Since I was young, I had seen the big white base radio in my house. I saw my father
talk on that radio a few times. I learned that it was a military type radio later on.
It might be my first inspiration that make me want to know more about radio communication,
I passed my basic class license exam and gained Call Sign "E20ZFD" in 2002.
I started to learn to carry a conversation on the radio. At first, I don't really know about
another modes rather than FM Phone, direct contact. Day by day, I got more and more
information about Repeater and Daily contact with the net operator.
After a few years, I began to feel that I need to give another modes a try.
I first picked Echolink, because I was fascinated by how this system make possible that
a small station in Bangkok can talk to small station in another part of the world via "Link" station.
When Tsunami hit Thailand, I keep listen to many links to update the situation.
I also went to help out at military airfield, after received the news from Echolink.
I spent more and more time with a few conferences such as *TA CLUB*, *HS0AC*, and
I became a member of RAST in Mid 2005. at that point, I never thought that 2 years later, I would be one of HS0AC's 2M Net operator.
One day, my friends asked me to join him in listening to the satellite downlink signal.
I once again amazed by ham radio technologies. Then I became interested in Amateur Satellite communication.
With help from my friends, I made my first contact via AO-51. And that made me want to explore the world of ham radio.
I joyed the TAMSAT group and made many contacts with ham stations both in Thailand and another countries
18 December 2005, I made my first radio contact with NA1SS, operated by expedition 12 Commander, Bill McArthur.
a week later, I took part in the 25th Asia Pacific Scout Jamboree in Thailand as a staff of E25AJ, Special station.
I presented the participants with basic satellite information and trained the chosen group to be ready for the ARISS' school contact,
My friends and I began to test a few more Digital modes, including APRS, Packet radio, and SSTV. And in Jan. 2006,
I wrote about the Suitsat-1 published in Thai amateur radio Magazine "100watts". soon after that I started to write the SSTV-related
articles for the same magazine.
Once again, I was honoured to be one of net operators for HS60A, spacial callsign,
during the Sixtieth anniversary celebrations of King Bhumibol Adulyadej's accession to
the throne in 2006
At the same time, I also enjoyed connect to *Amsat*, and *NASA* conferences on the
Echolink to listen to radio contact during the Space Shuttle Launch, ARISS School Contact,
and other events. I became friend with ham from many countries around the world, friends who share similar interests.
They welcome me with opened arms, and help answering any questions I had.
During my trip to the U.S. in 2007, I went to Steven F. Udvar-Hazy Center in Chantilly, VA. to see
the Space shuttle "Enterprise" and Oscar1's full-scale model. Later on I shared those photos on my website.
I decided to study abroad and move in the U.S. in Jan. 2008
I continued to participate in Ham radio event such as Suitsat-2 "ARISSat-1", AO-51 SSTV, and ARISS SSTV.
Unfortunately, Due to my busy schedule I had to stop writing my magazine article and stay away from ham radio.
Now, I graduated and move back to Bangkok, my hometown. Hopefully, I will have time to pick up my radio again.
I took the US Amateur Radio Exam and passed Tech. and Gen. Class on 13 December 2014 at The NBTC
during Thai's Amateur Radio Day. Then, On 24 December, I received US call Sign: KK6RCX.
Now, I'm an Amateur Extra Class License with Vanity Call Sign: AA1AF
I Finally got to upgrade my Thai ham radio license to intermediate Class on 05 February 2015.
Best of luck 73’s de E20ZFD, Karn
