Between "gr_simple_squelch_cc" and "gr_pwr_squelch_cc"? Besides that
the latter inherits from a base class, and is generally a little more
robust (e.g. allowing for ramping on and off), I don't see any
significant differences between them. Thus I'm wondering if both are
used by folks, and if not, and they really are programmatically
equivalent, then can the former be removed? - MLD
