That is exactly the functionality of the power_squelch block :)

Well, yours :)

I'm still not totally clear on what kind of *signal* you want to
produce, or whether you describe a temporal *behaviour* of your system.
What aspect of your implementation are you currently working on? The
Energy Detector/pass-through functionality?
Best regards,
Marcus
PS: I think you've described your thing pretty well, I'm just not
getting it, sorry.
I think at this point, a drawing with a few annotations of what your
system should do would do wonders, because then we'd have something
clear to refer to when discussing!
