[Elecraft] KX3 for SWLs?

[Chris Chien]

Both the bandwidth and speaker have been taken into consideration. With a
short passive whip, the KX3 is far behind the Grundig, because even strong
station is barely heard from KX3.
However, an active antenna makes the KX3 much better, but still not
significantly better than the little Grundig.
In fact, this comparison is not a fair game for both rigs. The Grundig has
a built in amplifier to work with the telescopic antenna, while the KX3 is
not designed for that purpose. A safe conclusion would be that the KX3 is a
little deaf using short whips, and the Grundig is a descent shortwave
receiver too.
