ขอบคุณครับที่ร่วมตอบ
ขออภัยที่มาขอบคุณช้า ไม่ได้เข้าฟอรั่มมานานครับ

แต่จากที่เตรียมตัวสอบครั้งที่ผ่านมา กับดูวงจรพิ้กซี่ ดูเหมือนว่าA1A จะใช้พาหะรวมกับออดิโอของStraightkey หรือกรณีPuddle ก็ต้องใช้Electronic keyมาประกอบ ดูแล้วน่าจะเป็นสัญญาณAM นะครับ แตไม่แน่ใจว่าเข้าใจถูกหรือไม่

ส่วนตามข้อสอบเรื่อง ความถี่A1Aปกติ พบคำตอบแล้วครับว่า ใช้คำว่าต้นแบนด์เป็นหลัก ได้คำตอบจากคลิปติวขั้นกลางมาครับ ว่าให้ดูแถวต้นแบนด์ คำตอบเลยเป็นความถี่ต่ำสุดของแต่ละแบนด์ในข้อสอบครับ

แต่ถ้าดูตามแบนด์ของIARU หรือITU เหมือนจะCWได้ตลอดย่านครับ ยกเว้นที่กำหนดให้ใช้อย่างอื่นได้ อันนี้ก็ไม่แน่ใจเหมือนกันอยากให้รุ่นพี่ๆช่วยยืนยันหรือแก้ไขให้ด้วยครับ เพิ่งสอบเสร็จวิชายังร้อน ขอปล่อยของหน่อยนะครับ^^

Legal / The deadline for renewing licenses - why doesn't RAST hire someone?!?
« Last post by hs0zfe on January 27, 2017, 12:27:48 PM »
Hi All


I'm deeply upset about the recent experience regarding this deadline. Am overseas and cannot appear in person to apply.


Sent them a EMS letter, which has been ignored by the NTBC.


Personally, I'm convinced that it would pay someone a living wage helping foreign hams with licensing etc. I honestly do! Paying a few thousand THB for such a service would be pleasant vs the alternative.


Rant over.

Not only is the advanced licence in the Thai language, but it is only open to Thai citizens.


Foreigners in Thailand only have the option of a reciprocal licence - the HS0Zxx licence we all have. Or they can apply for Thai citizenship, which is difficult to qualify for, and takes a long time to get.


Best regards and 73,

Denis,
check your Thai radio licence first. There you will find the power output you can use. As far as i know the intermediate licence is limited to 200W, but even that depends on the radio you use. I use a IC-718 and my licence is limited to 100W as the radio is not producing more power.
Using an 1 kW amplifier is therfore ilegal.
The only chance to run 1 kW is the new Thai high power licence, but as far as I know the only chance to get it is to make a new radio examination in Thailand. And that's maybe in Thai language only.!
Please don't do any ileagal things, because if you will be caught maybe all HS0Zxx farangs have to suffer from that.
