I have noticed similar readings. Could be difference in where each one is
in the coax system. I've found the tw1 not to be very accurate in power
and swr. It is close and relative, but that is all most of this stuff is
anyhow. Somewhere I've got a noise bridge which is really the way to find
the dip or resonant point.; Speaking of dip, a grid dip meeter would do
that as well.
