Receiver set to knot tie on the outside of jeans (10)
I believe the answer is:
television
'receiver set' is the definition.
'television' can be an answer for 'set' (television is a kind of set). I'm not certain of the 'receiver' bit.
'knot tie on the outside of jeans' is the wordplay.
'knot tie' becomes 'ion' (I can't justify this - if you can you should believe this answer much more).
'on' means one lot of letters go next to another.
'outside of' says to hollow out the word (remove centre letters) (I've seen 'outside' mean this).
'jeans' becomes 'levis' (Levi's is a brand of jeans).
'the' with its middle removed is 'te'.
'te'+'levis'='televis'
'ion' put after 'televis' is 'TELEVISION'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for television that I've seen before include "Gogglebox" , "Tube" , "box set" .)
