Radio reception problem which never goes away (6)
I believe the answer is:
static
'radio reception' is the definition.
'static' can be an answer for 'reception' (thesaurus). I am unsure of the 'radio' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for static that I've seen before include "Not in physical motion" , "Lacking movement or action" , "Lacking change" , "Unmoving like kind of electricity" , "Stationary" .)
