The SG-230 seems to handle 100 watts just fine. It is
interesting to listen to an autotuner tune up a transmitter
equipped with foldback. Clickidy-Click, the signal goes from
S5 to S9. If the foldback circuitry failed, then there would
probably be a bad outcome.

Assuming foldback and reflected power not invading the remote
tuner, I don't see why any harm would be done. 'Course, I'm
suffering from macular degeneration.
