Explore: Phone (Voice) Modes

Whether you just earned your Technician license or you’ve been on the air for decades, voice — or “phone” — remains the most popular way hams communicate.  Amateur radio supports several voice modes.  Each has its own character, and the one you’ll use depends on the band and the type of contact you want to make.  This guide walks you through everything from keying up on a local repeater for the first time to calling CQ on the HF bands.

FM (Frequency Modulation)

FM is the mode you’ll encounter first as a Technician. It delivers clear, static-free audio and is the standard mode on VHF and UHF repeaters and simplex frequencies. FM signals are either there or they aren’t — you won’t hear the gradual fade-in that characterizes HF. Most handheld radios (HTs) and mobile rigs operate FM by default.

SSB (Single Sideband)

SSB is the workhorse of HF voice communication. It uses your transmitter power far more efficiently than AM and occupies less bandwidth, which means more conversations can fit on a band. SSB comes in two flavors:

• LSB (Lower Sideband): Used by convention on 160, 80, and 40 meters.
• USB (Upper Sideband): Used on 20 meters and above, and on 60 meters (required by FCC rules).

SSB audio sounds a bit “tinny” compared to FM — that’s normal. Your ear adjusts quickly.

AM (Amplitude Modulation)

AM is the original voice mode and still has a dedicated following, particularly on 80, 40, and 10 meters. AM offers richer audio fidelity than SSB, but it uses more power and bandwidth. If you hear a round-table discussion with full, warm audio on 3.870 or 7.290 MHz, you’ve probably found the AM crowd.

Before You Transmit: Listen First

The single best piece of advice for any new operator — and a good reminder for experienced ones — is to listen before you talk. Tuning around and absorbing the rhythm of on-air conversations teaches you more in an hour than any manual can.

Here’s what to listen for:

• How operators identify themselves and exchange information
• The pacing of transmissions — when people key up and when they pause
• Common phrases and their meanings
• The difference between a casual ragchew, a net, and a contest exchange

Tip for the veterans: Periodically spend a session just listening. You’ll pick up on band conditions, new activity patterns, and maybe hear a new operator who could use a friendly QSO.

The ITU Phonetic Alphabet

On the air, letters can sound alike — “B” and “D,” “M” and “N,” “T” and “P” — especially through static and noise. The ITU/NATO phonetic alphabet eliminates this confusion. Memorize it. It’s the international standard, and every amateur radio operator around the world will understand it.

Your club callsign, W9AXD, is spoken as: “Whiskey Nine Alpha X-ray Delta.”

Stick to the standard. You’ll hear creative variations on the air — “Kilowatt” for K, “America” for A — but non-standard phonetics can confuse operators, especially in poor conditions or when working stations where English isn’t the primary language. Save the creativity for your QSL cards.

Your First Contact: FM Repeaters

For most new Technician licensees, the local VHF/UHF repeater is home base. Repeaters extend the range of your signal by receiving on one frequency and retransmitting on another, often from a high location.

Step by Step: Joining a Repeater Conversation

1. Program the repeater. You’ll need the output frequency, the offset (+ or −), and any CTCSS tone (also called PL tone). Check the RARA website or RepeaterBook.com for local listings.
2. Listen. Make sure the repeater isn’t in use before you transmit. Wait for a pause between transmissions.
3. Identify yourself. Key up and say your callsign: “This is [your callsign], listening.” Or simply: “[Your callsign], monitoring.”
4. Wait. If someone is available and interested, they’ll come back to you. Be patient — not every call gets an immediate response.
5. Talk. When someone responds, exchange names, locations, and signal reports. Keep it conversational.

Joining a Conversation Already in Progress

When two or more operators are already talking on a repeater, wait for a pause between transmissions — that brief moment of silence or the repeater’s courtesy beep — and give your callsign. That’s it. The stations in the conversation will acknowledge you and bring you in.

Important: Do not say “break” to join a casual conversation. The word “break” is reserved for emergencies. Simply giving your callsign during a pause is the correct way to join in.

Repeater Etiquette

• Leave pauses between transmissions. A one- or two-second gap allows other stations to join or call for help. Don’t “quick-key” back immediately.
• Keep it brief on busy repeaters. If you hear a lot of activity, keep your transmissions shorter so others can use the machine too.
• Watch the repeater timer. Most repeaters have a timeout feature (often 3 minutes) that will cut you off if you transmit too long. Keep individual transmissions shorter than the timeout.
• Identify every 10 minutes and at the end of your contact — it’s FCC rules, not just etiquette.
• Avoid controversial topics. Politics and religion tend to generate more heat than light on the air. Remember that anyone — including new hams, kids, and non-hams scanning the bands — may be listening.

Simplex Contacts

Simplex means both stations transmit and receive on the same frequency — no repeater involved. It’s a direct radio-to-radio contact. Simplex is great for local communication and is essential during emergencies when repeaters may be overloaded or down.

The national FM simplex calling frequency is 146.520 MHz on 2 meters. This is the frequency to call on if you’re looking for a simplex contact. Once you establish contact, it’s good practice to move to another simplex frequency to keep 146.520 clear for others.

