Barry is in VK. If he operates from the middle of nowhere, local noise is
nonexistent and local activity is extremely sparse. It means you hear lots
of weak stations, most of which you have little chance of working unless you
have good antennas and run power. So preamp is a plus in receive but it

Barry,
Not disagreeing. I bought my K3, SN4043, in 2010. It has an
internal preamp (push PRE) which gives about 10-dB gain (I
think). A few years went by and Elecraft announced the PR6 external
"add-on" preamp to improve 10m and 6m receiver performance. They
kind of admitted the bare K3
Hi, Barry,
It's not the signals that determine whether you need a preamp, it's the noise
level. A receiver should have enough gain to put its internal noise floor below
the external, atmospheric noise floor, so that it doesn't become the limiting
factor in hearing weak signals close to the noise
