Band has hit with antiquated communication equipment (6,3)

'band' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'hit with antiquated communication equipment' is the wordplay.
'hit' becomes 'box' (boxing is a kind of hitting).
'with' is a charade indicator (letters next to each other).
'antiquated communication equipment' becomes 'police' (I can't explain this - if you can you should believe this answer much more).
'box' put after 'police' is 'POLICE BOX'.

'has' is the link.

Can you help me to learn more?
