Hmm ... Above 49 meters an AlexLoop with the KX3
should work very well for SWBC.

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.

You could use an "active antenna" (amplified) with the KX3 -- just don't
transmit into it. The Grundig probably has the equivalent of an active
antenna amplifier built in.

I agree. I used a short whip simply to see if the KX3 is suitable for
portable SWLs.
In this case, I would say a short whip doesn't make KX3 a descent
shortwave receiver.

The Grudig has more gain because it is designed to be used with a short
whip. The KX3 is built for high dynamic range with full-size antennas, so
it will perform better with a long wire, dipole, vertical, etc., cut for
the band in use.
But if you have no choice but to use a short whip with the KX3
sometimes, you can increase the PREAMP menu setting to 30 dB (a per-band
setting).
