Sure, and in this case the original indicated input SWR was more like 1.5:1
than 1:1, hence the length of feedline mattered.  I'd still like to know
why a higher indicated SWR (on the TS-930) translated to higher output,
plate current and grid current on that one band, but for now it's enough
just to have things back behaving normally...
