In rememberence of His Majesty
King Bhumibol Adulyadej
1927 - 2016

His Majesty King Bhumibol Adulyadej, HS1A, the patron of the Radio Amateur Society of Thailand (RAST), passed away at Siriraj Hospital at 3.52 pm on Thursday, October 13, 2016, it was announced by the Royal Household Bureau.
His Majesty died peacefully at the Chalermphrakiet Building of Siriraj Hospital in Bangkok and all members of the royal family were present.
His Majesty was 88 and would have been 89 years old on December 5, 2016.
The Prime Minister's Office has announced that government agencies nationwide have been ordered to fly flags at half-mast for 30 days following His Majesty the King’s death and that government officials will wear black in mourning for a year.
His Majesty the King had been presented the callsign HS1A by the Ministry of Communications at Chitrlada Palace on August 18, 1989 in a ceremony witnessed by RAST officers. Five years later, in November 1994, His Majesty placed RAST under his royal patronage.

RAST to host New Year party on January 15 at Rot Meu Mae restaurant

RAST President Jakkree (Jack), HS1FVL began announcements at the December meeting at Sena Place Hotel by thanking the team of RAST staff members who had helped the society host the 44th SEANET Convention two weeks earlier in Pattaya which was a big success.
The event was well-attended with around 150 delegates from some 18 countries while Indonesia will host the 2018 event in Jogjakarta after a unanimous vote in favour of this proposal. Next year, the 45th SEANET Convention will be held in Cambodia at Siem Reap.
For full coverage and photographs of the Pattaya SEANET Convention please follow this link which has coverage of the welcome dinner and which contains links to six other web pages covering the entire event.
After applause from the audience in appreciation for the success of the event and for the efforts put into this by the RAST organizing team, Jack invited newcomers or returnees to the RAST meeting to introduce themselves.
There were many faces, both old and new, at the December meeting, including Don Craft, HS0ZBG, Rudy, HB9MHB, John, W2YR, Mike, HS0ZIU, Fred, K3ZO, Phoom, NO6A, Chris, G3VBL, along with Ritthichai, HS7JEN and Chalermpol, HS7EI and another HS7 from Nakhon Pathom.
Next month RAST will host its New Year party and this will be at the same location as last year, which is Rot Meu Mae restaurant in the northern suburbs of Bangkok, beginning at 3 p.m. on January 15, 2017. Please click here to view the location on Google Maps.
Directions: Head north from Bangkok along Vibhavadi Rangsit Highway and after the Ngarmwongwarn Road intersection take the frontage road. Turn left into the road signposted "North Park" (2.25 km beyond Ngarmwongwarn intersection). Follow this road for one and a half kilometers to a roundabout. Exit left and after 100 metres the Rot Meu Mae restaurant will be on your right.
The party will last until around 8 p.m. and guests will be invited to pay 320 baht (the same as for buffet lunch at Sena Place) for the banquet dinner.
Those attending the December meeting were also informed that the RAST club station at the Asian Institute of Technology is suffering badly from subsidence with major cracks in the building, which had been repaired and reopened in 2014 following the severe flooding in 2011.
The station is now off the air again and RAST is looking for a new location for its club station and, if possible, it would also like to establish a headquarters office as well. We hope to publish some photographs here shortly that show the extent of the damage to the station.
Jack explained that RAST had set funds aside for this, but the society was also seeking help and soliciting suggestions as to the availability of an inexpensive plot of land of approximately one rai in area in the vicinity of Bangkok where it could build these facilities, along with erecting towers and a "shack" to operate from.
This month, the National Broadcasting and Telecommunications Commission (NBTC) has cancelled "Amateur Radio Day" following the passing of His Majesty King Bhumibol Adulyadej but Jack said that the NBTC may reschedule such an event some time next year when RAST would participate.
On December 6, several RAST representatives will be participating in an NBTC seminar to which amateur radio societies throughout the country have been invited when Jack, HS1FVL and Joe, HS2JFW will make a presentation about repeaters.
Jack also announced that later this month RAST would be proposing to the NBTC that reciprocal licence holders in Thailand whose amateur radio licences are equivalent to the Thai Advanced Class licence be eligible for a Thai Advanced Class licence, rather than an Intermediate Class licence. Hopefully there will be an update about this soon.
There is also a new date for the ARDF Championships to be hosted by RAST that were postponed from the beginning of November and now they will take place in Nong Prue, Chon Buri -- near Pattaya -- on the weekend of February 18-19, 2017. Earlier they had been rescheduled to January 28-29 but this coincides with Chinese New Year, hence the new dates in mid-February.
Finally, RAST Secretary Champ, E21EIC will lead the VEC team to host the next FCC amateur radio examination for a US amateur radio licence to be held on January 7, 2017 in Chiang Rai Province from 1 p.m. to 4 p.m. For more details click here.

