USB SDR receiver
A “dongle” that plugs into your computer. With a simple antenna you can hear aircraft, ships, weather satellites and radio amateurs. No paperwork at all.
Step 5
The paperwork in Spain, your nearest radio club, the year’s key dates and everything you need to know before you start.
If you’ve caught the bug
Use the web receivers on the Listen page. If you’d like your own, a USB SDR receiver costing around €30-40 and some free software turn your computer into a radio that can hear almost anything.
It’s the quickest way to learn. The URE (Unión de Radioaficionados Españoles, the Spanish national society; website in Spanish) has sections all over Spain, and many clubs run courses for the exam.
There are questions on basic electricity and radio, regulations and operating practice. When you pass you get the HAREC certificate, which is valid in much of Europe.
With the certificate, you apply to the Ministry for your amateur radio authorisation, which assigns you your call sign (something like EA4XYZ). That’s your “name” on the air.
To have your own equipment at home, you apply for a station licence with a description of your antennas and equipment. And then: “CQ, CQ…”.
Amounts and conditions according to the URE guide (in Spanish) and Order IET/1311/2013 (in Spanish). Check them before paying: fees can change.
A “dongle” that plugs into your computer. With a simple antenna you can hear aircraft, ships, weather satellites and radio amateurs. No paperwork at all.
The classic first radio once you’re licensed: you talk to people in your area and, through repeaters, across your whole region. Ideal for the clubs’ weekly nets.
For the shortwave bands. Many people start by buying second-hand at radio rallies and putting up a wire dipole on the balcony or roof terrace.
Prices are approximate. Ask at a club before buying: there’s nearly always someone who’ll let you try theirs.
The official procedures are on the Ministry for Digital Transformation website (in Spanish). Always check the current requirements there.
Radio with no exam
Before amateur radio, or instead of it, there are two ways to talk on the radio with no exam or licence: Citizens Band (CB-27) and PMR446 walkie-talkies. Lots of radio amateurs started out this way.
A band set aside so that anyone can talk on the radio for fun, around 27 MHz. In Spain it has been common use (uso común) since 2015: you don’t need an exam, a licence or a call sign. An approved radio is all it takes.
Amplifiers or anything exceeding that power are not allowed, nor are repeaters, satellite links, connecting it to the telephone network or transmitting a continuous carrier.
The walkie-talkies sold in shops and supermarkets. They work on 446 MHz, with 0.5 W and a fixed antenna, also with no licence. Their range is short: from a few hundred metres in town to a few kilometres in open country.
| Feature | PMR446 | CB-27 | Amateur radio |
|---|---|---|---|
| Exam and licence | No | No | Yes |
| Frequencies | 446 MHz | 40 channels on 27 MHz | Dozens of bands, from long wave to microwaves |
| Power | 0.5 W | 4 W (12 W on SSB) | Much higher, depending on the band |
| Typical range | Your neighbourhood | Your local area; sometimes other countries | The world and space |
| Call sign | No | No | Yes, official |
CB sits right next to the 10-metre amateur band, so it behaves the same way: it’s nearly always local, but in the good years of the solar cycle you can hear stations from other countries. Listen to CB now on the Twente receiver.
Sources: common use of the spectrum (Ministry for Digital Transformation) (in Spanish) and Order IET/614/2015 (in Spanish) (note UN-3 of the National Frequency Allocation Table, Cuadro Nacional de Atribución de Frecuencias), which repealed the old CB-27 rules that required a licence and call sign. Checked on 1 November 2026.
Before you buy anything
The golden rule: listening is free; to transmit you need the right equipment and, outside CB and PMR446, your licence. A cheap walkie-talkie doesn’t give you permission to talk on any frequency you like.
| I want to… | Licence? | With what |
|---|---|---|
| Listen to radio amateurs, CB, broadcast stations | No | A web receiver, a USB SDR receiver or any receiver |
| Talk to my family or on a day out | No | Approved PMR446 walkie-talkies (0.5 W, fixed antenna) |
| Talk on Citizens Band | No | An approved CB-27 radio (max. 4 W, 12 W on SSB) |
| Transmit on 2 m and 70 cm, repeaters, satellites | Yes | An amateur radio (Baofeng, Quansheng, Yaesu…) and your call sign |
| Talk on police, marine, aviation or business frequencies | Never | Not allowed with any amateur equipment |
Any equipment that transmits must have its conformity assessment (CE marking). And even if a receiver picks up everything, communications not intended for the public (emergency services, private conversations) are protected by the secrecy of communications (Article 18.3 of the Spanish Constitution): you don’t listen to them on purpose, and you never pass on or use what you hear.
