RAST will host a monthly meeting on December 12, 2021 at Baan Im Sabuy

Thanks to the easing of restrictions, there will be a RAST meeting on the second Sunday of December at Baan Im Sabuy, an outdoor restaurant in Bang Bua Thong District of Nonthaburi in the northwestern suburbs of Bangkok.
All members are invited to attend the meeting on December 12 and the location, being outdoors, is to comply with social distancing considerations for safety during the Covid-19 pandemic. This had been the location of the November 2020 RAST meeting.
The meeting will begin at 11.30 a.m. and a buffet lunch will be available while RAST President Jakkree Hantongkom, HS1FVL (Jack) will bring those present up-to-date with developments regarding amateur radio in Thailand.
Here are directions to the restaurant from central Bangkok: Head north along the Si Rat Expressway and take the Chaeng Wattana exit where you should turn left onto Chaeng Wattana Road and then drive in a westerly direction. Continue along Chaeng Wattana Road to the bridge over the Chao Phya River after which the highway becomes Chaiyapreuk Road. Continue further to the intersection with Ratchapreuk Road, which is a distance of around 10 Km from the Expressway.
Before this intersection, there is a sign for Highway No. 345 which is a right turn onto Ratchapreuk Road. You need to follow this and head north along Ratchapreuk Road for 2.7 km to the intersection with Highway No. 345. There you need to turn left (heading west, towards Kanchanapisek Road) and you should follow Highway 345 for 1.9 Km after which there is a sign (in Thai) for the restaurant where you need to turn left and proceed for around 100 metres to the parking area.
The following link shows the route on Google Maps from Chaeng Wattana Road (after leaving the Expressway) to the restaurant:
If you or your taxi driver needs instructions for the best route to take, the phone numbers of the restaurant are 091-8292651 and 080-1942665. The restaurant also has a facebook page:

The IARU Region 3 virtual Conference was a success

RAST hosted the 18th International Amateur Radio Union Region 3 Conference virtually from September 20-22, 2021 using Zoom, with over 90 participants from all over the world.
On Sunday September 19, the conference was preceded by a meeting of IARU R3 Secretary and directors, also attended by member society representatives, when nominations or volunteers were requested for the chairpersons and secretaries of working groups, and for the finance committee, while the virtual voting process was reviewed.
This was the first time that this conference, which is conducted every three years, has been held virtually because of concerns and travel restrictions due to the Covid-19 pandemic.

The conference itself began at 10 a.m. on Monday, September 20 with an opening address by Dr Panit, HS1AAZ, while the Chairperson of the conference was Bun, E25KAE, who began the conference with a minute of silence for silent keys Larry Price, W4RA, Reinaldo Leandro, YV5AM, Ramaiah Ramachandra, VU2RCR, Sangat Singh, 9M2SS, Halim Dani Hidayat, YB2TJV, Arasu Manomar, VU2UR, Roberto C. Vicencio, DU1VHY, Faisal Al-Ajmi, 9K2RR.

IARU R3 Chairman of Directors Wisnu, YB0AZ makes his opening address.

The Chairman of the Region 3 Directors, Wisnu, YB0AZ then made his opening address during which he stressed the need to keep the amateur radio spectrum safe and that we should promote amateur radio to young people.

Following this, the IARU president since 2009, Tim Ellam, VE6SH welcomed everyone but noted that between 144 MHz and 275 GHz 9 percent of the spectrum was allocated to amateur radio and this could be in jeopardy.
Other opening addresses were made by Mario Maniewicz, the ITU Radio Communication Bureau Director in Geneva, the APT Secretary General Masanoni Kondo and NBTC Commissioner Gen Sukit Khamasundara. After that, there was a RAST video presentation.

Then, the delegate for RAST, Champ. E21EIC, proposed that Bun, E25KAE be the Conference Chairperson, which was endorsed by ORARI and approved. The Region 3 Secretary then summarized the directors' meeting.

Bun, E25KAE impressed conference participants with her skilled management of the conference as the Chairperson.

Representatives of 18 member societies were attending the event and each society made a presentation of their report to the IARU Region 3 Conference to all participants.

Details of these reports and other conference documents can be found at the IARU R3 website
There were also proposals for changes in the IARU R3 constitution, a discussion on threats to amateur radio and recommendations for changes to the IARU R3 band plan that were among topics discussed and reviewed, with amendments to documents and proposals later being approved.
There was a also finance committee meeting and various working groups discussed proposals and recommendations in Zoom breakout rooms. Finally there was an election of six IARU Region 3 directors for the next three years, along with a Secretary for the period.

