Amateur band man? (5,3)
I believe the answer is:
radio ham
'amateur band man?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'amateur band man?' is the wordplay.
'amateur band' becomes 'radio' (I am not sure about this - if you are sure you should believe this answer much more).
'man?' becomes 'Ham'.
'radio'+'ham'='RADIO HAM'
Can you help me to learn more?
(Other definitions for radio ham that I've seen before include "not a professional communicator" , "fan with transmitter" , "hobbyist on the waves" , "Bad broadcasting actor" , "Amateur broadcaster" .)