The Baofeng UV-5R and its siblings are the best-selling amateur handhelds in the world thanks to their price (around €20-30). They cover the 2 m and 70 cm bands and quite a lot more. That has a good side and a bad side:
Listening with it. And, with your amateur licence, transmitting on the amateur bands (144-146 MHz and 430-440 MHz).
Using it without a licence “like a walkie-talkie”: it isn’t a PMR446 (more power and a removable antenna). Nor transmitting outside the amateur bands, even if it technically can.
Reviews agree that its receiver gets overloaded near powerful antennas and that its transmitter produces spurious emissions. Germany banned its sale in 2021.
As a cheap first radio for learning to program channels, listening to repeaters and making your first contacts once you’re licensed.
| Radio | For | Licence | Approx. price | Pros / cons |
|---|---|---|---|---|
| USB SDR receiver (RTL-SDR type) | Listening to almost everything from your computer | No | ~€35-45 | The cheapest way to hear radio amateurs, aircraft, ships and satellites. Receive only. |
| PMR446 walkie-talkies (Motorola Talkabout, Midland…) | Family, days out | No | ~€30-80 a pair | Legal with no paperwork and very easy to use. Short range. |
| CB-27 radio (President, Midland Alan…) | Citizens Band | No | ~€70-150 | Talk further than with a PMR without a licence, with an outdoor antenna or in the car. |
| Baofeng UV-5R | 2 m and 70 cm | Yes | ~€20-30 | Cheap, with loads of accessories and tutorials. Weak receiver and spurious emissions. |
| Quansheng UV-K5 | 2 m and 70 cm, listening to aviation | Yes | ~€25-40 | USB-C charging, receives the airband and supports open-source firmware. Filtering could be better. |
| TIDRADIO TD-H3 | 2 m and 70 cm | Yes | ~€40-55 | The best receiver of the cheap ones, a big battery, and you can program it from your phone. |
| Yaesu FT-65E (or equivalents from Icom and Kenwood) | 2 m and 70 cm | Yes | ~€100-130 | A benchmark brand, tough and splash-resistant. More expensive, with fewer features. |

From handheld to home station
The antenna matters more than the radio: a modest rig with a good antenna gets further than an expensive one with a poor antenna. Here is what you need and how to work out your first antenna.
Approximate lengths: cut them a little long and trim with the SWR meter. Cable losses are a guide and vary by manufacturer.
From the screen to the radio
The quickest way to learn is with other people: at a radio club they’ll teach you how to put up an antenna, prepare for the exam with you and, at their outreach events, you can try transmitting under supervision even if you don’t have a licence yet. .
Choose your province or tap a number on the map. There are also many independent radio clubs: ask at your nearest section.
Dates are worked out using each event’s usual rules. Confirm them on each organiser’s website before planning anything.
For families, the curious and young people
Five quick questions and we’ll tell you where to start.
Approximate prices; those for used equipment and a complete station come from the URE’s beginner’s leaflet. On top of this come the exam and authorisation fees.
Yes, and the regulations set no minimum age. For their station licence, the child provides a written authorisation from their parents or guardians, who take on the responsibility (Article 19).
Everything said on the radio is public: anyone can listen. That’s why you give your town, never your address, and don’t talk about personal matters.
Putting up outdoor antennas or handling power supplies should be done with an adult or at the radio club. It’s part of the exam.
Yes: the YOTA programme runs camps and the December YOTA Month for under-26s, and there’s the Jamboree on the Air with the Scouts.
For teachers and group leaders
A 50-minute session for young people aged 10 to 16, using this site and a printable worksheet. No radio knowledge or equipment needed: a projector or a few phones is enough.
To go further: invite a nearby radio club (see “Find your radio club”). Many give demonstrations in schools, and some help schools contact the ISS.
One A4 sheet with the phonetic alphabet, the Morse table, a fill-in contact script and a log to note down what they hear.
Only the worksheet is printed, in black and white. CC BY-SA 4.0 licence: you can copy and adapt it.

The exam and the simulator on this site follow the Spanish syllabus. Electricity, radio and operating are the same everywhere; regulations differ from country to country. To transmit from another country, first check licence reciprocity with its regulator. The regulators’ websites are in Spanish.
When everything goes down
With no mobile signal, no power and no internet, a radio with a battery and a length of wire keeps working. In Spain, volunteers from REMER (Red Radio de Emergencia, Civil Protection’s emergency radio network) and from radio clubs support communications during disasters. Many people come to amateur radio this way: wanting to be useful.
