Worlds Best Noise Floor
- Thread starter C2
- Start date
Measured how? In degrees Kelvin?
I hear the receivers used for radio astronomy at Arecibo have cryogenically-cooled front ends, and that they get down to single digits in that department.
As for a communications receiver, no.
Haven't been to too many places quiet enough to really matter to me. Gotta get away from town a ways before the sky gets really dark at night. Radio seems to be the same way. Noise levels in town tend to be high.

C2 said:the worlds best noise floor is -167 dBm.
It's on my bench right now.
I assume that dbm, in this case, refers to "Dirt Bags/Minute"
