The repeated appeals for organizing Monitoring Systems in every National Society of the Region, is showing results. RAST – Thailand and HARTS – Hong Kong are the latest Societies to join us. HARTS have nominated their Monitoring Systems Coordinator. He is OM Keiren VR2BXM, whio is expected to be feeding information of interest from his area. We look forward to RAST nomination of a suitable candidate.
This month also the picture points to the various harmonics, spurious and fundamntal Broadcasting channels used by Radio Pyongyang, DPR-Korea; Indonesian and Chinese intrusions affected Australia and New Zealand has “Havana Gurgle” and the Sea State radar-CODAR and many data stations on various amateur frequencies.
Continuing the topic of long range cordless telephone QRM in India, further reports received are reproduced for general reference.
2002
December 2002
This month, I digress from HF intrusions and go to the topic of VHF QRM, not touched so far in the editorial. While the situation of VHF QRM by Long Distance Cordless Telephones of Chinese Make, is still bad all over the different cities in India, a typical case from a city like Chennai, that is Madras, is open for the authorities to see and take the necessary action. If the amateurs in all the Indian cities, join together and produce such lists, identify and educate people in dissuading the use of such equipment, it is yeoman service to amateur fraternity.
I am reproducing the list of frequencies of Long distance Cordless Telephone QRM, as carefully monitored and submitted by the Madras Amateurs in a group, namely: VU3VTK OM Ganesh, VU2DPN OM Dheepan, VU2SBB OM Sambasivam, VU3USI OM Christy and VU2ZNS OM Swamy. This group has formed clear aims:
November 2002
OM Ronald Roden G4GKO/4X8RR, the Regional Coordinator of Region 1 has retired. His numerous contacts with other Organisations, the friendly guidance he was giving to all new comers, the tact of his handling cases of intrusions, his subtle humour and the innumerable other helping qualities, have been a strong source of inspiration to all the monitoring system coordinators. We wish him and his XYL, a very good retired life from this field of fighting against the intrusions into amateur radio frequencies.
The new comer taking his place to guide Region 1, through, is OM Hani Raad OD5TE of Beirut, Lebanon. He is an Electrical Engineer with over 20 years of experience in amateur radio. We wish the new incumbent, all the best in his new chair, and offer our cooperation at all times.
The fundamental on 3560 kHz and the other spurious products of Radio Pyongyang, DPR-Korea, on other frequency bands, are being heard even now and the Havana Gurgle on 18090 kHz has almost become a marker on the 17 mb for stations down-under. The results that might have come from the complaints that have been lodged in the specified proforma to IARU R3 HQ, are NOT visible in any lessening of the spurious emissions from DPR-Korea.
October 2002
This month also, we have innumerable reports on Indonesians, the data stations and the regular Havana gurgle from Cuba, CODAR sea state Radar, the several multi channel data stations, the usual fundamental and the several harmonics/spurious products from radio Pyongyang are continuing unabated. Unless, all possible pressure is brought on the known intruders, the condition continues to remain bad and may tend to worsen if we fail to complain and follow-up with reminders.
This months newsletter carries the three monthly reports from JARL, which were long pending and the readers can assimilate the statistics from the JA area.
In the Newsletter of IARU Region 2, of October 2002, the Regional Monitoring systems Coordinator OM Martin Potter, VE3OAT, has brought out in the most clear and lucid style, the need for a Monitoring system in every National Society. I want to share it with all of you, as it is very badly required immediately in many of the National Societies of Region 3.
September 2002
The Indonesian non-amateur activity being so much on the 40, 30,20 metre bands and the inaction of the Government concerned, is indeed causing a serious concern. The matter is so often reported that we feel hurt to repeat again and again.
In addition to these non-amateurs, there is a definite increase in the number of frequencies used by the fishing trawlers on the high seas, with their amateur radio equipment, instead of the Marine communication equipment, which they are supposed to have. Sri Lankan and Indian boats are often heard using many of our frequencies. The Australian reports indicate that Chinese boats are like wise causing concern. The presence of many data stations with multi channel high speed data traffic with the latest modes of communications are another cause of our worries.
Long range cordless telephone users are continuing caring none for the interference they are causing to other services.
August 2002
This Region has the maximum reports covering Indonesian non amateurs using our frequencies in 40,20 and 10 metre bands. There is absolutely no control over their working and existence by the local Government. It is very difficult for the licenced Indonesian amateurs to find a clear frequency in the lower edges of 40mb for their authorized communications. Generally the licenced Indonesians are around 7050,7055 and 7060 kHz for their traffic. 7050 kHz frequency, carries CW lessons for the intending future amateurs. Otherwise, the licenced ones, operate in their own nets and you can clearly identify their call signs in between, as per standard practice, though the entire conversations are in Indonesian.
