RAST celebrates 55 years and hosts the 2018 AGM

The Radio Amateur Society of Thailand under the Patronage of His Majesty the King (RAST) celebrated its 55th Anniversary at Sripiamsuk Resort on Saturday, March 2, 2019 with a day-long event attended by almost 500 members and guests.

Antennas were installed in a field at Sripiamsuk Resort to enable HF activity during the party.

E21FYK was one of the operators of the HS55RAST station to commemorate the event.

The gathering at the resort in Pathum Thani Province just to the north of Bangkok included lunch and dinner while there was draught beer available at no charge to guests while there were lucky draws for prizes throughout the day and evening with a total of 55 radio transceivers being among the prizes that were won.
An amateur radio station with HF antennas had been set up on a field at the resort and the station operated using the callsign HS55RAST.

There was a wide range of equipment, both new and second-hand, on sale at the event.

Solar power inverters were among the equipment on sale at discount prices at the party.

The anniversary event was also an excellent opportunity for RAST members to obtain equipment, both second-hand and new, that was on sale at various stalls around the event.
There were also demonstrations of the assembly of amateur radio kits while Icom took advantage of the occasion to launch its latest IC9700 HF transceiver and had an elaborately decorated booth along with attractive YLs who posed for photographs with members and guests.
During the afternoon, beginning at 13.30 after lunch, RAST also held its Annual General Meeting attended by around 100 members who were provided with the agenda (in Thai) when they registered for the meeting.

The RAST 2018 AGM was held in a meeting hall at the Sripiamsuk Resort on the second floor.

This included details about RAST's income and expenditure for the past year, the minutes of the 2017 AGM, a summary of RAST's activities during 2018 and the RAST QSL Bureau report for 2018-2019. Presiding over the meeting was Pomchanok Palakawongse na Ayudhaya, E23PKO.
During the AGM meeting, RAST President HS1FVL announced that E23FXX had been appointed as a special advisor to RAST, while members present approved the minutes for the 2017 AGM held last year. Prateep Saengthammarat was also approved in a vote to be the auditor of RAST for the next 12 months and details about income and expenses, RAST's membership details were acknowledged. Then, E23NEZ was proposed and approved as a new committee member for technical affairs and there was a proposal that foreign members joining RAST be obliged to become Gold Members with a lifetime membership fee of 5,000 baht.
RAST President Jakkree, HS1FVL made a summary in Thai of the activities of the society in 2018, while Tony, HS0ZDX announced that an English-language version can be viewed on this website here.

Then there was a proposal that the restriction on the number of consecutive terms that a president of RAST can serve, which currently limits this to two terms, be lifted. This was proposed from the floor by Joe, HS2JFW and there was some debate and a clarification that the RAST president still needs to be elected by members, while it was explained there were many issues that a RAST president needs to continue to pursue such as seeking permission for the six-metre band, the JAISAT-1 satellite project and reciprocal licensing. In the end, 88 members out of a total of 99 present voted to endorse the proposal to cancel the two-term limit for a RAST president.

RAST President Jakkree, HS1FVL, awards a Yaesu FT-4V handheld as a lucky draw prize to E22EEO (at right).

Kits were assembled during the party at a table.

Following the AGM meeting which was held in the Sripiamsuk Resort's meeting hall, activities resumed outside, on the field and around its outskirts when there was an ARDF exercise while a game of musical chairs was also staged.

Most of the time, E23PKO, also known as Loong Nuad and pictured above at left, acted as a lively emcee and there were ongoing draws of door prizes for lucky winners. Later there was live music on the stage provided by Art, HS4LKW, followed by a few more announcements by RAST President Jakkree before the party wound up at around 22.00.

The other announcement he made was about six metres in that this year the military had opposed a request for amateur radio stations to operate in the band during the CQWW VHF Contest although he said that RAST was lobbying strongly for a permanent allocation in the six metre band from 50.00 MHz to 50.04 MHz and that he would keep members informed of developments.
The 55 Anniverary Party will effectively be the March RAST meeting and there will be no get-together on Sunday, March 3 at Sena Place Hotel.

