<DIV>USA: 5MHz for EMCOMM, not Ragchew, not Contest/DX<BR>--an article by Bonnie
Crystal KQ6XA<BR>=== <BR><BR>The 60 meter ham band has quite different
<BR>operating privileges in various countries <BR>of the world. The frequencies,
rules, purpose, <BR>regulations, operating procedures, and levels of
<BR>priority are all different in each country. <BR><BR>In USA, the 5MHz
channels for ham radio were <BR>specifically requested, justified, and approved
<BR>primarily for Emergency and Disaster Communications. <BR>The stated
justification is the need for NVIS and <BR>regional disaster response
communications to fill in <BR>the propagation gap between 40 meters and 80
meters. <BR>The process of the Amateur Radio Service gaining <BR>access to these
5MHz frequencies was long and exacting. <BR><BR>Recently, due to another
multi-year process of proposal <BR>and rulemaking, FCC increased the privileges
slightly <BR>for hams on 5MHz. However, the FCC put even tighter <BR>technical
restrictions on 5MHz operation than on any <BR>other ham bands. 60 meters is not
a normal ham band.<BR><BR>In this new ruling, FCC re-affirmed and clearly
spelled <BR>out major restrictions for hams on 5MHz. Hams are <BR>secondary
users (or less) and the Primary users of the <BR>5MHz channels must not be
interfered with in any way.<BR><BR>Non-interference with a Primary user isn't
just a matter of <BR>stopping transmitting if you are asked to. It can also
<BR>mean refraining from transmitting, if there is *any chance* <BR>that you
might be preventing a Primary user from utilizing <BR>or starting communications
on the channel, even if you are not <BR>asked specifically. The only way we can
hope to fulfill our <BR>requirement for non-interference, is to use very short
<BR>transmissions and listen/watch carefully between transmissions. <BR><BR>What
are some common amateur radio operating practices that <BR>may not be suitable
for 5MHz 60 meter band operation in USA? <BR><BR>1. Calling CQ DX.<BR>2. Long
CQs. <BR>3. Longwinded ragchews.<BR>4. Calling in pile-ups.<BR>5. High power
transmissions. <BR>6. Contesting.<BR>7. Sending a 'brag file' on PSK31
<BR><BR>In order to be ready for Emergency/Disaster Communications, <BR>hams
need to have good familiarity with the band and have <BR>equipment capable of
operating 5MHz. Hams can only do this <BR>by participating in active operating
on the 5MHz band. <BR>Somehow, we need to achieve a balance between a good
<BR>level of activity and the requirement for non-interference.<BR>Finding this
balance may be difficult, but for the most <BR>part, hams are quite adept at
good operating habits. <BR><BR>Every ham operator transmitting on 5MHz must pay
<BR>special attention to the different operating methods <BR>and procedures that
this unique authorization requires. <BR><BR>There are proposals in the works to
create an <BR>international ITU allocation of a 60 meter Amateur Radio
<BR>Service band with Secondary status. <BR><BR>If hams in USA are found to be
operating in ways that <BR>disregard the spirit of the requested, justified, and
<BR>approved reasons for which we obtained 5MHz privileges, <BR>then it may be
extremely difficult to ever get FCC <BR>support for increased spectrum.
