[Elecraft] K2 - Unstable power output on 40m (digital modes)

[Brian - N5BCN]

Don,

Yes, things settle down with a dummy load, so it looks like I'm dealing with
RF feedback.

Per the original post, I'm using an Elecraft BL2 balun at the
coax/ladderline junction.  Shouldn't this act as the common mode choke that
you suggest or are you suggesting to place a common mode choke in addition
to the balun?

Interesting idea regarding the KPA100 latest version since 40m is the
troublesome band.  I purchased the KPA100 around 2011-2012, so I would think
it has the latest hardware but I'll double check when I get a chance.
