[Elecraft] Z match versus KAT100

[W3FPR - Don Wilhelm]

David,

There is a good chance that you are not imagining things.  Your tuner is
likely a link coupled design which isolates the transceiver side from any
circulating currents on the antenna side.  A balun does not provide the same
isolation.  Antenna currents can be induced from BC stations, wind static,
rain static, etc. as well as the desired signals.