The 44th SEANET Convention in Pattaya hosted by the Radio Amateur Society of Thailand under the Patronage of His Majesty the King (RAST) was a big success, being attended by some 140 delegates from 18 countries. This website has extensive and detailed coverage on a total of seven web pages which cover the entire event that took place from November 18-21 at the Discovery Beach Hotel.
Formally opening the event at the Gala Dinner on Saturday was NBTC Commissioner Gen Sukit Kamasunthorn while earlier that day delegates voted to have the 2018 SEANET Convention staged in Jogjakarta, Indonesia. Next year, the event will take place in Siem Reap, Cambodia and, for the first time, this will be organized from outside the host country with a team led by Raja, VU2KKZ.
Raja was attending the SEANET Convention in Pattaya and provided those present with a briefing and an outline of the program for the 2017 Convention and there was strong support and an eagerness to attend, as displayed during the Pattaya Convention.

A solemn November meeting

Prior to the November RAST meeting on the morning of Sunday, November 6 RAST President Jakkree Hantongkom (Jack), HS1FVL had paid homage in a bereavement ceremony to His Majesty King Bhumibol Adulyadej, HS1A-SK, the patron of RAST who passed away on October 13, 2016.
The monthly meeting was held at Sena Place Hotel following the postponement of the ARDF Championships to late January in a mark of respect to His Majesty while the upcoming SEANET Convention on the weekend of November 18-21 had dominated a committee meeting of RAST officers that was held before the main meeting began.
Visitors included Kuny Nakada, 7L1FPU (AH0BT, who is the father of Yoshiki, KH0UA).
The formal part of the meeting began with everyone standing to respect the passing of His Majesty King Bhumibol Adulyadej.
Later there was a presentation of an Icom IC-9100 transceiver that RAST had purchased from G. Simon Radio for the ground station for the ongoing JAISAT satellite project which will use the callsign HS0AJ The ground station is to be located at the Rangsit campus of Bangkok University.
Among the announcements during the meeting was that the special callsign HS70A is now being used on two metres to commemorate the passing of His Majesty King Bhumibol Adulyadej by enabling radio amateurs to express their condolences over the air between November 1 and December 31, 2016 on the amateur radio bands from every province in Thailand.
There is an online logbook of these QSOs and a summary of all contacts will be sent to the National Broadcasting and Telecommunications Commission (NBTC) which will forward the log to the Royal Palace. More details can be found at the following link:
The online log can be viewed at this link:
During the meeting plans for a micro DX-pedition to Myanmar from November 15-22 were announced when the callsign may be XZ1A with the operators being JH1AJT, Zorro, DJ9AB, Andre, W5MJ, Madison, E20NKB, JC and E21EIC, Champ.

ARDF Championships postponed

The ARDF Championships which had been planned for November 5-6 at Nong Prue near Pattaya have been postponed to the weekend of February 18-19, 2017 to respect the passing of His Majesty King Bhumiphol Adulyadej on October 13.
RAST regrets any inconvenience this may cause and will announce further details later.

RAST to host Sunday meeting at Sena Place Hotel instead

Instead, on Sunday November 6, 2016 RAST will host its November monthly meeting at Sena Place Hotel from 11 a.m. onwards and all RAST members and any amateur radio operators visiting Thailand at the time are invited to attend.

ARDF and Seanet Convention dominate October meeting

Announcements at the October RAST meeting at Sena Place Hotel, attended by some 50 members and guests, began with everyone standing for a minute of silence in respect for Sawat, HS1HQT (pictured at right) a former RAST member but now a silent key who had passed away from heart failure following the September meeting. May he rest in peace.
The upcoming ARDF Championships on November 5-6 and the SEANET Convention in Pattaya from November 18-20 will be keeping RAST busy next month and these topics dominated the announcements.
Having been the society that won the Princess Maha Chakri Sirindhorn ARDF Trophy last year, RAST has the honour of hosting the direction-finding championships this year and these will take place at Nong Prue in Bang Lamung, Chon Buri on the first weekend of next month. Nong Prue is on the outskirts of Pattaya and the municipality is located about six kilometres inland. Here is a link to the location on Google Maps satellite view and this link shows the map view.
There will be various activities and details of the event can be found here. On that Sunday there will be no regular RAST meeting at Sena Place Hotel but all members are welcome to attend the ARDF Championships at Nong Prue Municipality when food will also be available.

