> > > As another year draws to a close I am reminded of how much the
> > > Amateur Radio community owes to the dedicated volunteers who
> > > work with you in the IARU Monitoring System. It is easy to
> > > become discouraged in what seems to be a never-ending battle,
> > > particularly as we face a worldwide proliferation of unlicensed
> > > HF operations. Still, we should stop to consider what our bands
> > > would be like if there were no organized effort against
> > > intruders. For example, when you compare the level of out-of-
> > > band broadcasting in the fixed service bands to that in the
> > > amateur bands it is easy to see that our efforts do pay off.
> > > Even the unlicensed operators are more likely to operate outside
> > > our bands than inside; it has become such a problem for the
> > > maritime and aeronautical mobile services that the issue is on
> > > the agenda for WRC-03. It is unlikely that the conference will
> > > find a solution that is as effective for those services as the
> > > IARUMS has proved to be for the amateur service.
> > >
> > > As we enter the New Year, please know that your efforts and
> > > those of your volunteers are greatly appreciated by the IARU
> > > officers and the members of the Administrative Council. On

> > > NOTABLE INTRUDERS HEARD IN REGION 2
> > >
> > > The following intruders were most notable during December in Region 2:
> > >
> > > 80 m J3E,U Fishing vessels on 3650, 3793 and 3944 kHz,
> > > all USB.
> > > 14250.1 kHz A3E, N0N Radio Pyongyang, DPR Korea, shortwave broadcast.
> > > 14301 A3E, N0N Radio Majagual, Sincelejo, Colombia, harmonic
> > > from medium wave band.
> > > 10, 12 m AM, SSB CB types, truckers, and taxis using AM or USB
> > > or LSB.

> > > More fishing vessels have been reported using the 80 metre band in
> > > USB mode. On 3650 kHz stations in an Oriental language, possibly
> > > Japanese, have been heard again in eastern Canada, this time around
> > > 1200 UT. Spanish speaking stations, probably in the Gulf of
> > > California, have been using 3793 kHz during the 0300-0500 UT period.
> > > Also, 3944 kHz has been used by Spanish speaking stations, possibly
> > > Mexican fishing vessels in the Caribbean. One of the stations on
> > > 3944 had a 990 Hz "roger beep" with an echo effect on his
> > > transmissions, indicating possible "CB" activity rather than use of
> > > maritime mobile equipment. While interference from such stations can
> > > be annoying, Amateurs must remember that the 80 m band is shared with
> > > other services including the Mobile Service. The segment 3500-3750
> > > kHz is allocated to the Fixed and Mobile Services on a primary basis
> > > in Honduras, Mexico, Peru, and Venezuela, and the segment 3750-4000
> > > kHz is allocated to the Fixed and Mobile (except aeronautical)
> > > Services on a primary basis in Argentina, Bolivia, Chile, Ecuador,
> > > Paraguay, Peru, and Uruguay. In other words, in many countries of

> > >
> > > Radio Pyongyang, North Korea, continues to produce a significant
> > > harmonic on about 14250 kHz that is heard in both North and South
> > > America. Two characteristics of this signal are its slightly
> > > variable frequency (over a range of about 50 hertz) and the weak
> > > audio hum that is sometimes detected (an audio spectrum analyser
> > > helps) at 46-47 hertz and its second harmonic at 92-94 hertz. Radio
> > > Pyongyang is the source of a number of harmonics and spuriosities
> > > that invade the Amateur bands, besides their broadcast on 3560 kHz
> > > (which frequency is not allocated to the Broadcasting Service). All
> > > informal efforts to have these signals removed have failed, so
> > > "Arasu" Manohar, VU2UR, IARU MS Co-ordinator in Region 3, has sent
> > > two detailed formal complaints to the Secretary, IARU Region 3, in an
> > > attempt to get the message more forcefully carried to the
> > > administration in North Korea.
> > >
> > > The harmonic from Radio Majagual, HJQX, located at Sincelejo, Sucre
> > > province, Colombia, is now so weak on 14301 kHz (variable) that
> > > Brennan Price, N4QX, ARRL MS Co-ordinator, no longer receives reports
> > > of it interfering with the several Amateur nets using 14300 kHz USB.
> > > There is still a faint, slowly wandering carrier detectable in

> > > with Liga Colombiana de Radioaficionados (LCRA) for his work (more

> > > Amateur bands when propagation conditions permitted. Two ways to
> > > solve this problem are enforcement of the frequency allocations by
> > > national administrations and education of the users of these illegal
> > > radios about 'responsible use of the spectrum'. A third method is
> > > pointed out by Brennan Price, N4QX, ARRL MS Co-ordinator :
> > > "I monitored *zero* intrusions in the 10 metre digital segment
> > > while the ARRL RTTY Roundup was on the air. This reaffirms my

> > > weapons in our efforts on 10 metres. Personally, my Amateur
> > > Radio New Year's Resolution is to be on the air more often -
> > > transient intruders will be less likely to use a frequency that
