What Is Shortwave Radio Good For? Uses and Listening Tips

The short answer

Shortwave radio is mainly good for listening to distant stations without relying on the internet, phone networks or local infrastructure. Signals on these frequencies can be refracted back to Earth by the ionosphere, so a modest receiver and a wire antenna can sometimes pick up broadcasts from other countries and continents. It is also a low-cost way into a hobby that mixes electronics, geography and a bit of space weather.

Shortwave is not a replacement for FM, streaming or podcasts. Reception varies with time of day, season and solar conditions, and audio quality is usually lower than local FM. Its value lies in reach and independence rather than convenience.

What you can hear

Typical shortwave content includes:

• International broadcasters. Government and non-profit stations transmit news, music and cultural programs, often in several languages. Which broadcasters remain active changes over the years, so check a current schedule rather than relying on an old list.
• Religious and community broadcasting. A large share of shortwave transmissions are religious programs in many languages.
• Time and frequency stations. Some stations transmit time signals; in North America, WWV on frequencies such as 5, 10 and 15 MHz is a well-known example.
• Utility traffic. Aviation, maritime and other services use HF. Much of it is voice, and some is digital data that needs decoding software (see digital mode identification).
• Amateur radio operators. With the right mode setting you can hear hams talking to each other. See the difference between shortwave and ham radio for how this differs from broadcast listening.
• Unusual signals. Beacons, tones and occasional mystery transmissions attract a dedicated group of listeners.

Does anyone still use shortwave?

Yes, though fewer people than in the past. Broadcasters have reduced or ended some services, and many audiences moved online. Shortwave is still used by some international broadcasters, by hobbyists, by amateur radio operators, and by some aviation, maritime and government services. In regions where internet access is limited or restricted, radio can remain an accessible way to receive information, though availability depends heavily on the country and the broadcaster.

Emergency and outage use

A battery-powered receiver does not need the internet or a cell network to receive a broadcast. That makes a portable radio a reasonable item for a preparedness kit. A few cautions:

• Local AM and FM stations are usually the most reliable source of local emergency information. Shortwave is more useful for distant or international information.
• Shortwave is receive-only on ordinary radios. Two-way communication needs a licensed service such as amateur radio (see ham radio for survival).
• Test the radio and keep spare batteries before you need it.

Shortwave as a hobby

Listening for fun is often called SWLing (shortwave listening). Many listeners go further into DXing, which means trying to log faraway or hard-to-hear stations. Some broadcasters will confirm a correct reception report with a QSL card or e-mail, which some listeners collect. Others experiment with antennas, receivers and software-defined radios, or build their own, as covered in our guide to building a shortwave radio receiver.

What a good first receiver looks like

There is no single best radio, but useful features for a beginner include:

• Coverage of the main shortwave range, ideally with direct frequency entry by keypad (see the shortwave frequency range).
• A telescopic whip antenna plus an external antenna jack.
• Single-sideband (SSB) mode if you want to hear hams on HF and some utility stations.
• Preset memories and a clear display.
• Reasonable selectivity, which helps separate crowded stations.

Prices and models change, so read recent reviews and user reports before buying. A software-defined radio or an online receiver can also let you sample shortwave before spending money.

Getting started listening

1. Use UTC. Broadcast schedules are generally published in Coordinated Universal Time, so set a clock to UTC.
2. Check a schedule. Find a current schedule for the time and region you want to hear, and tune to a listed frequency.
3. Pick the band for the time of day. Higher bands tend to work better in daylight and lower bands at night, as described in how far a shortwave radio can reach.
4. Get away from noise. Switching power supplies, LED lighting and computers can create interference. Try battery power and a spot away from electronics.
5. Add a wire antenna. Even a longer length of wire connected to the antenna jack often improves weak signals compared to the built-in whip. Follow the radio manual for connection.

Limits

• Conditions change from hour to hour.
• Static, fading and interference are normal.
• Many once-active stations are gone, so schedules need checking.
• Transmitting is not possible with a receiver, and doing so requires a license in most countries.

What can I listen to with a shortwave radio? News, music, religious programs, time signals, aviation and maritime voice traffic, and amateur radio conversations, depending on the receiver and conditions.