The RAST committee meets at Sena Place Hotel prior to the main meeting on Sunday, October 2, 2016.

As for the 44th SEANET Convention at Discovery Beach Hotel in Pattaya, the convention will begin on the evening of Friday, November 18 with a welcome dinner and there will be a gala dinner on Saturday. Details of the programme can be found here. There will be a special event station using the callsign HS44SEA which has been authorised by the NBTC Secretariat and there will also be tours to Suan Nongnooch and other attractions.
As for transport to the SEANET Convention from Bangkok, RAST will be providing minibuses which will depart regularly from both Don Muang and Suvarnabhumi airports on Friday for the Discovery Beach Hotel in Pattaya and members are welcome to avail themselves of this means of transport. Alternatively, of course, they may drive down to Pattaya or take a bus or tour bus from Ekamai or Morchit bus stations. The journey to Pattaya by car usually takes less than two hours via the Motorway (Route 7) or the Burapawithi elevated toll road (Route 34) followed by Route 7.

For some the tables at Sena Place Hotel are for enjoying the
buffet lunch while for others it makes a good workplace!

September RAST meeting

Two upcoming events in November dominated the announcements made during the September RAST meeting at Sena Place Hotel, namely the 44th annual SEANET Convention and the 2016 ARDF Championships which RAST is hosting this year.
Both events will be staged in or close to Pattaya and involve a lot of planning and RAST President Jakkree Hantongkom, HS1FVL provided an update about both events, along with making a special offer of a discount to expat members of RAST who were present at the meeting.

During the buffet lunch, there was a slide show and videos were on display that had been taken at the JARL Ham Fair in Tokyo, Japan. The event had been attended by almost 30 RAST members, including a team of 10 led by the RAST President who had helped to man the RAST booth at Asia's largest amateur radio convention and exhibition.
During the event, Jakkree took the opportunity to meet with Yaesu Musen CEO Jun Hasegawa when he sought Yaesu's sponsorship of the SEANET Convention with the donation of a transceiver to be the first prize in the lucky draw.
Jakkree said that Mr Hasegawa had approved this and had offered other items of equipment as part of the sponsorship and we will have more details on this website after they are finalised.
Introducing themselves to those present were three visitors who were attending a RAST meeting for the first time, Rolf, HB9MUQ and HS0ZMS, along with Gunther, DF2ZT and HS4YGV, Thishi.
The RAST President also said that during the Tokyo ham fair the Japanese AMSAT association (JAMSAT) had presented a satellite transponder to the JAISAT team, their counterparts in Thailand -- JAISAT being the abbreviation for "the Joint Academy for Intelligent Satellites for Amateur Radio of Thailand".
Following this announcement, Jakkree made a presentation of the transponder to JAISAT team leader Tanan, HS1JAN along with Anant, HS1GAB.

Looking ahead to November, there will be two major events beginning with the ARDF Championships on the weekend of November 5-6 when the highlight will be that the winning team will receive Her Royal Highness Maha Chakri Sirindhorn's trophy. There will be many other trophies and awards and response from amateur radio association across the country has been very good and more information can be found here.

The event will take place in Nong Prue, Bang Lamung in Chon Buri, on the outskirts of Pattaya at the Nong Prue Municipality and the RAST meeting that month will also be held there.
Meanwhile, some two weeks later, from November 18 onwards RAST will be hosting the 44th annual SEANET Convention at the Discovery Beach Hotel in Pattaya for three days.
During the meeting Jakkree offered expatriate members of RAST an opportunity to register for the convention at a discounted rate with three options:
-- to stay at the convention hotel and participate in all the SEANET events and tours for 12,000 baht;
-- to participate in all activities but without staying in the convention hotel for 8,000 baht;
-- or to just attend the SEANET gala dinner on Saturday evening for 2,400 baht.
Several members present signed up for one of these options.

