Platform where you see some hero’s trumpeted (7)

I believe the answer is:

rostrum

I'm a little stuck... Click here to teach me more about this clue!

'platform' is the definition.
(I know that rostrum is a type of platform)

'some hero's trumpeted' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ROSTRUM' is hidden in the letters of 'heros trumpeted'.

'where you see' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for rostrum that I've seen before include "At which one may conduct" , "Raised platform" , "Rum rots (anag)" , "stage" , "Platform for speaker" .)

I've seen this clue in The Times.
