I believe the answer is:

chapter one

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

'start writing' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'trace phone transmission somewhere' is the wordplay.
'trace phone' anagrams to 'CHAPTER ONE'.
Though, I am unsure how this is indicated.

'to' is the link.
