How to make your first HF contact

Answer somebody else first. Calling CQ into an empty band is the hardest possible start.

The short answer

The easiest first HF contact is answering a CQ on 40 metres in the evening or 20 metres in the afternoon. Listen until you find a clear station calling, wait for them to finish, say your callsign twice phonetically, then exchange signal report, name and location. The whole contact takes under two minutes.

Easiest band, daytime: 20 m
Easiest band, evening: 40 m
License needed: General
Minimum exchange: Call, report, name, QTH
Typical contact: 2 to 10 minutes
Power that works: 100 W is plenty

The first HF contact is the moment the hobby stops being theoretical. It is also the moment most new General class operators stall, because a band full of strangers sounds like a room you were not invited into. It is not. HF operators actively want to work new callsigns, and a new General is the most welcome signal on the band.

The trick is to stop trying to call CQ. Calling into an empty band with an unfamiliar callsign, an antenna you are unsure of and a radio you have owned for a week is the hardest version of the task. Answering somebody who is already calling removes every uncertainty except your own transmission.

This page gives you the band to try, the exact words to say, and what to check when nobody answers.

Pick the right band for the time of day

HF propagation changes through the day because the ionosphere changes. You do not need to understand it yet, only to be on a band that is open. Getting this one choice right is the difference between a busy band and silence.

Band choice

Where to find conversations, by time of day

Band	Best time	Typical range	Character
80 m	Night	Under 500 miles	Regional rag chews and nets, noisy in summer
40 m	Evening and night	100 to 1500 miles	The most reliable band in the country, always has activity
20 m	Daylight, all year	Worldwide	The main long-distance band, busiest in the afternoon
17 m	Daylight	Worldwide	Quieter and more relaxed than 20, no contests allowed
15 m	Daylight, good years	Worldwide	Excellent when solar activity is high, dead when it is not
10 m	Daylight, good years	Worldwide or local	Spectacular at solar maximum, and often empty otherwise

For a first contact, try 40 metres after dinner or 20 metres in the middle of the afternoon. Both nearly always have something happening. The HF propagation basics guide explains why.

Listen first, for longer than feels necessary

Tune slowly across the phone portion of the band with the filter wide. You are listening for a station calling CQ that is loud, clear and speaking at a comfortable pace. Skip anybody who is weak, anybody working a pileup, and anybody running a contest exchange. You want an ordinary operator having an ordinary conversation.

Stay inside your license privileges. A General cannot use the bottom of the phone segments, and the license privileges by class chart has the exact edges.
Listen through a full exchange before you transmit. You will hear the pattern and you will hear whether the caller is friendly.
A station saying "CQ, CQ, CQ, this is W1XYZ" is looking for anybody. That is your contact.
A station saying "CQ DX" wants distant stations only, so leave that one alone for now.
If you hear a net, listen to the whole thing. Nets have a controller who will invite check-ins, which is an easier first transmission than a cold call.

The script

A complete first contact, word for word

1
Wait for them to finish and say your callsign twice
Phonetically, slowly. "Kilo X-ray Zero Alpha Bravo Charlie, Kilo X-ray Zero Alpha Bravo Charlie." Then stop and listen. Do not add anything else on the first call.
2
When they come back, confirm and give the basics
"Thanks for coming back. You are five nine into Colorado. My name is Glen, Golf Lima Echo November, and I am in Denver. How copy?" That is a complete transmission and nothing more is required.
3
Answer whatever they ask
They will ask about your radio, your antenna and how long you have been licensed. "This is my first HF contact" is a sentence that gets you a warm reception every time.
4
Give a real signal report
Readability one to five, strength one to nine. Five nine means perfectly readable and very strong. If they are weak and scratchy, say three three and mean it. The RST signal reports reference explains the scale.
5
Close cleanly
"Thanks for the contact and for my first one on HF. Seventy three, this is KX0ABC, back to you." Seventy three means best regards. Never say seventy threes.
6
Log it
Date, time in UTC, band, mode, their callsign, both signal reports. See logging and confirming contacts for how that turns into awards later.

When nobody comes back

This happens, and it is almost never about your voice. Work through it in this order, because the order matters.

Check you actually transmitted. Does the meter show forward power? Does the SWR reading look sane? A radio in the wrong mode or a tuner not in line produces silence at both ends.
Check your SWR on that exact frequency. An antenna resonant 200 kHz away can present a match your radio will not run into. A Surecom SW-102 digital VHF/UHF SWR meter inline meter or a NanoVNA H4 vector network analyzer answers this in seconds. Read reading SWR and fixing a bad match.
Try a stronger station. If the caller is barely readable to you, you are probably barely readable to them, and everyone else answering is louder.
Wait for a gap. Several stations often answer at once. Being polite and calling again after the pileup clears works better than transmitting over people.
Change bands, not power. Going from 100 W to 400 W is one S unit. Moving from a closed band to an open one is twenty. Power is the least useful lever you have.
Check for common mode current. If your SWR changes when you touch the radio, or the computer misbehaves on transmit, RF is on the outside of the coax. See common mode current and RF in the shack.

Safety

RF exposure: you must evaluate your own station

The FCC requires every amateur station to perform a routine RF exposure evaluation and to keep the result. The categorical exemption that used to excuse amateurs by power level alone was removed, so there is no wattage below which you can simply assume you comply.

Radio frequency energy at close range is a real hazard, not a paperwork exercise. Transmitting at power into an antenna a few feet from a person, especially on the bands between 30 and 300 MHz where the exposure limit is at its strictest, can exceed the maximum permissible exposure for an uncontrolled environment.

Nothing on this page evaluates your station. The answer depends on your frequency, your power at the antenna, your antenna gain, your duty cycle and how close people actually get. Run the numbers for your own installation.

Common questions

Questions people ask about this

What do I say if I get nervous and forget the script?

Say your callsign and stop. That is a complete and correct transmission, and the other operator will carry the conversation from there. Experienced operators are used to new voices and will prompt you with easy questions about your radio and antenna. There is no procedure you can get so wrong that anyone minds.

Do I need to give a signal report if the band is noisy?

Give an honest one. Reporting everybody as five nine is a habit from contesting where the exchange is a formality, and on a conversational contact it removes the only feedback the other station gets. If they are readable but weak, five three or four five is a useful report and nobody takes offence.

Is 100 watts enough for worldwide contacts?

Comfortably. A 100 W station with a wire antenna at reasonable height works the world regularly, and the antenna matters far more than the power. Doubling power gains one S unit. Getting the antenna ten feet higher or into the clear can gain several. Amplifiers solve a real problem, but it is a problem you meet much later.

Which mode should I try first, SSB or CW?

SSB voice, because you already know how to talk. CW takes months to become conversational and rewards the effort with a mode that works when voice does not, but it is not a first-contact mode. FT8 is the third option and is easier still, though it exchanges almost no information and teaches you little about operating.

Can a Technician make an HF contact?

Yes, on a limited basis. Technicians have CW privileges on 80, 40 and 15 metres, plus voice and digital privileges on part of 10 metres. When solar activity is high, 10 metre SSB is genuinely usable and many Technicians make their first long-distance contacts there. For full HF voice access you want the General license.
