Hi all,
?
the Elecraft K3 is reputed one of the best commercial transceivers
available to the amateur radio. Well, as you may read the following mail I
received a couple of days ago, there is still something to squeeze out of it.

A Modified K3 in the 2013 ARRL DX Contest
?
Giancarlo,

I did a test in the 2013 ARRL DX contest. At LX7I we had 2 x K3 on the same
antenna, locked out with the Acom 2S1 box. One of the K3 had the I7SWX K3 2T
H-Mode Mixer installed, the other K3 was in original state.

I did not tell about the difference to anybody but after the contest one of the
operators told me I should check the K3 because there were weak stations that
he could hear with one K3 (the modified one) and could not hear them with the
other K (the original K3).

LX7I has large/high antennas, see www.lx2a.com

So
yes your mixer gives a slight and sometimes decisive advantage, congrats.