Then Jakkree invited RAST Secretary Champ, E21EIC to make an announcement and there were two ARRL DXCC awards that were presented to Sakol Nakin, HS1JNB for working 100 or more amateur radio stations on CW and separately on the 15-metre band.
Tony, HS0ZDX then took advantage of Champ's presence in front of members at the meeting to announce that during the JARL Ham Fair Champ had received an award from the Wireless Institute of Australia (WIA) that recognises "excellent Single Operator achievement within IARU Region 3 in the IARU HF Championship contest." The trophy was in the name of Michael Owen, VK3KI-SK and presented at the RAST booth by Peter Young, VK3MV and a picture of the presentation can be seen below.
Champ also announced that he would be participating in a DXpedition to Bhutan with Zorro, JH1AJT and Franz, DJ9ZB where they would operate as A5A from September 8 - 17.
Following these announcements JAISAT team members Tanan and Anant made a illustrated presentation about developments in developing the JAISAT CubeSAT which included technical advances in developing components of the satellite as well as approvals from the National Broadcasting and Telecommunications Commission (NBTC) and work on the HS0AJ satellite ground station at Bangkok University's Rangsit campus.

IARU contest trophy awarded to Champ, E21EIC

The Wireless Institute of Australia (WIA) has introduced a new award that recognises "excellent Single Operator achievement within IARU Region 3 in the IARU HF Championship" contest and the honour of being awarded the first trophy goes to Chalermphol Muangamphun (Champ), E21EIC for his performance in the 2015 contest.
The trophy is issued in honour of the late Michael Owen, VK3KI-SK, a former IARU Director. Presenting the trophy to Champ at the RAST booth at the Tokyo Ham Fair is Peter Young, VK3MV representing the WIA and the IARU Region 3.
Congratulations to Champ!

Large RAST team attends the JARL Ham Fair in Tokyo

A large team of RAST officers and members attended the JARL Ham Fair at Tokyo Big Sight in Ariake, Tokyo Japan over the weekend of August 20-21 led by RAST President Jakkree (Jack) Hantongkom where the society had a booth that promoted the upcoming SEANET Convention in Pattaya.
The Tokyo Ham Fair is Asia's largest amateur radio event which last year was attended by some 36,000 visitors.
RAST has participated in this event for several years now which provides a unique opportunity for officers of the society to meet the President of the IARU Tim Ellam, VE6SH and IARU Region 3 Chairman Gopal Madhavan, VU2GMN as well as the leaders of the Japan Amateur Radio League (JARL) and top executives of Japanese amateur radio equipment manufacturers.

RAST President Jakkree (Jack), HS1FVL (seated at right) led a team totalling 27 RAST respresentatives to the Tokyo Ham Fair. This is one view of the RAST booth in the exhibition.

Advanced Class exam results
announced at August meeting

With August 7 being the day of the vote on Thailand's draft constitution, the turnout at the RAST meeting at Sena Place Hotel was somewhat lower than usual with slightly more than 30 members and guests attending.
After the buffet lunch, Bob, HS0ZCG, who had not attended a meeting for several months, along with Chong, E23HSW, and Denis, HB9TWK, introduced themselves to everyone before RAST President Jakkree (Jack), HS1FVL provided an update, beginning with the results of the recent Advanced Class amateur radio examination.
A total of 155 candidates passed the exam, he announced, and while certificates were already available they would soon receive an upgrade of their licences that will permit output power on the HF bands to be up to 1 kilowatt of power, rather than the 200 watts permitted for Intermediate Class licence holders.

RAST team of 27 to attend JARL Ham Fair

As for upcoming events, Jack also said that a team of over 20 RAST officers and members would be attending the Japan Amateur Radio League (JARL) Ham Fair in Tokyo, Japan later this month where RAST will have a booth in the exhibition.
In all 27 RAST representatives will be travelling to Tokyo to attend the event on August 20-21 and he said the RAST booth would emphasise the upcoming SEANET Convention in Pattaya -- and hopefully RAST will be able to sign up a few more delegates to the convention during the event.

Jack also mentioned the upcoming ARDF (Amateur Radio Direction Finding) Contest that the society will be hosting in Bang Lamung, just to the north of Pattaya, in Chon Buri province on the weekend of November 5-6, 2016. That month RAST's monthly meeting will also be held there (with full details to be posted here in advance of the meeting).

Champ also summarized the RAST team effort in the IARU HF Championships contest held on the weekend of July 9-10 using the special callsign E2HQ with the participation of official RAST stations located in the north, northeast, the central region and the southern part of Thailand. All together, the participating stations made a total of 2330 QSOs for a total score of 2,235,962 points.
Champ added that special T-shirts designed for this event were still available from RAST for 250 baht (some examples can be seen in the photos of the contest below with a souvenir T-shirt on sale at right during the meeting).
After that, Jack asked for donations to support an Internet connection for the HS0AC club station at AIT before concluding the meeting by inviting everyone present to the September meeting of RAST on Sunday, September 4.

