I started thinking about this tonight. I was tuning around with a Lowe
HF-150, comparing it with some other receivers, and was struck by how
quiet the 150 is--and by what an advantage this is when it comes to
resolving weak AM signals.
So, just out of curiosity, what's the quietest receiver you've used
and/or owned?
I too like my 150, but the current receiver I am building- loosley based on
a W7ZOI design is quieter, probably due to the gain distribution and the
fact that Wes designed the AGC such that it does not kick in until
about -90dBmV; unlike some of today's radios where you can actually see band
noise on the S meter.
Still under construction, with a 1980's theme:

The AM detector is an NE602 used in a squaring circuit - wonderful A.M.
recovery.
