Set method of communication (5)

Ross

I believe the answer is:

radio

I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'set method' is the first definition.
'radio' can be an answer for 'set' (set can mean a radio set). I'm unsure of the 'method' bit.

'communication' is the second definition.
(radio is a kind of communication)

'of' acts as a link.

Can you help me to learn more?

(Other definitions for radio that I've seen before include "Communications device" , "Speech receiver" , "Electronic receiver" , "Marconi invented it" , "listening device" .)

I've seen this clue in The Globe and Mail and The Irish News.