RAST President Jakkree asks for donations to help fund an Internet link for the club station HS0AC.

RAST marks Thailand's National Telecommunications Day

Officers from RAST attended a formal ceremony on the morning of August 4, 2016 to mark National Telecommunications Day at the secretariat of the National Telecommunications and Broadcasting Commission (NBTC) on Soi Sailom, Phaholyothin Road.

155 candidates pass the first Advanced Class exam

The National Broadcasting and Telecommunications Commission (NBTC) has announced the results of the first Advanced Class amateur radio examination supervised by RAST and conducted on June 18 at the NBTC Secretariat Office.
A total of 155 candidates passed the two-hour exam, out of 171 Intermediate Class operators who participated, and they will be able to upgrade their amateur radio licences to Advanced Class which, among other things, allows output power on the HF bands to be up to 1 Kw.
Contratulations to all who passed. The full list of the successful candidates (in the Thai language) can be found here.

Excellent openings on six-metres during the CQWW VHF contest

Thanks to special permission from the Office of the National Broadcasting and Telecommunications Commission (NBTC) amateur radio stations in Thailand had the opportunity to operate on the six-metre band during the CQWW VHF contest over the weekend of July 16-17, 2016.
Operators, who had to register with RAST before the contest began, were rewarded with excellent DX openings to Asia and Europe when they were able to demonstrate the reach of the 50-54 MHz spectrum by working stations in over 30 countries.
There should be a report about these conditions during the August RAST meeting at Sena Place hotel by some of the operators but a glance at the spots on the DX clusters DX Summit and DX Watch provides plenty of evidence of the good conditions.
Thai stations were spotted during the contest on these clusters by radio amateurs based in a total of over 30 countries ranging from Malaysia, the Philippines and Japan in Asia, from across Russia and throughout Europe down to northern Africa with spots being made from the Canary Islands off the coast of Spain.
Within Europe itself there were spots of Thai stations on six metres from Ireland, England, France, Germany, the Ukraine, Italy and Greece, along with many other countries.
In all there were over 240 spots of Thai stations on the DX Summit cluster and most of these were made from outside Thailand on Saturday, when the opening to Europe lasted for around five hours from 03.23z to 08.54z. Propagation to Europe on Sunday was not so good with reports from stations located there spanning slightly over three hours between 06.38z and 09.50z. The majority of the spots were on CW, but there were many Thai stations worked using phone as well.
Around 20 Thai stations were spotted on these clusters with the credit for the most spots going to Champ, E21EIC who had a total of 52 spots. Next was the E2X contest station with 42 spots and third was RAST's HS0AC contest station with 36 spots on DX Summit. The next three Thai stations that were getting out well were E20QVD (25 spots), E20WXA (15 spots) and HS3ANP with 10 spots.
Congratulations to everyone in the contest and especially those stations that took advantage of the rare opportunity to put HS on six metres and demonstrate the potential for DX propagation on that band. -- summary by Tony, HS0ZDX

Big team effort in IARU HF Championship by RAST

RAST made a big team effort over the weekend of July 9-10 in the IARU HF Championship Contest with participation from all over the country and using the special event callsign E2HQ. There will be a full report about the contest activity during the next meeting of RAST at Sena Place hotel on Sunday, August 7 but these pictures hopefully give you an idea of the scope of the participation.

Over 2,000 QSOs were made during the contest on bands from 160 to 10 metres in both CW and SSB modes. The photos include information about the operators and some of the stations participating. Our thanks go to RAST Secretary Champ, E21EIC for the pictures and for helping to co-ordinate the event.

RAST takes part in Friedrichshafen Ham Fair with a booth

RAST had a booth at the Friedrichshafen Ham Fair in Germany from June 24-26 which was well attended with more than 17,000 visitors. As in previous years, RAST had a booth in the main hall and the society is most grateful to its members in Germany who supported the society by setting up and manning the booth at Europe's largest amateur radio convention.
These included Koess, HS0ZLA, Gerd, HS0ZKF and Benjamas, HS6SSE (seen at the centre of both pictures here).
According to Koess, many radio amateurs visited the booth and there were many asking how to operate amateur radio from Thailand. Staff at the booth provided them with information about this and explained the situation since Thailand is not a member of the CEPT. In addition, several visitors also decided to attend the upcoming SEANET Convention in Pattaya this coming November. More than 350 visitors signed the RAST guestbook at Friedrichshafen.

