This info is from their report which is published several times a year. Hopefully this will explain some of the intruders we hear on our bands.
CODAR on 14 MHz – no change as usual
The CODAR ocean surface radar on 14075 - 14125 kHz is still active from North-East India daily, all day.
Radio Tehran with spurious on 21 MHz – still problems in December
Radio Tehran on 21500 kHz produced spurious signals on 21445, 21390, 21335, 21280, 21225, 21170, 21115, 21060 and 21005 kHz. (55 kHz increments) Every morning at about 0800 UTC. The German BNetzA and the Swiss BAKOM filed complaints.
KOL Israel – Fake or Mistake?
A BC transmission from KOL Israel was observed on 14000.0 A3E on Dec. 16th and 17th. The bearings showed the area of Israel. The announcements said “KOL Israel”. HB9CET noticed that the bandwidth was 6 kHz instead of 9 kHz (usual BC bandwidth). A mistuned transmitter could have been the source. It was also possible that someone tried to give a bad name to KOL Israel by transmitting the BC program using a HAM-transceiver.
Mysterious signals on 7000, 14000 and 21000 kHz from Central China - no change
The mysterious multitone signals, often as A3E and 6 kHz wide ang the chirpy signals on 21000 were active daily.. The purpose is still unknown. Perhaps a new kind of communication??? The Dutch, Swiss, UK, Austrian and German PTTs were informed.
6. Russian daily taxi business on 21 MHz Taxi net from Kaluga on 21404.2 kHz in FM. The Austrian, Dutch, German and Swiss PTTs were informed. PB2T, Hans, filed a complaint to the Russian Amateur Society. This is another example for excellent cooperation. The daily violations of our 10 m-band by CIS taxis are going on as usual.
Russian harmony
We found several harmonic emissions from Russian teleprinters on 21 MHz, sometimes even the 4th of a lower frequency. The Radio-Amateurs do not like such kinds of harmony on their bands. It is easy to detect the harmonics. They often have a shift of 2 kHz. For example: Calculation: 21400 kHz : 4 = 5350 kHz. The shift on 5350 kHz is 500 Hz. HB9CET and me checked the fundamental transmissions. We saw, that our calculations were correct. The Russian military is often using F1B (teleprinters) with 50 and 75 Bd and 200, 250, 500 and sometimes 1000 Hz shift.
The 1st harmonic from 7018 (F1B - REA4 – Russian Airforce Moscow) is causing strong interference on 14036 kHz. Shift on 7018 = 1000 Hz, shift on 14036 = 2000 Hz. The signal has a very bad quality and is active daily,all day.
From our fellow hams in Portugal...
OTH radars still interfere and are like a plague in a meadow. Almost all Bands are interfered and sometimes, inside WARC segments, the BW of signals are occupying a great part of the Band with only one transmission. It seems some Northern part of Africa operators are doing big 15m SSB QRM on CW segment activities. We shall take it into consideration and monitoring will be made in the future with better propagation conditions.
There are many discussions and pricking on 7070 kHz, Lower Sideband, between Italian and Portuguese Hams because of pretense rights over that frequency. It’s an old problem with bad attitudes like music, jamming and offenses. We hope it will finish in the near future for the best image of Amateur Radio and the Countries involved. 10m Band is quite calm at moment, but at 1700Z to 1900Z (Trans-Equatorial), we have detected many AM and FM operations from Brazil between 28000kHz and 28500kHz daily. Some Portuguese and Spanish fishermen are talking sometimes on these frequencies too.
There are (buoys ?) transmitting F1B burst group on 28025.0kHz (+/-) with 51 Bd, 300 Hz shift and 28100kHz, F1B, 51 Bd, 320 Hz shift or 29525.0kHz, transmitting in F1B with 81.9 Bd, 140 Hz shift. ICP-Anacom, the Portuguese Authority for Telecomm is very active and collaborating with us to detect and stop those intrusions on our 10m Band.
It is with great pleasure we may report that a giant operation was executed by our National Telecom Authority – ICP Anacom with our Maritime Police during tree days, where were verified 30 fishing boats in Algarve and arrested several Tx/Rx equipments not authorized for maritime communications and illegally used on Amateur Bands. Five boats were arrested because they had no valid telecom certification but had equipments working over not permitted frequencies for the maritime traffic.
The big operation has been carried on December 11, 12 and 13 in Portimão, Albufeira, Lagos and Sagres in Algarve, and our Anacom is decided to stop the abuse, interference and infringes over several communications services, namely on Amateur Radiocommunications Bands, by the clearly illegally installed and operated stations inboard of fishing vessels. After all reports and demerges made, it's a fair very good year-ending for our IARU-R1 Ms in Portugal.
Worldwide cooperation and results in 2012
IARUM
One of our highlights in 2012 was disabling Radio Free Asia on 21450 kHz. DK2OM (Region 1) got an alert from ZL1GWE (John - Region 3) concerning “Radio Free Asia” on 21450 kHz. Wolf informed K1ZZ (Dave – Region 2). Dave could solve the problems in Region 3 by his special connections. New intruders like the mysterious signals from China or OTH radars appeared and caused strong interference on our exclusive bands. The Russian military preferred our 7 MHz-band for digital traffic daily and often with bad quality. Chinese radars on 7 MHz were even audible in Europe, Japan, Australia and California. Many problems will wait for us in 2013 (as usual...).

11. Introduction of HB9CET First my very best wishes, best of health and prosperity in 2013
Thank you most sincerely for your trust and confidence in me as new Vice-Coordinator IARUMS R1 and successor of Uli, DJ9KR. I will proudly fulfill this task, being firmly convinced that our monitoring job remains very important and indispensable also in the future.
My specialism are digital emissions and I'm broadly equipped with several modernest analysis
tools from Wavecom. Running a remote site with a Perseus SDR and several antennas at a calm location; soon extended by a Winradio G33DDC SDR rx. At home I use KX-3, IC-7600 and IC-8500. Hope that I may see as many as possible of you in Friedrichshafen 2013 by the next Ham-Radio 2013. Will be there all 3 days.