On 70 cm (UHF), the national calling frequency is 446.000 MHz.

Simplex is also a great way to test your actual station coverage without the boost of a repeater. Try it — you may be surprised how far (or how short) your signal reaches.

Getting on HF: SSB Voice Contacts

Once you upgrade to General or Extra, the HF bands open up a world of long-distance communication. Making voice contacts on HF with SSB is one of the great thrills of amateur radio — today you might talk to a station in Texas, tomorrow one in Germany.

Where to Find Phone Activity

Each HF band has designated phone segments. Here are the most popular ones for General class operators (frequencies in MHz):

Note: Extra class operators have access to additional segments at the lower edge of each phone sub-band. Always check a current ARRL band chart — download one free at arrl.org/band-plan.

Technicians: You have SSB voice privileges on 10 meters (28.300–28.500 MHz, USB) at up to 200 watts PEP. When the band is open — especially during the current solar cycle peak — you can work stations hundreds or thousands of miles away. Don’t overlook this!

Calling CQ

CQ is the general call meaning “I want to talk to anyone who’s listening.” It’s how most HF contacts begin. Here’s the formula:

For example:

Tips for calling CQ:

• Before calling, listen on the frequency for a few seconds to make sure it’s not in use. Then ask: “Is this frequency in use? This is [your callsign].”  Repeat two-three times, pausing to wait for a response before calling CQ.
• Keep your CQ at a moderate pace and moderate length — roughly 20–30 seconds. If you call CQ for two minutes straight, operators will tune past you.
• Repeat two or three times, then listen. If no one answers, try again. If you still get no response after a few tries, move to a different frequency or try a different band.
• Speak clearly and at a normal pace. Rushing makes you harder to copy.

Answering a CQ

Answering someone else’s CQ is often easier — and less nerve-wracking — than calling your own. Here’s how:

For example, if you hear W1XYZ calling CQ:

Give the other station’s callsign once, then your callsign once with phonetics. Keep it short — they’re listening for a callsign, not a speech. If you aren’t heard the first time, wait until they finish another CQ cycle and try again.

The Basic QSO: What to Say

Once you’ve made contact, the first exchange typically follows a familiar pattern. Here’s what to cover:

1. Signal report — How well you’re hearing the other station (see the next section).
2. Your name — First name is standard.
3. Your location (QTH) — City and state, or grid square.
4. Station description — What rig you’re running, how much power, and what antenna. Hams love talking about equipment.

After the basics, the conversation can go anywhere — the weather, antennas, other hobbies, whatever interests you. This kind of extended conversation is called a ragchew, and it’s one of the great pleasures of ham radio.

Wrapping up: When you’re ready to end the contact, let the other station know:

“73” means “best regards” — it’s a classic ham radio sign-off. Note: it’s just “73,” not “73s.” The plural is already built in to the original meaning.

Signal Reports: The RS System

On phone (voice), signal reports use two numbers: Readability and Signal Strength, or “RS.” (The third digit, Tone, applies only to CW.) A perfect phone report is “five nine” (RS 59).

Readability (R)

Signal Strength (S)

You can reference your receiver’s S-meter for the signal strength number, and use your own judgment for readability. Many operators give “59” almost reflexively, especially during contests. Try to give honest reports — the other station may genuinely want to know how they’re getting out, especially if they’re testing a new antenna or adjusting their setup.

On FM repeaters, the RS system doesn’t apply the same way because FM is either clear or not. Instead, you’ll hear terms like “full quieting” (strong, clean signal — no background noise) or “a little noisy but readable.” If a station is hitting the repeater but their signal is scratchy, you might say “you’re into the repeater but a bit noisy.”

Nets: Organized On-Air Meetings

A net is a group of stations that meet on a specific frequency at a scheduled time, led by a net control operator (NCO). Nets are an excellent way for new operators to get on the air in a structured environment.

Types of nets include:

• Club nets — like RARA’s own nets, where members check in and share news.
• Traffic nets — part of the National Traffic System (NTS) for relaying formal messages.
• Skywarn/Emergency/ARES nets — activated during severe weather or emergencies.
• Ragchew nets — informal, just for socializing.
• Specialty nets — for particular interests like QRP (low power), antennas, or DX.

How to Check In to a Net

1. Tune to the net frequency before the scheduled start time and listen.
2. The NCO will open the net and call for check-ins, often by call sign suffix, location, or other grouping.
3. When it’s your turn, give your callsign clearly using phonetics.
4. The NCO may ask if you have any traffic (messages) or announcements.
5. Follow the NCO’s instructions — they’re managing the flow of the net.

Nets are a low-pressure way to practice your on-air skills and get to know other operators. Check the RARA calendar for our net schedule.

