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?

the DX-394 is very quiet yet pretty sensitive. after I have modded one it is
a very nice receiver !

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.

Harris RF-550 with AFC and coherent AGC on.

Very easy on the ears.

The quietest receiver I ever owned was a Scott RX-200 (same radio as the
Grundig S-350 or Tecsun BCL-2000) that I bought off of E-Bay. It was very
quiet as it was DOA.

The WinRadio G313i by far. Noise floor -138 dBm and the continuously
adjustable IF filter let's you adjust the IF bandwidth to precisely
match the bandwidth of the signal. No other receiver comes close.

Agree - 313i is the quietest by far.

The Collins should win this contest hands down. Nothing, to my knowledge,
ever had a lower noise floor. The story is that it was only limited by the
Galactic background noise level. You can't do any better than that.

They're pretty amazing receivers. Now if they only tuned like a SP-600
