# Why Radio Matters in Emergencies
In the first hours of a serious crisis – power outage, flooding, a major storm – the mobile phone network is typically the first thing to collapse. Millions of people try to call simultaneously. Cell towers are overloaded or run out of backup power. Your smartphone becomes an expensive paperweight.
Radio devices are independent of mobile infrastructure, internet connections, and the power grid. They work battery to battery, directly between devices, without routing through any server. That makes radio one of the most resilient communication methods in emergencies.
But there is a catch: you cannot just buy a device and start broadcasting. Germany has clear rules about who may transmit on which frequencies – and enforcement is real.
# Why You Can’t Just Transmit
Radio is not a free-for-all. The entire frequency spectrum in Germany is managed by the Bundesnetzagentur (Federal Network Agency). Every frequency band is assigned to a specific use – aviation, emergency services, military, broadcasting, amateur radio, and the license-free PMR446 band.
This means: in Germany, transmitting on amateur radio frequencies requires the relevant amateur radio qualification, official authorisation, and a personal call sign. Transmitting on a frequency you are not authorized to use is an administrative offence under § 148 TKG (Telecommunications Act). The Bundesnetzagentur can confiscate equipment, and operators can be held liable for interference damage.
More importantly for emergency preparedness: unauthorized transmission on rescue frequencies or public safety channels disrupts critical communication during actual emergencies. That is not just illegal – it is dangerous.
The good news: there are two perfectly legal paths to being radio-ready.
# PMR446 – The License-Free Option
PMR446 (Private Mobile Radio) is the EU-wide system for license-free short-range radio. Within the EU, anyone can transmit on all 16 PMR446 channels without a license or registration – as long as the device is EU-approved and does not exceed 0.5 watts.
That sounds limited, but it is enough for many emergency scenarios: communication within a household, between neighbors, across a campsite, or within a hiking group.
What PMR446 does well:
- Instant communication with no prior knowledge required
- No registration, no license, no hassle
- Affordable devices (from around €30 per pair)
- Usable on the same channels throughout Europe
What PMR446 cannot do:
- Cover large distances (realistically 0.5–2 km in urban areas)
- Adjust channels or power output
- Access repeater infrastructure
Important when buying: Only purchase CE-certified PMR446 devices. Cheap imports without CE markings are often technically capable of exceeding 0.5 watts – making them illegal in Germany. Look for the PMR446 label and CE symbol on the device.
# Choosing the Right Walkie Talkie
For emergency preparedness, a few criteria genuinely matter – and many cheap devices fail to meet them:
AA batteries instead of proprietary packs. During a power outage, a device that only works with a built-in rechargeable pack is useless once the battery runs flat. Devices that accept standard AA batteries can always be resupplied – AA batteries are available in every supermarket, and they power half the flashlights you already own.
Built-in FM radio. A built-in FM tuner receives broadcasts from public stations, which continue to operate in emergencies. This is an underrated information source when the internet is down.
IP rating. Dust and water are real hazards in genuine emergencies. At minimum IPX4 (splash-resistant) – IP67 (submersible) is better.
Channel scan and emergency alert tone. Professional PMR radios automatically scan all channels for activity and have a dedicated alert tone that triggers all paired devices simultaneously.
Midland G9 Pro
★ Our PickThe Midland G9 Pro meets all these criteria: AA batteries (included), FM radio, IPX4 splash-resistant, channel scan, emergency alert tone, and a robust housing. It is sold as a single unit – plan for two to actually communicate (~€160 for a pair).
# Ham Radio – The Serious Option
Those who take radio communication seriously will eventually come to amateur radio. With a license, you may transmit on far more frequencies, at significantly higher power, and via repeater stations – installations that receive your signal and retransmit it with greater range.
In practice: while PMR446 struggles to cover 2 km in a city, a licensed amateur radio operator can reach 30–50 km through urban repeaters. In disaster zones where mobile networks have failed, amateur radio clubs operate independent emergency communication networks.
What ham radio adds:
- VHF (2m) and UHF (70cm) with up to 5 watts (Class E) or 750 watts (Class A)
- Access to repeaters for extended range
- Worldwide HF communication with Class A
- Active integration into organized emergency radio networks (e.g. DARC Notfunk)
- Technical knowledge enabling improvisation when equipment fails
# Getting Your Ham Radio License
The exam is administered by the Bundesnetzagentur and is structured in two tiers:
Class E (Entry level): Permits transmission on VHF and UHF bands with up to 100 watts. More than sufficient for emergency preparedness. Exam fee: €80.
Class A (Full license): Adds HF bands (worldwide communication), up to 750 watts, and all amateur radio bands. Exam fee: €80 (taken separately from Class E).
