Sound broadcast in Strathclyde town (3)
I believe the answer is:
ayr
'strathclyde town' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ayr that I've seen before include "Scots port on Firth of Clyde" , "Scots. town; sounds like song" , "Scottish resort" , "Scottish town sounds tuneful" , "Town in Strathclyde" .)
