The input SWR at 160m is below 1.5:1 from 1800 to 1925 khz, then rises rapidly to >3:1 at 200 khz.

Similarly, at 80m it's below 1.5:1 from 3600 to 3880 khz then rises to 2.2:1 at 4000 khz.

Those are at what seem to be optimum settings of the trimmers for each of those bands.

Wondering if others have similar experience, and have succeeded in "flattening the curve".

73, John
