I've been following this saga for a while now, and I note no one seems
nonplused by the statement above. For as much that has been unsaid,
there must be a flood of presumptions that flowed from this detail.

It would have been much better off for me to state that, "Say I have a signal
generator that I know happens to provide an SNR of 60dB." I knew that
background radition temperatures were high, but not that even the quietest
parts of the spectrum are 4,000K!
