Dear Kevin,

Yes and yes. It is usual to leave the squelch open. Although during most
of the pass the signal would be enough to open your squelch if you leave
it in the lowest setting, really the squelch setting is the last thing
you should be worrying about.

Using headphones to avoid feedback is a must. It also helps you a little
to pick signals out of the noise in bad conditions.
