What is an amateur radio and why use one?
An amateur radio operator (or ham radio operator) is someone who uses communications equipment to talk to others, explore frequencies, provide emergency assistance, or simply enjoy the hobby of using the airwaves.
Traditionally, this required expensive antennas, transmitters, and specific licenses. But today, thanks to technology, You can access many of these features directly from your cell phone..
Modern applications allow:
- Send messages via digital radio (VoIP or SDR)
- Listen to open broadcasts
- Participate in community channels
- Communicate by voice or text without a direct internet connection
How do these apps work?
Current developments leverage technologies such as software-defined radio (SDR), mesh networks (direct link between devices), and optimized VoIP.
This means you can use:
- Wi-Fi or Bluetooth connections to communicate with your loved ones
- Open transmission frequencies for long distance talking
- Radio simulators with real channels and coding
- Access to community servers for radio amateurs around the world
Some apps also allow you to connect external hardware, such as microphones, USB antennas, or SDR converters, further extending your phone's range.
Is it legal to use amateur radio on a cell phone?
Yes, as long as you follow certain rules. Most apps are limited to open or public channels, such as emergency, community networks or private groups.
If you want to transmit on official bands (such as HF, VHF, or UHF), you may need a license in your country. But for most basic functions, such as listening or communicating in closed groups, you don't need any permission.
Additionally, many platforms include security filters and automatic configurations to prevent interference or misuse of the spectrum.
Who can benefit from this?
Although it may seem like a niche hobby, more and more people are joining the world of digital amateur radio. These apps are useful for:
- Travelers or backpackers, who wish to communicate in areas without coverage
- Tech enthusiasts, who enjoy experimenting with signals and hardware
- Survival and preparedness groups, where communication is vital

It's also an engaging way to learn about frequencies, waves, modulation, and telecom concepts related to high-eCPM niches like networking software, VPNs, automation, ERP, and IoT.
Security, privacy and control
When it comes to alternative communication, security is a crucial issue. Some apps include:
- End-to-end encryption for closed groups
- Access control using private keys or authorized channels
- Recording broadcasts for later review
- Integration with VPN or virtual private networks for greater anonymity
These measures are ideal for those who use these tools professionally, such as logistics personnel, community operators, or even educators teaching basic electronics.