Directions to Sripiamsuk Resort

(For a map and illustrated directions please click on this link to a pdf file)

Here is a summary of the directions from downtown Bangkok: Take the Sirat Expressway that heads north from Bangkok (on the Expressway simply follow the signs for Chaeng Wattana -- but don't get off there) and, after the Chaeng Wattana exit, continue on the Expressway, following the signs to Thammasat University - Rangsit Campus.
Around four and a half kilometres after the exit for Chaeng Wattana Road you will reach the exit for Si Saman Road. Leave the Expressway here and then follow the sign for Don Mueang which will take you over Si Saman Road in a loop that will lead you onto Si Saman Road (also known as the Prachachuen-Pakkred Road) heading east.
Proceed under the Expressway (towards Don Mueang) for half a kilometre to the first major intersection with traffic lights where you turn left into Liap Klong Prapa Road (the road sign says Rangsit). This is the road next to a canal (klong). Head north along the Liap Klong Prapa Road (keeping the canal on your right-hand side) for 2.3 Km and then turn left.
(There is a small green sign in Thai indicating a left turn for the resort there.)
Follow this road west for 350 metres (which takes you back towards the Expressway) to join the road that is underneath the Expressway. Turn left and follow this road under the Expressway for 550 metres and the road ends in front of the resort. Turn right and you will have entered the Sripiamsuk Resort.

Guests were entertained throughout the afternoon with music during the party at the Rot Meu Mae restaurant as hams are wont to keep a microphone busy...

Later, during the December meeting, Jack announced the revised date for the annual ARDF Championships which will now take place near Hua Hin on February 16-17, 2019.

College students explain plans for Cubesat satellite project

RAST President Jakkree, HS1FVL (right) offers to help Bangkok Christian College students to ensure that their equipment and ground station is properly licensed by the authorities.

The highlight of the RAST monthly get-together at Sena Place Hotel in November was a presentation about a project to launch a Cubesat satellite by high school students of Bangkok Christian College (BCC) in conjunction with King Mongkut's University of Technology North Bangkok (KMUTNB).
Following the buffet lunch, students from BCC took the microphones and, with the help of images projected on a screen, explained the school's space project which is to launch a 1U Cubeset by the end of 2019 or in early 2020 with four different cameras (Optical, Short Wave Infrared (SWIR), Near Infrared (NIR) and Red.
The ground station, which will use amateur radio frequencies, will be located in the grounds of the college on Sathorn Road where the roof of the building has an uninterrupted view of the sky. The satellite itself is being built in Thailand, but with some of the components being imported. The launch is planned to be in about one year's time, or slightly longer than that, using a Russian Soyuz rocket.
RAST President Jakkree, HS1FVL thanked the students for their presentation, which was made both in Thai and in English, and he said that RAST would help the college where it could, and particularly for getting licences for the ground station and for radio transmitting equipment from the National Broadcasting and Telecommunications Commission (NBTC) and help ensure that everything was legal and in order.
There is a TV channel 7 video about the project while additional information can be found here. There is also a good article in Thai in Thai Post here.

Following the satellite presentation, RAST President Jakkree made some announcements, including a planned Open House at Rajapreuk University where RAST has its HS0AC club station on November 15 where there will be a seminar in the morning, beginning at 9 a.m., and followed by a lunch.
Jakkree (Jack) also announced that the NBTC would be hosting its Amateur Radio Day exhibition in its grounds on Soi Sailom, Phaholyothin Soi 8, on Saturday, December 15. RAST will have tents at the event and will be operating on various frequency bands there and all members are encouraged to attend.
As a result, plans to host the ARDF Championships which had been scheduled for December 15, have been postponed and the event will take place either later in December or early next year. The location should be in the Hua Hin area and details will be announced later.

