> He's talking (broadly) about something that both GPS and CDMA (and it's
children) do and thats recover signals below the noise floor.  Some of that
tech came out of the radio astronomy field which is the way black holes are
researched for the most part.  He's trying to make the claim for pure
research funding benefiting the consumer domain.  Doesn't have any "ham"
reference.  Lets also not forget there were "mobile" phones prior to the
cell era (but were probably closer in tech to a 2M auto-patch) and were
hugely expensive.
