The phonetic alphabet on VHF: table and practice for the SV exam
Why the alphabet in channel noise, the standard ITU/ICAO-family letter table as a practice sheet, a short aloud drill, and the link to the VHF course and free trainer — not a clone of the full course.
Alphabet attribution (B19): letter words match the list on NATO History - The NATO phonetic alphabet and restated by ICAO Uniting Aviation (International Radiotelephony Spelling Alphabet). Maritime training often labels the same family ITU/ICAO. This page is a practice aid, not a substitute for Annex 10 / Radio Regulations text.
On a noisy radio channel a vessel name without the phonetic alphabet turns into guesswork: letters smear together by ear, and you have to ask twice. That is why the alphabet shows up on the Swedish VHF exam, and it is easier to learn as a working tool than as a checklist for Friday.
In short
- The alphabet is there so a name and a call sign do not fall apart in noise.
- On the SV VHF/SRC exam, phonetics usually sit in the theory block - open your commission's PDF yourself.
- Learn it as an air tool: short sessions aloud, names and call signs, not a night of cramming "for Friday."
- Check against the standard ITU/ICAO-family table below, not a retelling from a chat.
- The full VHF course and the free trainer sit next to each other and complement each other; neither replaces the other, and neither replaces a licensed course where one is required.
Why it matters on the air
When the channel is packed and diction slips, one wrong letter changes a name. "B" and "D", "M" and "N", "S" and "F" smear easily by ear - especially with a foreign accent and an engine humming next to the microphone. The alphabet gives familiar anchors: instead of a bare letter you say a word that is harder to mix with its neighbour.
This is not bureaucracy for a tick-box. It is a way to be understood the first time: vessel name, call sign, a scrap of route where every letter matters. In a quiet cabin "you can hear it anyway." On a real channel - you cannot. That is why the exam checks the alphabet not as a military ritual, but as a skill without which radio theory stays text on paper.
Letter table (practice sheet)
Below are the 26 standard words of the International Radiotelephony Spelling Alphabet family (often: NATO / ICAO; in maritime training - ITU/ICAO). The spellings Alfa (not "Alpha") and Juliett (two "t"s) are part of the standard: that is how speakers of different languages read the words more reliably. Use the table as a trainer sheet: read aloud, cover the "word" column, and check yourself.
| Letter | Word | Letter | Word |
|---|---|---|---|
| A | Alfa | N | November |
| B | Bravo | O | Oscar |
| C | Charlie | P | Papa |
| D | Delta | Q | Quebec |
| E | Echo | R | Romeo |
| F | Foxtrot | S | Sierra |
| G | Golf | T | Tango |
| H | Hotel | U | Uniform |
| I | India | V | Victor |
| J | Juliett | W | Whiskey |
| K | Kilo | X | X-ray |
| L | Lima | Y | Yankee |
| M | Mike | Z | Zulu |
Word source: the NATO History page (The NATO phonetic alphabet) and the matching list in ICAO Uniting Aviation. If your exam PDF or textbook quotes the same family - check spelling against it; do not take a "folk" list from a forum as truth.
Å, Ä, Ö - if the name is Swedish
The Latin table above does not contain Swedish letters. In Swedish VHF/SRC courses and school cheat-sheets they usually teach them as pairs of Latin letters from the same standard: Å → Alfa Alfa (AA), Ä → Alfa Echo (AE), Ö → Oscar Echo (OE). That is a common teaching convention for the air and for theory, not a separate "Swedish NATO table." If your commission PDF or school materials say otherwise - they win; here it is only an anchor so a name with Å/Ä/Ö is not left without a spelling.
Digits and procedure words - short
For clarity on the air, digits also have agreed forms. ICAO's popular alphabet write-up explicitly notes special forms for 3 → tree, 5 → fife, 9 → niner (so they do not smear with similar sounds). The full 0-9 digit table and a full treatment of procedure words (MAYDAY, PAN-PAN, SÉCURITÉ, standard harbour phrases) are not in this guide: they live in the full VHF online course and in the course phonetics module.
The exam
In the Swedish exam frame, phonetics usually sit in the theory block next to channels, distress, and procedures. Ticket wording and "what to learn by the date" lists differ by commission and they change - so open the exact PDF of your commission yourself: a checklist from a blog or a forum does not stand in for your exam date.
How to look without panic: on the site of the authority / school through which you sit SRC/VHF, find the current theory syllabus or sample questions and mark the block on phonetic alphabet / spelling. Agency rules differ; do not copy someone else's list one-for-one. Nobody can predict what will be on your ticket tomorrow; the standard table and the habit of saying it aloud carry into both the ticket and the air.
If the goal is an operator document, not only "knowing the words," the path is wider than the alphabet: theory, air practice, exam. The layers "free try / full course / exam / certificate" are unpacked in VHF online vs free trainer.
Practice
Short sessions aloud beat a long night before the exam. A working week rhythm:
- 5-10 minutes - walk the table top to bottom, without looking at "word" for every other letter.
- 5 minutes - spell a vessel name letter by letter (yours, a neighbour on the marina, any listing). Frame: "Vessel name is Foxtrot Alfa India Romeo..."
- 5 minutes - a call sign or a mixed letter+digit string: slowly, then a little faster, without swallowing endings.
- Self-check: record yourself on the phone in a noisy kitchen or with a fan nearby - and listen: where "Mike" became "something," do another round.
- Break: the next day start not from A, but from a random letter in the middle - that breaks rote from A to Z.
Sense of the air and the ear first - the free trainer; then procedure structure and phonetics in course context - the VHF online course. An alphabet without the air stays a list; air without the alphabet stays guesswork. The order "understand the channel first, then speed up the letters" is usually more honest than the reverse.
If you are preparing specifically for the SV exam, keep the commission PDF next to this table: theory asks for the standard, practice locks the voice. Do not mix "I learned the words" with "ready for the full VHF path": the second is wider and includes procedures, channels, and the exam.
Boundaries
Not a substitute for a licensed course or a national exam where they are required. Not a full VHF course in one article: here it is phonetics and why it exists. Not legal advice and not a promise that your commission will accept any outsider's notes. The table is a practice sheet against the published standard word list; if it disagrees with the official PDF, the commission PDF and the primary regulatory texts win.
FAQ
Why the alphabet if "you can hear it anyway"?
Until you can. In noise, at distance, and with a foreign accent, letters smear - asking twice costs the crew time and nerves.
Is this the whole VHF course?
No - only phonetics and why it exists. Procedures, channels, distress, and the path to a certificate sit in the course and in the layer overview online vs free trainer.
Where should I take the words if the chat has others?
From the standard table above (NATO / ICAO family) and from your commission PDF - not from a folk list "easier to remember."
Where to practise the ear of the air, not only the letters?
The free trainer - to listen; the course - to gather procedures around the skill.
Do I need digits and MAYDAY here?
Short: the special 3/5/9 forms are noted; the full digit and procedure-word treatment is in the course, not in this guide.
How do I spell Å, Ä, Ö?
Usually as pairs: Alfa Alfa / Alfa Echo / Oscar Echo - as Swedish schools teach; check against the commission PDF.

Walk the table aloud on your own names and call signs, check the phonetics block in the commission PDF, then come back to the full VHF path: free try → online course → exam and document, if you need one.
