AMSAT News Service Bulletin 116.03 From AMSAT HQ
SILVER SPRING, MD. April 25, 2004
To All RADIO AMATEURS
BID: $ANS-116.03
Ray Soifer, W2RS reports that the procedures recently adopted by IARU Region
1 (Europe, Russia, Middle East and Africa) for reporting illegal non-amateur
interference to amateur satellite uplinks have now also been adopted in IARU
Region 2 (the Western Hemisphere), with only one small difference: because
IARU Region 2 does not have a regional satellite coordinator as does IARU
Region 1, we in Region 2 are asking those reporting such interference, and
their national societies, to send copies of their reports to the IARU
Satellite Advisor (ZS6AKV) and his Advisory Panel at satcoord@iaru.org.
Steps to identify and help eliminate such interference will be coordinated
among all three IARU Regions, at two levels: through the Satellite Advisor
and Advisory Panel, and also through the worldwide IARU Monitoring Service
organization, including MS Coordinator Bob Knowles, ZL1BAD, and his three
regional coordinators.
To : All IARU Member Societies in Region 2
I would like to inform you of a small change in the operation
of the IARU Region 2 Monitoring System, concerning intrusions
in the VHF/UHF Amateur bands and interference to Amateur
Satellites.
Historically, the Monitoring System has concentrated on the HF
bands, and has ignored the VHF and UHF bands where interference
has tended to be local and almost always within national
borders. Now, however, when intruders use the same VHF and UHF
frequencies already used by Amateur Satellite uplinks, the
resulting interference crosses many borders.
Several years ago in cooperation with AMSAT-NA, the Region 2
Monitoring System developed a simple, informal arrangement to
deal successfully with a particular instance of this problem.
Further, at the 2001 Region 2 conference in Guatemala, a
recommendation was passed (Annex C to the Report of Committee
"C", TG-P-04), calling attention to the growing problem of
intruders in the VHF and UHF bands. Most recently, the IARU
Region 1 Monitoring System has undertaken to include VHF/UHF
intruder problems in their regular activities.
To respond better to this problem in Region 2, the general
procedures of the Monitoring System will be broadened
slightly, resulting in three small changes :
1. Member societies in Region 2 are encouraged to include the
VHF/UHF bands in their monitoring system activities, especially
but not only the Amateur Satellite uplink sub-bands;
2. Societies are encouraged to include reports of intruders in
the VHF/UHF bands in their monthly reports to the IARU Region 2
Monitoring System Coordinator; and
3. When monitors or coordinators report intrusions involving
satellites, they should also send a copy of their report to the
IARU Amateur Satellite Advisor, ZS6AKV.
These changes can be seen in context in the web pages at

I hope that your organization will support and promote these
changes. Thank you and I wish you success in all of your work.