And to mark the beginning of 2019, RAST will host a New Year party on the second Sunday of January, January 13, at the Rot Meu Mae restaurant, which is the same location for the party as last year, and which not far from Laksi to the north of Bangkok. The party will begin at 3 p.m. and there will be a buffet with food and refreshments for 500 baht. This will also double as the January RAST meeting, so there will be no gathering on the first Sunday of the year.
The other major forthcoming event on RAST's calendar will be its 55th anniversary meeting on March 2 which will take place at the Sripiamsuk Resort in Pathum Thani to the north of Bangkok on the Chao Phya River. The event will begin at 10 a.m. and will also incorporate the society's Annual General Meeting. This will be a day-long event and members can stay at the resort overnight if they wish.
The next RAST meeting will take place on Sunday, December 2 at Sena Place Hotel while among those introducing themselves as either newcomers or returnees at the November meeting were Franz, DJ9ZB and HS0ZLP, Peter, HS0ZGM from Nan, Horst, HS0ZNV from Koh Lanta, Jakrapot, HS1ERP, Ken, VE3HLS and Uwe from Germany.

There is also a 65-minute video of the presentations and announcements on Facebook at this link.

Later this month, the annual SEANET Convention will take place in Yogjakarta, Indonesia where it will be hosted by Indonesia's national amateur radio society, ORARI, from October 18-21.
However, the location of the convention for the following year, 2019, has not yet been determined and so RAST has submitted a proposal to host the SEANET Convention next year in Phuket. This will be voted on during the upcoming convention and the outcome will be known later this month.
Jack also told those present at the meeting that RAST Vice President Ukrit, HS1AXC will be responsible for organizing the ARDF Championships and awarding the RAST ARDF trophy. The competition which will feature teams from amateur radio societies throughout Thailand will take place on the weekend of December 15-16 with the location being very close to Ratchaphat Park in Hua Hin in the province of Prachuap Khiri Khan.

The formal part of the meeting, after the buffet lunch, began with a surprise birthday cake for Charly, HS0ZCW who was celebrating his birthday. The cake, which had been sent to the event by his XYL, was presented with nine candles flickering as those present at the meeting sang the "Happy Birthday" song. Charly was all smiles as the staff cut the cake into slices to help him share it with others in the room.
RAST President Jakkree (Jack) began by saying that RAST's participation in the Tokyo Ham Fair the previous weekend had been a success, where RAST had a booth with over a dozen RAST officers and members taking part.
Jack then said that the next major item on the agenda would be the 17th IARU Region 3 Conference scheduled to take place on September 10-14 in Seoul, Korea when he along with four other RAST delegates would be participating.

The RAST President revealed that RAST would be seeking support from representatives of other amateur radio societies at the meeting for a request to be submitted to the National Broadcasting and Telecommunications Commission (NBTC) to seek permission for licensed amateur radio operators in other Asian nations to be permitted to operate here for up to three months with a temporary callsign HS0/homecall RAST would also be looking for support at the IARU conference from other societies to endorse an appeal for a 400 KHz allocation on the six metre band, from 50.000 to 50.400 MHz.
While in Seoul, Jack said he also hoped to have the opportunity to propose to the Organisasi Amatir Radio Indonesia (ORARI) that RAST would like to host the 47th Southeast Asia Net (SEANET) Convention next year in Phuket. This year, ORARI is hosting the convention in Jogjakarta from October 18-21.
At the meeting, E23PXX presented to Jack an educational video about amateur radio that was made by E23PKO, Pomchanok, a RAST committee member. (A link where the video can be downloaded will be provided on this website in the near future.)
In addition, the next Advanced Class amateur radio examination in Thailand will take place on October 21, 2018 for which a total of 122 candidates have registered, while the next FCC VEC examination will be conducted at noon at the KMIT North Bangkok campus on September 22.
The next RAST meeting will be on Sunday, October 7.

These Yaezu caps were received at the Tokyo Ham Fair and were distributed to RAST members at the September meeting in Bangkok.

