[Elecraft] SWR on 40 meters

[Mike Wetzel]

All of a sudden (I think) the SWR on one of my K3's (#1) is showing 1.5 to 1
into a dummy load on 40 meters only.  All other bands the K3 (#1) shows 1 to
1, my other K3 (#2) shows 1 to 1 on all bands using the same dummy load and
same piece of coax.  I also noticed that on one antenna where the SWR is 2
to 1 on a bridge (and on K3 (#2)) it shows 1 to 1 on the K3 (#1).  I guess
this really doesn't affect anything (maybe power roll back).  

 

K3 (#1) has no ATU but new synt boards.  K3 (#2) has an ATU (in bypass mode)
but the older synt boards.

 

Any ideas and thanks,