Dr Panit, HS1AAZ President of the Conference, declared the conference open on Monday September 20, just after 10 a.m. (Thailand time) and his closing speech was made on Wednesday, late in the afternoon.

The directors elected were Wahyudi "Yudi" Hasbi, YD1PRY, Dr.Jack J. Hantongkom, HS1FVL, Katsumi "Ken" Yamamoto, JA1CJP. Oscar Reyes, VK3TX, Mohd Aris Bernawi, 9M2IR and Don Wallace, ZL2TLL while the newly-elected Secretary for Region 3 for the next three years was Yuki Yosuke Uchiyama, JH1NBN.

Yuki Yosuke Uchiyama, JH1NBN was elected as IARU Region 3 Secretary for the next three years.

As for the Chairman of the directors, it was decided that this position would be held by two of the directors, each for 18 months, with Ken Yamamoto, JA1CJP being Chairman for the first 18 months and Yudi, YD1PRY holding the post for the second 18-month period.
A RAST proposal to host the 19th IARU Region 3 Conference in three years' time in September 2024 was also voted on and adopted during the virtual conference and it is sincerely hoped by RAST that by then it will be able to host the conference in person.

RAST conducts AGM meeting and hosts New Year Party

Members vote to approve the minutes of the 2019 AGM during the meeting at Rot Meu Mae on Sunday, April 4, 2021.

On Sunday, April 4, RAST hosted its AGM meeting for 2020 at the Rot Meu Mae restaurant in Laksi which was well-attended and, after the formal meeting was over, the gathering enjoyed a belated New Year Party with an exchange of gifts while there was also a lucky draw for some Icom transceivers and other equipment.
There were around 100 members and guests present at the restaurant while the meeting began with the approval of the minutes for the 2019 AGM meeting last year. Then, RAST President Jakkree Hongtongkom, HS1FVL, summarized the activities of the society during the meeting (a link to the English version of the activites can be found here) while there was also also a summary of the income and expenses of RAST over the past year.
Many RAST activities during 2020 had been cancelled due to the Covid-19 coronavirus pandemic and there had only been a few monthly meetings during the past year for this reason.
Hopefully, some of the accompanying photos here capture the festive mood of the meeting.

November RAST meeting

RAST conducted a monthly meeting for November on the first of the month at Baan Im Sabuy, a restaurant in Bang Bua Thong District of Nonthaburi in the northwestern suburbs of Bangkok. The meeting was conducted in an outdoor environment to enable members to practice social distancing in order to avoid any risk of contracting COVID-19.
The turn-out was relatively low, however, with around 25 members attending the event when the RAST President Jakkree Hantongkom (above right) announced that it was important that RAST co-ordinated with the King Mongkut Institute of Technology North Bangkok's space program. He said that Apiwat (Pao) HS4SCI, a former space engineering student, would be helping in this on behalf of RAST.
Thanks to RAST Secretary Champ, E21EIC, for the details and accompanying photographs.

The next get-together will be RAST on the Beach event on October 3-4, 2020 in Rayong

There will not be a RAST meeting in September, 2020 due to Covid-19 concerns and also because the first weekend of September is a "long weekend" with Friday, September 4 and Monday September 7 being substitute Songkran holidays.
Instead, the next meeting of RAST will be conducted in Rayong on the first weekend of October when the third "RAST on the Beach" (ROB) event will be hosted on October 3 and October 4 at the Rock Garden Beach Resort in Rayong.

Jack, HS1FVL re-elected
President at AGM meeting

The March Annual General Meeting of the Radio Amateur Society of Thailand under the Patronage of His Majesty the King (RAST) was well attended and saw the society's President, Jakkree Hantongkom (Jack), HS1FVL re-elected as president along with most of the former committee members who were also re-elected at Sena Place Hotel on Phaholyothin Soi 11.
The formal meeting began after a buffet lunch and after waiting for a period of over one hour, after which the number of members present, who comprised 79 members of RAST, constituted a quorum for the AGM meeting.
The AGM began with the approval of the minutes of the 2018 AGM and this was followed by a summary of the activities of the society over the previous year by the President which was followed by a version in English by RAST Vice President Tony Waltham, HS0ZDX.
(The full version of the activities in English can be found here)
After that, an auditor was appointed to oversee the accounts of RAST and RAST Treasurer Pornpimol Suksansomphop, HS0VDX summarised the income and expenses of RAST over the past year.

