[TenTec] Orion II

[Richards]

THANKS !!    That sounds much more useful than my Omni VII band
scope display - which is handy enough on its own.   There are some
questions dealing with this on the Extra Exam, but my Gordon West
audio tutorial glosses over it without much explanation.   I will have to
re-read the ARRL book that actually tries to explain it, and not just
tell me the answer.   I don't think stuff sinks in too deep if I don't
actually understand the why of it.  I don't just memorize the answer,
although it is tempting.

Given all that, I can see why some guys might miss it !

Happy Trails.
