[Kenwood] Kenwood TS570 SWR circuit issue

[JOHN GEIGER]

Picked up a used TS570SG recently.  It is a nice radio overall.  However, the SWR circuit doesn't seem to be working correctly.  It never shows higher than a 1.5 SWR, even with no load connected.  And it doesn't agree with an external meter I  have.  Consequently the SWR/Power foldback circuit never really gets activated. I tried a full reset on it and it still does the same thing. 

 

Ideas?  Anyone seen this before?
