However, a control operator does not have to be
present at the physical location of the HF
transceiver.  They only have to be present at the VHF
control station which could be located some distance
from the HF station.  And this is what I mean when I
say be careful.  If all the information for
controlling an HF station is floating around, it's
possible for some random person to try and use the HF
station at some other location.  So the word of
caution is about allowing control information to be
published which could allow an outsider to take
control of the HF system without authorization.

The whole point of Sky Command was to operate the HF
station without having to sit in front of it or have
anyone there.  This part is still legal because the
remote VHF station is in control (and all the links ID
themselves, too).  But it doesn't prevent someone from
grabbing control and that's the part to prevent.  So
having a remote control HF station may be great
especially for emergencies, but I certainly wouldn't
be broadcasting that capability in general over APRS
or anywhere.
