What's the 'quietest' receiver you've ever owned or used?
 

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.

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.

I've got one that doesn't work, does that count? No sound at all...

Seriously, though, I think the radio with the quietest noise floor is my
Zenith Trans-Oceanic 3000-1. It has very little audio until you tune across
a station. It's not unusual to blast yourself out because you turn up the
audio, thinking there should be lots of static.