August meeting

Champ recounts his participation in the 2018 WRTC Championships

The highlight of the August RAST monthly get-together at Sena Place Hotel on Sunday, August 5 was an account by RAST Secretary Champ, E21EIC of his trip to Germany to participate in the World Radiosport Team Championship 2018 last month.
He was invited to speak following announcements by RAST President Jakkree (Jack), HS1FVL, which included mention of upcoming trips to the Tokyo Ham Fair later this month where RAST will have a booth and participation in the IARU Region 3 Conference in September (Sept 10-14) in South Korea. Jack will lead delegations to both events, accompanied by RAST Secretary Champ, RAST Registrar JC Goi, E20NKB and RAST Committee member Apinant (Pop), HS1JZT.
Jakkree also mentioned that RAST intends to celebrate its 55th anniversary at the end of next February with a dinner party at a riverside restaurant or resort in Bangkok, the location of which has yet to be decided upon.

On the projector screen Benjamas, HS6SSE holds the "Thailand" sign with Ralf, HS0ZET, (at right) while Zaki, 9M2ZAK, at left, along with Champ and Goi look on.

Champ then took the microphone and illustrated his presentation with slides and a video taken during his trip to Germany, which had been the second time that he had participated in the WRTC Championships. This year he was joined by Zaki, 9M2ZAK from Malaysia in the Asia team.
He explained that he flew to Frankfurt on July 6 with baggage weighing 70 Kg and which had included equipment such as bandpass filters for use in the contest. While in Germany, he visited the Icom Europe office where he met Helmut, DF7ZS who helped by training him in the functions of the Icom 7851 which he would be using in the contest.
Then Champ travelled on to Wittenberg, the centre for the WRTC Championships this year and he observed that few Asians had been participating -- with only nationals from Thailand, Malaysia, Japan and Israel. He also praised Benji and Ralf (Benjamas, HS6SSE and DJ5BK, and Ralf Klinger, HS0ZET and DF6RK) who had taken good care of them in Germany.

The Spiderbeam antenna which had a problem with a high SWR and the balun and cable had to be replaced during the contest, forcing Champ's station off the air for three and a half hours.

The location for taking part in the contest as well as the callsign to be used was assigned through a lucky draw and they did not know the callsign they would be using until 15 minutes before the contest would begin, while the prefix of the callsign assigned -- Y86P -- was rare and had not been issued since 1990, he said. Champ also praised Fred, HS0ZAR and K3ZO, who, along with the PVRC (Potomac Valley Radio Club), had sponsored the tent used during the contest.
The antenna used had been a Spiderbeam, while there was a team of four local volunteer hams -- DL1UHU, DL6UD, DL7AT and DL9MWG, with the site manager being DM3BJ. The set up and testing of the station, which was located a long way out in the countryside, had begun one day before the contest would begin.
Once the contest was underway, Champ said he did not eat anything, and he had been on the radio non-stop, however, it turned out that there had been a big problem with the antenna balun and the connector which had lasted for three and a half hours. After one hour spent looking up at the antenna, the support team finally took the antenna down and then had to drive for two hours to fetch a replacement, which cost the team some 1,500 QSOs.
In all, the team made over 2,000 QSOs on both CW and SSB in 24 hours but having been forced off the air cost the team many points and they came in 61st place out of a total of 63 teams. The full results, with Lithuania coming in first place, Germany second and the USA in third place, can be seen here.
Champ ended his presentation by saying that he hopes to get a chance to participate in the next WRTC Championships in four years' time because of the antenna problem this year.
RAST, thanks to many contributions from donors, both corporate sponsors and individual members, had supported Champ's trip to Germany with a total of 189,000 baht, while Champ had only spent 149,000 baht and at the meeting he handed 40,000 baht back to RAST President Jack who said that the funds would help subsidise the upcoming trip by RAST members to the Tokyo Ham Fair.

Jack pulls the names of 10 sponsors of Champ's trip to Germany to participate in the WRTC Championships out of a jar who were the lucky winners of Yaesu hats following Champ's presentation.

Champ then donated 10 Yaesu hats to members who had donated 1,000 baht or more who were selected in a lucky draw and the meeting closed with Jack thanking Champ for his presentation and for returning the 40,000 baht he had not used on his trip.
The next RAST meeting will be on Sunday, September 2, 2018 at Sena Place Hotel.

RAST Treasurer Pornpimol, HS0VDX was one of the lucky winners of a Yaesu hat.