Singh, 9M2KN relayed by Tony, HS0ZDX, there was an explanation from the RAST President as to why RAST would be unable to host the annual SEANET Convention this year. SEANET 2020 is scheduled to take place in northern Thailand after Ponwat, HS1XIM and Dave, HS1LCI agreed to host the event this year during the 2019 SEANET Convention in Johor Baru, Malaysia.
Jack explained that RAST was already committed in October this year to being the host of the IARU Region 3 youngsters on the air (YOTA) event and an IARU directors meeting in Rayong Province and thus would be unable to take on the SEANET Convention as well this year.

The votes for the RAST committee members are being counted: Sakon, HS1JNB turns to Pomchanok (seated at right) who is counting the votes.

After that, Sakol Nakin, HS1JNB was appointed to oversee the voting for the President of RAST for the next two years as well as for 9 members of the executive committee for RAST. Then, names of 15 contenders were proposed by members present and then the voters filled in lists of nine of the 15 names recorded on a whiteboard on slips of paper.
Jakkree, HS1FVL was the sole contender for President of RAST and was unanimously re-elected and following that 15 contenders for executive committee members were proposed and their names were recorded on a whiteboard.
Then the voting took place after which the tallies were recorded on the whiteboard next to the names and then those with the top nine vote counts were automatically nominated to the RAST committee for the next two years.

NBTC and RAST host International Alliance Volunteers Conference

Thailand's first major conference about emergency communications for amateur radio took place on November 16, 2019 at the National Broadcasting and Telecommunications Commission (NBTC) Secretariat in Bangkok with representatives of 16 countries and Thailand participating.
Called the International Conference Volunteers 2019 Conference, the objective was to promote the development of volunteering for amateur radio communications during crises and disaster events and to enhance the partnership between amateur radio operators for long term cooperation and international goodwill.
Participants also paid obeisance to His Majesty King Vajiralongkorn, King Rama X, to commemorate his recent coronation. King Rama X is the patron of the Radio Amateur Society of Thailand and has the callsign HS10A.
RAST jointly hosted the conference with the NBTC that was attended by over 100 delegates. Representing the International Amateur Radio Union (IARU) was the Region 3 Chairman, Wisnu Widjaja, YB0AZ, along with a Region 3 Director, Don Wallace, ZL2TLL, who both made presentations about the role of amateur radio volunteers in disaster and crises in foreign countries.
There were also many other presentations by representatives of national amateur radio societies. Also making a presentation during the conference was the IARU Region 3 Secretary, Ken Yamamoto, JA1CJP, who also represented the Japan Amateur Radio League (JARL). Other presentations were made by representatives of several national amateur radio societies including the German Amateur Radio Association (DARC), the Indonesia Amateur Radio Association (ORARI), the Philippines Amateur Radio Association (PARA) and the Luxembourg Amateur Radio Society (RL).
The countries that were invited to participate in this conference were those with a bilateral reciprocal agreement with Thailand, along with Finland where an agreement is almost finalized. There were also representatives from countries in Asia including Japan, Malaysia, Indonesia and the Philippines that had been invited to participate.
The RAST presentation was about lessons learned from the Tham Luang cave incident in Chiang Rai, northern Thailand, when a junior football team of 12 boys aged between 11 and 16 were trapped, along with their coach, for over two weeks in a vast cave complex following flooding in late June and early July of 2018. Speakers who recounted the incident on behalf of RAST at the conference were Larry Riser, HS0ZKZ, Dr Pakorn Watanachaturaporn, HS1EFA and Pornchai Semjang, HS2JFW who is also a former president of the society.
There was also an emergency medical project explained by a senior adviser to the KDDI Foundation, Mr Yosuke Uchiyama, JH1NBN and Dr Pairoj Boonsirikamchai, a deputy secretary general of NIEM, the National Institute for Emergency Medicine.
The event enhanced the partnership between the countries involved whose representatives had participated in the event and the conference helped to promote awareness of the significance in the role that amateur radio operators can play when an emergency such as when extreme weather, an earthquake or a tsunami occurs.

Tanan and Anant explain aspects of the QO-100 geostationary amateur radio satellite at the November RAST meeting.