# Where to Take the Exam
Registration is handled directly through the Bundesnetzagentur (bundesnetzagentur.de). Exam sessions are held nationwide at regional offices throughout the year. In addition to the exam fee, there is a one-time registration fee of approximately €70 for your personal callsign.
The DARC (Deutscher Amateur-Radio-Club) is the main resource for preparation. Most of the 900+ DARC local chapters offer:
- Free or low-cost preparation courses
- Study groups and mock exams
- Mentoring from experienced operators
Online preparation: The DARC provides free study materials and question banks on its website. Apps and platforms such as AFu-Trainer allow structured self-study.
# Time Required
With 1–2 hours of daily study, Class E is achievable in 4–8 weeks. The syllabus covers operating procedures, regulations, and technical fundamentals. It is not a physics degree, but it does require genuine effort.
# Validity
The license is valid indefinitely and nationwide. Your personal callsign is yours for life. Through the CEPT agreement, the license is valid in 42 countries across Europe.
# The Right Ham Radio Device
For beginners – and especially for emergency preparedness – a compact handheld transceiver (HT) is the most practical choice. It fits in a jacket pocket, runs on batteries, and covers the key VHF/UHF bands.
The device most beginner operators worldwide start with:
Baofeng UV-5R
The Baofeng UV-5R is not a premium device – but it is a remarkably capable one for the price. It receives FM radio, can be powered by a standard 6×AA battery pack (sold separately for around €5), and covers both relevant amateur radio bands (VHF 144 MHz / UHF 430 MHz). For licensed operators, it is a solid and affordable starting point.
Important: In Germany, the Baofeng UV-5R may only be legally owned and used to receive without a license. Transmitting – on any frequency – requires a valid amateur radio license. It is not PMR446-compliant and may not be used as a PMR radio.
Those looking for better build quality and German-language support will find more robust alternatives from Yaesu (FT-60R, FT-70DR) in the €120–200 range. Kenwood devices like the TH-D75A are technically excellent, but at €400–500 they are firmly in the advanced segment – overkill for emergency preparedness beginners.
# AA Batteries: Why It Matters
This point is consistently underestimated. Almost all handheld radios ship with proprietary lithium battery packs. In normal use, that is convenient. In an emergency – after three days without power – the pack is flat and your charger is useless.
AA batteries are the universal emergency power source. They are inside flashlights, clocks, and remote controls. Quality batteries from Energizer or Duracell last 10–15 years on the shelf. And in a worst-case scenario, they are still available in every supermarket that accepts cash.
For emergency preparedness: choose devices that either run natively on AA, or for which an AA battery pack is available. The Midland G9 Pro runs natively on AA. The Baofeng UV-5R gains this capability with the separately available 6×AA pack:

Can I buy a PMR446 radio and use it immediately?
Yes – PMR446 devices with EU certification can be used without a license on all 16 PMR channels. The device must be CE-certified and limited to the permitted 0.5 watts. Many cheap import devices without a CE mark are not compliant and should be avoided.
What happens if I transmit on amateur radio frequencies without a license?
It is an administrative offence under the German Telecommunications Act (TKG) and can result in fines of up to €500,000. The Federal Network Agency can also seize the equipment. Intentional interference with emergency services can lead to criminal charges.
How long does it take to prepare for the ham radio exam?
With 1–2 hours of daily study, most candidates are ready for the Class E exam within 4–8 weeks. Class A requires an additional 3–6 months. The DARC offers free learning materials and courses through its 900+ local chapters.
How much does the ham radio exam cost in Germany?
The exam fee at the Bundesnetzagentur is €80 for Class E and €80 for Class A, plus a one-time callsign registration fee of approximately €70. Preparation courses vary but are often free for DARC members.
Is my German ham radio license valid abroad?
In most European countries, yes. Through the CEPT agreement, your German callsign is valid in 42 countries. Outside Europe, rules vary and a visitor’s license may be required.
How far do PMR446 radios actually reach?
Manufacturers claim 5–30 km, but these are ideal-condition maximums. In forests, cities, or buildings, 0.5–3 km is realistic. For emergency communication within your immediate area, this is often sufficient.
What is the difference between PMR446 and ham radio?
PMR446 is license-free short-range radio with fixed channels and 0.5 watts maximum. Ham radio allows significantly more power, many frequency bands, repeater infrastructure, and worldwide connections – but requires a license.
# Conclusion
Radio is one of the few communication technologies that works without infrastructure. Anyone serious about preparedness should have both: a PMR446 device for immediate, license-free use, and – in the medium term – a ham radio license for serious range.
The effort for a Class E ham radio license is manageable. The investment – around €200 for fees and a starter device – is minimal compared to what you can communicate when it matters.
And always check the battery situation. When the power goes out, the built-in pack will follow shortly after.