The other frequency regularly used by a SE Asian group for two-way non amateur communications is 14044 J3Eu mode around 0100 UTC every day. Unfortunately, we need the services of those of you knowing SE Asian languages to identify them. It is not from INS or THA. May be from XV, 3W or XU area. We request all the SE Asian amateurs to watch out this frequency and identify the users.
July 2002
The presence of Indonesian non amateur groups on the various amateur band frequencies in the 40 and 20 metre bands is causing the most severe conceren for all the amateurs of Region 3 and the world over. While they use amateur radio frequencies for their regular communications, you will never miss the many calls for the Prayers and the many jokes and the Kookaburra pattern of laughing with old men and young ladies together. The 40 metre band has several channels of 5 kHz intervals from the lower edge and these stations have their breeding grounds here. They graduate to other frequencies and move to 20 metre band, where they are on either sides of the International Beacon frequency of 14100 kHz. None of us in Region 3, can monitor any NCDXF/IARU beacons on this frequency. This QRM from Indonesians are being reported month after month, and unfortunately, nothing is happening.
June 2002
There is a reported increase in the number of non amateur stations from Indonesia and China, as can be seen from the Australian report. While the conditions of propagation show an improvement, the increase is there, all over the other areas of region 3, as well. The increase of the Fishing Trawler traffic with the easily available amateur equipment, which can be conveniently fitted and used on the vacant amateur frequencies, is pronounced. As there is no law covering the seller of the equipment to sell amateur radio equipment only the bonafide amateur users, in the SE Asian countries, the use has become the order of the day.
May 2002
The Regional Monitoring Systems Coordinator heartily congratulates Chairman Fred Johnson ZL2AMJ, of IARU Region 3, on his receiving Queen’s Birthday Honours. It is an honour to Amateur Radio, Region 3 and New Zealand. The other person from New Zealand, who was honoured long ago, was late Arthur Cushen of Invercargill who was connected with Short Wave Listening and DX Programme-Broadcasting, both of which were known the world-over, to all the SWLs and Broadcasting Stations. The scene in Region 3, going strong with the various pirate groups from Indonesia, the many Fishing Trawlers from Sri Lanka and India, taking to amateur radio bands including WARC bands, is indeed alarming. We are not seeing any action taken by the Administrations of the countries concerned, but an occasional Amateur challenging these stations. All the National Societies are requested to take up with their respective Administrations whenever they are finding such reports in these columns, so that the pressure is put for our legal use of amateur radio frequencies.
April 2002
This months report from Australian Area mainly deals with their ususal Chinese, Indonesian non amateur traffic apart from the Harmonic broadcasts from Pyongyang. Other stations reported include those of the data traffic with VFTs, and hundreds of CB type transmissions from Chinese speaking stations.
March 2002
On a reference to OM Chen BA1HAM, regarding the 3rd Harmonic signals received on 18105 kHz, from the Yun Nan B/S, with its fundamental on 6035 kHz, OM Chen took keen interest to interact with the broadcaster. There appears to be some action taken, may be in the form of changes in the equipment or feed line or antenna, and the results are showing and we have not heard the harmonic for the past month or so. We thank OM Chen for the excellent work he has done to solve the problem by direct interaction with the Broadcaster in China.
February 2002
In the last week of January 2002 and early February 2002, BBC Cyprus relay transmitters on 7165 and 7320 kHz produced an intermodulation product (2×7165-7320) on 7010 kHz. This was logged from about 0100 UTC with Hindi, Urdu and Pashto upto about 0230 UTC, all over India. The 40mb CW portion was affected and many South Indian amateurs sent direct complaints to the Regional MS Coordinator. Working within the Terms of Reference, the Regional Coordinator had requested OM Ron Roden, the MS Coordinator of Region 1 and Mr K.C.Selvadurai, 9V1UV, Director IARU Region 3, to help using the good offices of their contacts. In the mean time, quite a number of complaints went direct to BBC through E-mails. All these resulted in the problem getting solved very early by the BBC authorities. The Regional MS Coordinator wishes to thank all those who helped and emphasise again that the proper contacts with a Broadcaster can solve the problems very early.

A NEW YEAR’S MESSAGE
From the President of IARU to Bob Knowles, ZL1BAD, IARUMS, International Coordinator.
Dear Bob:
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.

