[Elecraft] KX3 for SWLs?

[Chris Chien]

Using the PREAMP increases both the signal and noise at the same time.
It works well with a 20dB gain active loop antenna, but it still not
completely blowing the Grundig away. I might want to test it later with a
full size dipole.
Though the little G3 is not at all in the same class as KX3, but it is
still comparable in terms of shortwave listening.