Satellite update at November meeting

The highlight of the November RAST meeting at Sena Place Hotel on Sunday, November 3 was a presentation by Tanan Tangseeprom, accompanied by Anant, HS1GAB, about contacting the first geostationary satellite for amateur radio, Es'hail or QO-100 (short for Qatar Oscar 100) from the JAISAT Ground station, HS0AJ and the RAST club station at Rajapruek University, HS0AC.
Currently, these are the only two stations authorized by the NBTC to make such contacts, although, with the right equipment, other hams in central or western Thailand would be able to listen to signals from the satellite which is over Africa and as at about a 6 degree angle above the horizon from Bangkok. Thailand is right on the fringe of the signal map and it would be impossible to listen or make contacts from the Northeast of Thailand.
The first contact made from the HS0AJ Ground Station was with PY2RN in Brazil on March 10, 2019 and the illustration below shows the footprint of the satellite, with Thailand and Brazil at opposite sides.
Also at the meeting was an EME enthusiast, Alex, HB9DRI and previously his callsign had been ZS6EME when he was based in South Africa and who will be based here for four years and has already applied to join RAST.

The July RAST meeting was well attended with almost 50 members and guests present including newcomers Louis, G4OJW and VK5EEE, along with Eric, F5TVK. The highlight of the meeting was a summary of Thailand's first amateur radio satellite, JAISAT-1, which was launched by a Soyuz rocket two days prior to the meeting on July 5, 2019.
The launch reflected several years of efforts by the JAISAT-1 team led by Tanan Rangseeprom, HS1JAN who had been inspired to create an amateur radio satellite after experimenting with amateur radio ballooning activities with efforts having begun in 2013. The abbreviation "JAISAT" is short for the "Joint Academy for Intelligent Satellites for Amateur Radio of Thailand."
Later, in July 2015, the NBTC's Fund for the Research and Development of Broadcasting, Television and Telecommunications for Public Benefit approved a 9.3 million baht budget for the JAISAT-1 amateur radio satellite project and since then efforts by the JAISAT team, with assistance from various agencies and organizations, notably Japan's JAMSAT have been ongoing.
A summary of the activities, including an explanation of the assembly and testing of the cubesat satellite with videos and slides, was provided during the meeting by representatives of the JAISAT-1 team led by Tanan, HS1JAN, along with Anant, HS1GAB, Chakaj, E21QJU and Masanobu Tsuji, JA1DAO.

Congratulations to everyone who was involved in this significant project.

The June meeting of RAST is cancelled, the next meeting will be on July 7, 2019

Since many people will be travelling outside Bangkok over the weekend the Radio Amateur Society of Thailand under the Royal Patronage of His Majesty the King (RAST) has postponed the next monthly meeting to July and it will be held at Sena Place Hotel, as usual, on Sunday July 7 from 11.30 a.m. onwards.

The highlight of the May RAST meeting was the provision of application forms to take the upcoming Intermediate Class examination on August 24 at Bangkok University's Rangsit campus and there were a lot of visitors who had attended the meeting for the opportunity to apply to take the exam.
The society usually meets on the first Sunday of the month, but the previous weekend coincided with the coronation ceremonies of His Majesty King Maha Vajiralongkorn, King Rama X, when RAST committee members were busy activating a special event amateur radio station using the callsign HS10KING/mm.
The special station was operating aboard the Royal Thai Navy aircraft carrier the Chakri Narubet which had put to sea from Sattahip to mark the coronation. A total of 23 RAST operators had been active on the HF and VHF bands as well as using satellite frequencies and who made a total of 4,143 QSOs from May 2 to May 5, 2016 with QSOs with a total of 131 countries and the chart that follows shows the QSO statistics in detail.

The callsign HS10KING is still valid, and will be so until the end of July, and any members who wish to seek permission to operate using this call should contact Wanlop, HS6MYW.
At the May meeting, RAST President Jakkree (Jack), HS1FVL also announced that the society had issued the callsign HS10A for His Majesty the King, King Rama X.
He also observed that the RAST's 55th Anniversary celebrations in March had been a big success with the attendance of over 430 members and guests being far more than had been anticipated and with radio amateurs travelling from many far-flung provinces, such as Narathiwat, to attend.
RAST has also received permission to operate on UHF in the 70 cm amateur radio band from 438-439 MHz for a six-month period while its application for "temporary licences" for Malaysian amateur radio operators is almost complete, when the callsigns in the format HS0/9M2xx will be authorized for six months or a year.
If all goes well with this temporary licence agreement, RAST also hopes to extend it to include other countries in the region such as Indonesia and the Philippines, Jakkree said.
The next informal RAST meeting will be on Sunday, June 2 at Sena Place Hotel from 11.30 a.m. onwards.

A newcomer introduces himself to others present at beginning of the formal part of the May RAST meeting.
