IARU Region 3 approves new 15m satellite allocation

The IARU Region 3 Directors meeting was held in Tokyo September 2-3. A modified interim Region 3 bandplan was approved which included an Amateur-Satellite Service allocation in the 15m band.

The Chairman of IARU Region 3 directors, Wisnu Widjaja YBØAZ and the directors Ken Yamamoto, JA1CJP, Peter Young, VK3MV, Don Wallace, ZL2TLL, Jakkree Hantongkom, HS1FVL, Mohd. Aris bin Bernawi, 9M2IR met in Tokyo for their annual Directors’ meeting at the conference room of JARL. They were assisted by the IARU Region 3 Secretary Shizuo Endo JE1MUI. They were joined by IARU President Tim Ellam VE6SH and Region 2 President Reinaldo Leandro YV5AM.

The directors reviewed progress on tasks directed and identified at the last Directors’ meeting and the Regional Conference that were held in Seoul, Korea in September 2018.

The finance situation of the region was noted to be healthy and well within budgets set earlier.

Reports were received from the Chairman, Directors and the Secretary. They mainly reported subjects on the responsibilities allocated to each of them.

Reports were also received from the Region 3 committee chairmen and coordinators. Those include reports related to Monitoring System, Bandplan Committee, EMC, Disaster Communications, ARDF activities in some societies and Award manager.

Reports including an oral report were also received from the IARU president and Regions 1 & 2 secretary. Their reports include issues such as current situations on agenda items concerned the amateur services towards WRC (World Radiocommunication Conference)-19, administrative issues and activities in their own areas.

It was noted that some IARU Region 3 societies are no longer active and the Directors are looking at a way to involve the amateurs in these countries in IARU activities.

Other important issues to our Region were also discussed. Those include the revision of Newsletter guideline and use of social media in IARU Region 3, new structure of IARU Region 3 website and Region 3 YOTA (Youth On The Air) program.

It was recognized that usage of a social media in addition to the newsletter is useful to enable a better communication with the IARU Region 3 member societies and their members. Furthermore, it is also recognized that societies are encouraged to provide information which is included in a Region 3 newsletter and monitoring system newsletter.

It was decided that an IARU Region 3 YOTA activity will take place in Pattaya, Thailand in October 2020.

The modified interim Region 3 bandplan proposed by the Region 3 Bandplan Committee was approved. A notable change was addition of a satellite portion in 15m Band as agreed at the last Region 3 Conference.

It was agreed to make a necessary action to extend the MOU (Memorandum of understanding) with APT (Asia-Pacific Telecommunity) which is to be expired in coming December.

The Chairman, Wisnu Widjaja YBØAZ and a Director, Ken Yamamoto JA1CJP will be present at the next Administrative Council meeting and the Region 2 Conference which will be held in Lima, Peru from September 28 to October 4, 2019.

It was agreed that the next directors meeting be tentatively fixed for the 1st to 3rd of October 2020 in Thailand.

CEPT CPG decides position on 144, 50 and 1240-1300 MHz

CEPT Logo“At the insistence of the European Commission, a WRC-23 agenda item was considered necessary to address the world-wide protection of Regional Navigational Satellite Systems from amateur emissions in the band 1240-1300 MHz.”

The CEPT ECC CPG met in Ankara during August 26-30 to finalise their position ahead of the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.

RSGB volunteers along with other radio amateurs in IARU Region 1 countries put in a considerable amount of work to defend the amateur radio allocations. Their hard work ensured the removal of 144-146 MHz from a study of additional spectrum for aeronautical applications and an agreement on a European Common Proposal for 50-52 MHz.

IARU Region 1 have released this report on the meeting:

The CEPT Conference Preparatory Group met this week in Ankara, Turkey. Items of interest to the amateur service which were finalised were:

– Agreement to a European Common Proposal (ECP) on allocating 50-52 MHz to the amateur service in Region 1 on a secondary basis with a footnote listing those countries where the amateur service will have a primary allocation in the band 50-50.5 MHz (WRC Agenda Item 1.1)

– Agreement to an ECP on spectrum to be considered for International Mobile Telecommunications, which does not now include the primary amateur band at 47-47.2 GHz (WRC Agenda Item 1.13)

– Agreement to an ECP that retains the current regulatory position in the 5725-5850 MHz frequency band which includes secondary allocations to the amateur service and the amateur-satellite service (WRC Agenda Item 1.16)

– Removal of 144-146 MHz from a French proposal for study of additional spectrum for aeronautical applications. (WRC Agenda Item 10)

– At the insistence of the European Commission, a WRC-23 agenda item was considered necessary to address the world-wide protection of Regional Navigational Satellite Systems from amateur emissions in the band 1240-1300 MHz. A draft WRC Resolution was agreed which underlines the importance of this frequency band to the amateur service and explicitly excludes the removal of existing allocations as part of the proposed agenda item. (WRC Agenda Item 10)

– There was no change to the already agreed CEPT position on Wireless Power Transmission (WRC Agenda item 9.1.6). This states that no change is needed in the Radio Regulations to address the question of operating frequency for WPT-EV, but leaves open the question of spurious emissions from WPT-EV.

Commenting on the outcome of CPG, IARU Region 1 President Don Beattie, G3BJ, said that the IARU team at Ankara (the only representatives of the amateur service at the meeting) had presented clear and convincing arguments for the amateur service position and he was pleased that regulators had recognised the strength of the amateur case. He expressed his thanks to everyone who had contributed to the outcome at CPG.

The issues now move to WRC in Egypt in November for final resolution. IARU will be there.

Note: Although the CEPT position includes a Primary allocation at 50.0 to 50.5 MHz it is for the Amateur Service only – the Amateur Satellite Service is excluded.

144-146 MHz WebSDR at Goonhilly now available

Goonhilly 144 MHz WebSDR

Goonhilly 144 MHz WebSDR

AMSAT-UK and BATC have announced the availability of a new 144-146 MHz Web-based Software Defined Radio installation at Goonhilly.

This is being provided in collaboration with Goonhilly Earth Station where it is kindly hosted alongside the existing receiving equipment for the amateur radio transponders on the Qatar-Oscar-100 (QO-100 / Es’hail-2) geostationary satellite.

It shares the same Turnstile antenna that is used for the reception of the AO73, EO88 & JO97 CubeSats.

Being located in the far South West of the UK, it is anticipated the SDR will be useful for early Acquisition of Signal (AOS) of 144 MHz downlinks from amateur satellites and the International Space Station (ISS). Additionally it can be used for reception of tropospheric signals from the south – the Spanish beacon ED1ZAG on 144.403 MHz has been already been heard on the system.

The new 144 MHz band WebSDR is available at

The AMSAT-UK / BATC 10 GHz WebSDR for QO-100 is still available at

The team are looking for suggestions for:
• Conformation of the satellite (2U / 3U)
• Orbit (LEO / MEO)
• STEM Outreach
• Amateur Radio Payloads
• Research Payloads

Please email your ideas to:
funcube-next <at>

The topic will be discussed during the AMSAT-UK Colloquium on Sunday 13th October 2019
