[Elecraft] K2 Jumping SWR

[Thomas Beltran]

I've been using my K2 at home to become more familiar with it.  Previously, I used it primarily while camping.  While camping, I noticed that the KAT100 will show changes in the SWR, sometimes moving up to over 2:1.  When I would press the "Tune" button, there would be no adjustment (because it was correctly tuned).  Now at home, it does the same thing.  I'm using a SteppIR 3 element beam.  Before I try to dig out my dummy load, I was wondering whether this was something others have experienced.  Tom W6EIJ
