uses two different radio frequencies (channels) to carry the two directions of the conversation simultaneously.
Installation of receivers and transmitters at the same fixed location allowed exchange of messages wirelessly. As early as 1907, two-way telegraphy traffic across the Atlantic Ocean was commercially available. By 1912 commercial and military ships carried both transmitters and receivers, allowing two-way communication in close to real-time with a ship that was out of sight of land.

Who drew the lines that say
That it has to be one way
You and me's a two-way thing
I can feel a spark
when you're touching me I start
To realize how hot this could be
If you want me tell me so
Don't make me wait too long
I need to hear it from you
So what you wanna do?
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
And what we make comes from you and me
Who says you have to call
Be the one to set things off
See I don't wanna wait for you
'Cause this feeling inside
Is something I won't hide
Until I'm sure you're into me too
Boy I've told you what I want
Don't make me wait too long
I'm ready for you
So what you wanna do?
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
And what we make comes from you and me
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
And what we make comes from you and me
You don't have to follow me
Let me know whatever you want
No need
That's where I'm gonna be
Love's a two-way thing
You and me
A two-way thing
Love's a give and take
What we make
You and me
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
And what we make comes from you and me
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
And what we make comes from you and me
Love is a two-way thing
Where we begin is up to you and me
Love is a give and take
