  Ross,

Who knows what the L and C values are that are in your T1 until you do a
TUNE.  The incication of a low SWR when the T1 is in bypass indicates
that there is residual reactance when in non-bypass.  Doing a TUNE
should straighten things out.  The settings are remembered by band, so
do a TUNE on each band.
