[Elecraft] kx3 receiver versus K3s receiver

[Erik Basilier]

Both the kx3 and the K3 are excellent. The KX3 may sound slightly more
natural, but overall I prefer the K3 because of better ergonomics and some
aspects of performance. Recently I got interested in SO2R and added a
KXPA100 to my KX3 for use as the second radio. In side by side comparison it
became clear that the KX3 is much more vulnerable to interference than is
the K3. With my antennas close together, the KX3 was marginally useable
receiving on 40 while the K3 transmitted on higher bands, but totally
unuseable with the K3 on 40 and the KX3 on a higher band. There are a lot of
variables involved, but I got the same result with a portable setup at a
different location. Most people will never run two rigs set up close
together with antennas close together, but I plan to buy another K3 and sell
the KXPA100. The KX3 is still wonderful for light weight portable operation.
