[Elecraft] [w2/K3] High SWR

[Donald Thompson]

Hi Geoff,
The W2 is powered from shack supply, Astron RS-20.  The MJF-259 from fresh   AA batteries.  K3 also on shack supply. K2 on internal battery.
The coax is connected to the balun at end of ladder line as supplied by W8AMZ, nothing else. 
The coax is passed thru a polyphaser at the lightning control panel outside shack, just outside the wall.
The w2 coupler is inside shack at coax entrance.  The radio is grounded with 1/2 in copper strap to lightning panel.
There are no chokes.
The SWR does not vary with hand on line anywhere inside shack on any band.
Thanks
