WIA volunteers find 5000 intruders
Wireless Institute of Australia observers looking for intruders on the
‘Primary’ frequencies of the Amateur Service on high frequency bands
in 2016 found more than 5,000 intrusions - FIVE THOUSAND !
These were collated and sent to the spectrum regulatory agency in IARU
member countries.
A resulting clamp down on the Indonesian ‘village radio’ stations was
occurring with the government regulator progressively removing
offenders.
The WIA reports intruders to the Australian Communications and Media
Authority, but due to the itinerant nature of some intruders this can
prolong the process for their removal.
Unfortunately, some authorities seem to ignore requests for the
removal of interfering services.
Among the observers is the very active John Kirk VK4TJ with monthly reports.
Individual volunteers have also left frequent reports sent via the WIA
website electronic lodgement system, in particular ALARA's Lyn VK4SWE
and Col VK4CC.
An increasing number of digital emissions are intruding, and the use
of Software Defined Receivers have identified non-amateur digital
systems that are frequency hopping. The Manly-Warringah Amateur Radio
Society of New South Wales has a five-band SDR receiver system that
greatly assists in monitoring activities.
Perhaps other clubs could help too?
For the WIA monitoring system to work volunteers are required.

The latest The IARU Region 1 Monitoring System newsletter reports a
STANAG-4285 signal in the 40m amateur radio band probably from the
Falkland Islands
They say the signal on 7101.8 kHz was strong in South America, but
rather weak in Europe. STANAG-4285 is typically, but not exclusively,
used by the military.