In the picture below, Benjamas is seen with Fred Laun, K3ZO and HS0ZAR (left) and John Gagen, W2YR and HS0ZDJ. Thanks to Benjamas for the photo above and to John Gagen for the picture below.

Foreigners with a Thai licence need to send an information update to RAST

During the June RAST meeting, the RAST President made an important announcement regarding the society's need to comply with a request made to it by the National Broadcasting and Telecommunications Commission (NBTC) regarding information about its members.
He explained that, according to an NBTC announcement made in 2014, all amateur radio operators in Thailand are required to be a member of an amateur radio society that is approved by the NBTC.
Jakkree said that NBTC Secretariat has asked the registrars of all amateur radio societies to provide them with a summary of their members so that the NBTC will be able to provide a searchable database online and to comply with this request and ensure that its information is up-to-date RAST would like all its expatriate members who hold callsigns in the HS0Zxx range to provide the following information and to send it in an email to or
-- a scan or copy of their passport or ID card;
-- a scan or copy of their HS0Zxx amateur radio licence;
-- a scan or copy of their RAST membership card.
RAST would appreciate it if all expat members can comply with this request as soon as possible and an email has been sent notifying all members of this request.

But, if your licence has expired, this is what you must do

In addition, for any foreign amateur radio operator with an HS0Zxx callsign whose licence has expired for a period exceeding two years but who wishes to renew their licence, they must complete this licence renewal before December 31, 2016 or else their licence will be revoked and their amateur radio equipment will immediately become illegal to own or to possess.
To renew their licence they must take the following steps:
1. Fill out a Chor.Gor.2 form and a proxy form which can be downloaded from here;
2. Provide their original licence;
3. Provide a one- or two-inch recent photograph of themselves;
4. Provide a copy of their passport;
5. Provide a fee of 500 baht to cover expenses including for a new licence, excise duties and the cost of processing this;
6 Provide a 50 baht additional payment which is the fine for allowing the licence to expire.
These documents and fees should be provided to RAST Secretary Chalermphol Muangamphan (Champ), E21EIC or the RAST Registrar, Acting 2nd Lt Neeranuch Muangamphan (JC Goi) E20NKB. Again, the deadline for this is the end of this year but the sooner action can be taken, the better.

Candidates line up before the Advanced Class exam on June 18

Over 100 candidates who are about to take the first advanced class amateur radio examination pose before the exam at the National Broadcasting and Telecommunications Commission Secretariat on Saturday, June 18, 2016.

NBTC conducts the first Advanced Class exam supervised by RAST

Thailand's regulator, the National Broadcasting and Telecommunications Commission (NBTC), conducted its first Advanced Class amateur radio examination on the morning of Saturday June 18 at its secretariat office on Phaholyothin Soi 8. A total of 171 candidates who hold Intermediate Class licences had applied to take the exam.
RAST helped to supervise the examination and the RAST President, Jakree Hantongkom, HS1FVL, and most of the society's committee members were among the candidates who, if they pass the exam, will receive additional privileges including an increase in the power limit for their HF transmissions of up to 1 kilowatt.
The following photographs capture the atmosphere and camardarie at the event and the pictures were taken by Champ Muangamphan, Pranee Nertrattana, Wanlop Tadsri, Thida Denpruektham and Ray T. Moonton and posted to Facebook.

After attending the exam to sit for an advanced class amateur radio licence, RAST President Jakkree, HS1FVL visited the HS0AC club station at the campus of the Asian Institute of Technology (AIT) where he made presentations of plaques for the CQWW VHF contest for 2015.

Presentations were made to RAST Secretary Champ, E21EIC, (seen above with Jakkree, HS1FVL) the Siam DX Group award as the winner in the Thailand Single Operator category for 50 MHz.

Jakkree makes a presentation to Damrongsak, HS8GLR who was the winner in the Thailand Single Operator in the all band category of the 2015 CQ WW VHF Contest.

Damrongsak, HS8GLR also accepted a plaque on behalf of HS3NBR/R, the winner in the Thailand Rover category. The awards were sponsored by E21EIC and E20NKB and the Siam DX Group.

When floodwater
inundated the
