[Elecraft] Funky antenna issue

[Don Wilhelm]

John,

You have an open path for the DC power - somewhere - and the antenna is
providing the required grounding path in one manner or another.

Since you have just installed the KAT1, the first thing to do is remove it
(don't forget to put in the jumper) and see if behavior is restored to
normal.  Then let us know yea or nah so we can determine the next step.

73,
