Appealing deception on cable radio (7)

I believe the answer is:

likable

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

'appealing' is the definition.
(I know that appealing can be written as likable)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for likable that I've seen before include "attractive" , "Easy to take to, of pleasant personality" , "Amiable" , "Sympathetic" , "Pleasant -- genial" .)

I've seen this clue in the Sydney Morning Herald.
