" SPARK เป็นคำที่เรียก พนักงานวิทยุประจำเรือสินค้า แปลเป็นไทยง่าย ๆ คือ นายวิทยุ "
หลายครั้งที่ผมถูก ถาม ( แซว ) จาก SPARK ของ เรืออื่น ๆ ว่า ความถี่ VHF ความถี่อื่นในเมืองไทยนั้นไม่พอใช้แล้วหรือ ถึงได้เอา ความถี่ VHF Marine Band มาใช้บนฝั่งกันเสียจน บางครั้ง รบกวนไปถึงกลางทะเล
คำพูดสั้น ๆ แต่ได้ใจความนี้เป็นที่มา ที่ผมต้องกลับมาหาข้อมูล เรื่อง ความถี่ VHF และ ก็นำมาแจ้งแถลงไข ให้เพื่อน ๆ พี่ ๆ รวมทั้งผู้เกี่ยวข้อง รับทราบ
VHF Marine Radio Frequencies
Important Note
Anyone who intends to listen to radio transmissions should be aware that licence is not required for a radio receiver as long as it is not capable of transmission as well.
However, although it is not illegal to sell, buy or own a scanning or other receiver in the UK, it must only be used to listen to transmissions meant for GENERAL RECEPTION. The services that you can listen to include Amateur and Citizens' Band transmissions, licensed broadcast radio and weather and navigation broadcasts.
It is an offence to listen to any other radio services unless you are authorized by a designated person to do so. This means that it is illegal to listen toanything other than general reception transmissions unless you are either a licensed user of the frequencies in question or have been specifically authorised to do so. Also if communication is overheard it is illegal to tell a third party what you have heard or profit from the information.
The above is only a summary of the relevant guidance note on the OFCOM website issued some time ago by the now defunct Radio Communication Agency but should still be considered valid. Should anyone have any doubt about the legality of radio reception they should visit the OFCOM website for further clarification and read the information note in full or contact OFCOM
SOLENT AREA VHF MARINE RADIO FREQUENCY LIST
Notes:
1 A simplex channel is where the A and B frequencies are the same. Both stations use the same frequency. If both stations are in range the conversation will be heard.
2 A duplex channel is where the A and B frequencies are different. The two stations use different frequencies. Only one side of the conversation will be heard.
3 With duplex channels, the ship station transmits on the lower (A) frequency and listens on the upper (B) frequency. The shore station transmits on the upper (B) frequency and listens on the lower (A) frequency.
4 Many of the duplex channels which were used for public correspondence are now being allocated for other services such as weather forecast broadcasts and AIS due to the increased use of mobile telephones and satellite services.
5 Some marine traffic may use other frequencies e.g. hire radios for special events and company private channels.
6 All frequencies in MHz.
7 For completeness USA channels are shown, 109 to 119 are actually duplex channels, but are used as simplex channels in UK.
8 Channels marked xx have no marine channel designation in UK, and the users may use their in house channel numbers.
9 At times of enhanced radio propagation usually during the summer months when high pressure systems dominate the weather ranges in excess of the typical expected line of sight are possible. Since most international channels are shared with other ports other ports maybe overheard from the Solent area i.e. Le Havre Port on Channel 12.
10 The information listed here is a compilation of information already in the public domain. The accuracy of the information cannot therefore be guaranteed or considered verified.
11 The information listed below is for information how the VHF Marine is organised and not a recommendation or incitement to listen to any transmissions that are not for general reception.
12 Generally international channels are Ch01-28 and Ch60-88 it is unlikely that transmissions for general reception will be found outside this range.

ผมจะไม่บอกนะ ว่า ความถี่ไหน หน่วยงานไหน ใช้งานกันบ้าง เพียงแต่ แจ้งให้ทราบว่า
1. ความถี่ ที่เขาใช้กันนั้นเป็นความถี่สากล ที่ชาวเรือทั่วโลกใช้งานกัน
2. เครื่องที่ชาวเรือเขาใช้กันนั้น เรียกว่า เครื่อง VHF Marine Band
3. ช่อง ความถี่ แต่ละช่อง ถูกกำหนดความถี่ FIX ไว้ ไม่สามารถ ดัดแปลง แก้ไข Program ใหม่ได้ พูดง่าย ๆ FIX ตายตัว ยิ่งกว่า เครื่องสังเคราะห์ประเภท 2
4. กำลังส่งที่ ใช้งาน กัน HI ไม่เกิน 25 วัตต์ LOW อยู่ที่ 1 วัตต์ แถม บางช่อง ถูก Lock ให้ส่ง Low
" กำลัง ส่ง 25 วัตต์ อากาศ เปิด ๆ หน่อย เคยติดต่อกันได้ ระหว่าง เรือ ที่อยู่ Singapore กับ หน้า Bangkok Bar สมุทรปราการ แถม บางที ยังคุยกับเรือ ที่ อยู่ ปลายแหลมญวน ได้ด้วย "
คำถาม " กำลังส่ง 50 วัตต์ มันจะส่งไปได้ไกล ถึงไหน หนอ ? "
ฝาก เพื่อน ๆ , พี่ , รวมทั้ง กทช. และ ผู้เกี่ยวข้อง ช่วยด้วยเถิดครับ
