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.
