Get ready to put TV channels into effect? (6,8)
I believe the answer is:
action stations
'get ready to' is the definition.
I can't judge whether this definition defines the answer.
'put tv channels into effect?' is the wordplay.
I cannot quite understand how this works, but
'put' could be 'station' (I've seen this before) and 'station' is found in the answer.
an anagram of 'into' is 'tion' which is within the answer.
The remaining letters 'acs' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for action stations that I've seen before include "military positions" , "Warning to be ready" , "Get in position to fight" , "Warning to take up position" , "ready for a fight!" .)
