Hi, Tom:

I have a commercial dummy load that reportedly cost $1,300 and is certified 
to be better than plus or minus 00.5 percent accurate.  With that load, my 
LDG-2 shows 1.2 to 1 standing wave while my ICOM 746Pro reports 1 to 1.  I 
used 3 different 99-13 patch cables. Don't think that helps other than 
perhaps to provide you another reference to ponder.
