I'm not using any core, just bring the two of them to a box that lets me
pick each one separately or just parallels them directly... bring that back
to the shack and go through an mt-3000 to shift the min swr from cw to ssb
and even out between singles and both, and no problem here. The little
mismatch on the hardline to the shack doesn't bother me at 40m.
