How long after first impact should it take for the ELT to kick out a
call on frequency?

I assume pretty quickly, but if you're referring to the Fossett crash,
note that the NTSB report says the ELT was destroyed on impact.

I didn't catch the "on impact" only that it was destroyed. I guess they
judged that no signal meant destroyed on strike, must have been a hell
of a crash reading through the report.

Oops, you're right, I must have subconsciously assumed the "on impact".
Seems probable that the impact is what destroyed it, but it doesn't say
that, and it certainly could have happened later (e.g. in the fire). My
apologies.
