Keith is quite right.
All receivers generate internal noise in their amplifiers. The goal is to
make sure this internal noise does not compete with the received signal so
the only thing that limits the ability to hear weak signals is the
unavoidable atmospheric or "antenna noise".

Doug, the preamp does not discriminate between signal and noise. It does not

ANY variable-D mic will work very well with a K3. The RE27 is a
variable-D mic and a variation on the RE20 that uses a neodymium