Working DX (Long-Distance Contacts)

Working DX — making contact with stations in other countries — is one of the most exciting aspects of HF operating. Here are some guidelines:

• Be patient. A rare DX station may have a large pileup (many stations calling at once). Listen to the DX station’s pattern before calling.
• Give your callsign once, maybe twice. Repeating your callsign over and over just adds to the chaos.
• Listen for instructions. The DX station may be working “by the numbers” (calling specific call areas) or working split (listening on a different frequency from where they’re transmitting). If they say “listening up 5,” they’re listening 5 kHz above their transmit frequency.
• Keep the exchange short. A DX contact is typically signal report and a “thank you” — nothing more. Save the ragchew for stations who aren’t running a pileup.
• Don’t be a “policeman.” If someone is operating poorly in a pileup, let it go. Adding to the QRM with on-frequency comments only makes things worse.

Tip: Websites like DX Summit and DXWatch provide real-time DX spotting so you know when rare stations are on the air.

Contests

Contests are timed on-air competitions where operators try to make as many contacts as possible. They’re fast-paced and a great way to fill your log, improve your operating skills, and test your station. Contest exchanges are brief — typically callsign, signal report, and a piece of exchange information like your state, CQ zone, or a serial number.

A typical contest exchange sounds like:

That’s it — the whole contact takes 15–30 seconds. Don’t be intimidated. Contesters are friendly and want to work you. The ARRL, CQ Magazine, and other organizations sponsor contests throughout the year. The ARRL website lists the full contest calendar at arrl.org/contest-calendar.

For old timers: If you’re not a contester, please don’t get frustrated when contests are happening. It’s a weekend or two — maybe tune to a quieter band or take the opportunity to work on your antenna project!

Microphone Technique

Good audio starts with how you use your microphone. Poor mic technique can make even the best radio sound terrible.

• Distance matters. Keep the mic about 2–4 inches from your mouth, slightly off to one side. Talking directly into the center of the mic causes “popping” on plosive sounds (P, B, T).
• Speak across the mic, not into it. This reduces breath noise.
• Use a normal speaking voice. Don’t shout. If you need more signal, turn up the power — not your voice. Over-driving your mic creates distorted, splattered audio that’s hard to copy and interferes with adjacent frequencies.
• Set your audio levels properly. On SSB, use your radio’s ALC (Automatic Level Control) meter. Occasional peaks into the ALC zone are fine, but if the ALC is slamming to the right on every syllable, your audio is over-driven.
• Monitor your audio if your rig has a monitor function. If not, ask other stations for honest audio reports.
• Reduce background noise. Turn off fans, TVs, and other noise sources when you’re operating. The other station doesn’t want to hear your TV in the background.

Overcoming Mic Fright

Mic fright is real, and it’s completely normal. Even experienced public speakers can freeze when they key up a radio for the first time. Here are some strategies:

• Practice off-air. Rehearse a basic QSO at home. Write down what you’ll say for your first few contacts and keep the notes in front of you.
• Start with a friend. Arrange a scheduled contact with an Elmer or club member on a quiet simplex frequency. A private, low-pressure first contact builds confidence fast.
• Check in to a net. All you have to do is give your callsign. The net control station handles the rest.
• Remember: everyone was new once. Hams are overwhelmingly welcoming to new operators. If you stumble over your words, nobody cares — they’re just glad you’re on the air.
• There’s no “wrong” thing to say (within FCC rules). If you forget a Q-signal or a procedural word, just use plain English. The point is communication.

Common Q-Signals and Abbreviations

While Q-signals originated in CW, several are commonly used in voice conversations too. Here are the ones you’ll hear most often:

FCC Rules to Remember

A few key FCC regulations apply every time you key the mic:

• Identify your station with your callsign at the beginning of a contact, every 10 minutes during a contact, and at the end. You can use phone (voice) or CW for identification.
• Use minimum power necessary to maintain the contact. Don’t run a kilowatt to talk to someone 5 miles away on 20 meters.
• No broadcasting. Amateur radio is for two-way communication, not one-way transmissions to a general audience.
• No music. You cannot transmit music over amateur radio (with very narrow exceptions for space station retransmissions).
• No business communications. You can’t use ham radio to conduct business or for any communication in which you have a financial interest.
• No obscene or indecent language.
• Third-party traffic rules apply when letting a non-licensed person speak on your radio. You must maintain control of the station and identify. Not all countries permit third-party traffic — check before handing the mic to a visitor during a DX contact.

Tips for Experienced Operators

Even if you’ve been on the air for years, there’s always room to sharpen your operating:

• Elmer a new ham. Schedule a contact with someone who just passed their exam. Walk them through their first QSO. There’s no better way to give back to the hobby.
• Get honest audio reports. Ask a trusted friend to critically evaluate your signal. Many stations unknowingly transmit with distorted, hummy, or over-processed audio for years because nobody tells them.
• Try a new mode or band. If you always operate 20 meters, try 17 or 12. If you’ve never worked AM, find the AM window on 75 meters some evening.
• Brush up on split operation. If you struggle with pileups, practice working split. It’s a skill that improves with repetition.
• Slow down for weak stations. If someone is having trouble copying you, speak slower and use shorter transmissions — don’t just turn up the power.
• Keep a log. Even though the FCC no longer requires it, a log is invaluable for tracking contacts, confirming QSLs, and qualifying for awards.
