[160m] Selecting frequencies for SSB on 160m

[Topics related to 160 Meters Topband]

Some friends and I are planning a
portable operation on 160m using a
quadcopter to lift a quarter-wave
ground plane antenna.  I'm the
senior ham in this group (licensed
since 1976) but I have rarely worked
SSB on MF or HF (preferring, as I do,
CW and digital).  I've never worked
160m at all.  I want to do this
right, so I have some questions,
submitted in the spirit of "the only
dumb question is the one you don't
ask."

Question 1:  What frequencies are
appropriate for SSB QSOs on 160?

Question 2:  I believe there is a
DX frequency or DX window on 160.
What is the DX frequency/window?

Question 3: Would it be OK to call
"CQ DX" on/in the DX frequency/window?

Thanks for your kind patience with my
seemingly newbie questions.

If there is any interest, I'll post
again once we select a date, and let
everyone know what time we plan to
be operating.  We expect to have ~15
minute windows until the quadcopter
battery is depleted.
