<P>Important: both <EM>freq</EM> and <EM>on</EM> are exactly the same and can be
used interchangeably - most persons use <EM>on</EM> (less typing.)</P>
<P>For range, you can specify a frequency like 7040, a range of frequencies like
0/30000 ( the whole HF band) or use any of the "band" or "region" names defined
in the show/bands command.</P>