December 2001
Hearty welcome to the Pitcairn Island Amateur Radio Association (PIARA) to the Monitoring Systems Group of Region 3. We wish to hear PIARA nominating one of their active amateurs for Monitoring Systems work, so that Region 3, has the advantage of having the observations from the area, so close to Region 2. Reports from Australia and new Zealand say about the signals from Quang Zou transmitter from Mainland China on 18085 kHz. And the Indian sub continent experiences the 3rd harmonic signals from Yunnan B/S on 18105 kHz. The number of Indonesian pirate operations are continuing unabated on various frequencies in the 40 and 20 metre bands. The data transmitting stations occupying about 4 kHz bandwidth are also reported from VK/ZL area. The harmonics of DPR-Korea is still continuing on various frequencies of the 20mb, especially the 5th harmonic from 2850 KHz on 14250 kHz, daily, in the VK region
November 2001
The IARUMS Region 3, heartily welcomes OM Henry Andersson VK8HA of WIA, OM Toshiyuki Kondo, JR1NVU, of JARL. VoA was heard in English on 14215 kHz from 1700 to 1800 UTC in New Zealand and areas of region 2. The R2 MS Coordinator OM Martin, contacted the concerned in the VoA, and the problem has been solved.

The situation in Region 3, continues to be bothered by the several harmonics from DPR-Korea, the various other VFTs on many bands, the other regular broadcasters (except VoSharia, which has gone off 7085 kHz now) and the reduced activity of the jumping jammers on the 40 mb frequencies. The spurious “Christian Voice” radio signals on 21420 kHz frequently reported by VK8HA from Darwin area, gets highlighted this month, as it was heard as far away as in New Zealand too. The Monitoring Coordinators are contacting the concerned broadcaster for solving this problem.
September 2001
All the members of Monitoring Systems of Region 3 offer our heartfelt condolences to the family members of those killed in the attack on World Trade Towers, and to those families of Officers of Police and Fire services of New York, who lost their lives while helping in the search and rescue of the victims. We highly appreciate our American brethren amateur radio operators, who have been managing the Disaster Communications.
August 2001
The loggings for the month of July 2001, has the following items in common as reported from Australia. DPR Korea-R. Pyongyang: 3560 kHz; 1000 to 2100 UTC. Beacons C and S from Russia: 7039 kHz. 24 Hrs. DPR Korea-R Pyongyang harmonics/spurious: 14000.8,14025,14100,14155,14240,14250,14280 kHz; various times. Wide band pulse transmissions: 24950 to 24990 kHz ; <0200 to> 1500Hrs The pattern now is slightly different and seems to peak around 24996.5 kHz With two closely spaced pulses. The jammer from Cuba: 18090 kHz.
July 2001
The broadcast stations and their harmonics, the VFTs, the wobble/bubble/jumping jammers, and the many unidentified South East Asian non amateur networks are the ones who are finding regular mentions in these columns. The Voice of Broad Masses from Eritrea with a strong signal on 7100 kHz; Voice of Sharia on 7087 kHz(variable) from Afghanistan; the Voice of Mujahideen on approx. 7070 kHz; the Vietnamese and Chinese broadcasts from Yunnan Broadcasting service, China, on 3×6035 kHz are the regular ones.
May 2001
The 12metre pulses reported between 24900 and 25000 kHz, are reported by OM Bert PA3GIO, as CODAR- wide band pulse type transmissions for measuring various things like the height of waves at sea. It may indirectly mean that surveillance of the high seas can now be made, for any sailing vessels, friend, foe or contraband carriers. These wide band pulses heard Region 3, and reported some time back, are confirmed to be originating from Australia, as a military experimental exercise.
April 2001
The activity of the month of March 2001, was no different to the earlier ones. The only change was the variation in the propagation conditions for the onset of Summer and solar activity which was very pronounced. The harmonics, spurious products reported on many frequencies continued along with the data stations, jammers and others as reported by the different Societies.
March 2001
The 20 metre amateur radio band is a wide stage for every kind of broadcast spurious/harmonics to be noted on a regular basis, mostly coming from Far Eastern Region and Indonesia. Japanese Monitors have been reporting DPR-Korea on 14025,14080,14100,14125,14129,14155,14250 and 14280 kHz. Monitors from Australia/New Zealand report Chinese transmissions on 14210, DPR-Korea on 14220 and 14280 KHz.
February 2001
The number of reports of fishing trawlers using the various amateur radio frequencies is on the rise. We had heard the trawlers from Japan using the 80 metre band frequencies in the past. Now, the things have changed to the worse. We hear very regular use of the 20 metre band frequencies by the Indian fishing trawlers belonging to Andhra Pradesh who keep communicating in Telugu and English at times.
January 2001
The winter conditions have given good propagation and reception of fundamentals, harmonics and spurious signals from Broadcasters. Thus, those frequencies and countries frequently reported in these columns have been heard positively again. The very strong signals from Iran on 7070 kHz in the mornings and evenings are sporadic and peculiarly carry the jammer signals on the same frequency. The frequently identified word being ‘mujaahideen’.
