What you might consider doing is to put loading loops on each side
of your feed point. You can can set the antenna up for CW with
the loops, then short them out for Phone. You can use DC switching
up your coax with RF choke isolation and you be at the low voltage
point. It would be a form of linear loading, which works fairly well
for in-band QSYing of an antenna, as not much loading would be

Excuse the poor graphics:
