Communication between the SR 71 and the KC 135Q had to be secure. The enemy would listen in vain, trying to find their location and their next rendezvous with a tanker. The RSO had a Modulator/ demodulator modem control panel. He used a five-digit code that he punched to secure communications. The KC 135Q, which is equipped with the same UHF radio and has the correct mission code and address number, could receive the SR 71 range as well. There was an interconnected phone that the crewmembers of both the SR 71 and the KC 135Q could talk to each other during this refueling time.

The tankers were always a welcome sight to the SR 71 crew. After a while, the cockpit would get a little warm. After refueling, the cockpit was noticeably cooler. Tankers could give life-saving information to the crewmembers by being able to look at the airplane and noticing if something was Wrong (Engine on fire, yes, that happened) with the airplane. Thank you to all KC 135 pilots and crewmembers for helping keep the SR 71 going all those years.

Avery Dennison at The Battery Show 2025

Avery Dennison will return to The Battery Show Europe 2025 in Stuttgart to showcase its latest innovations in pressure-sensitive adhesives and RFID technologies — designed to meet the evolving needs of electric vehicle (EV) battery manufacturers and OEMs.

Under the theme 'Making Possible,' the company will present how its solutions connect the physical and digital to ensure safety, performance and longevity across the battery lifecycle. With a portfolio that spans bonding, insulating, protecting and tracking, Avery Dennison supports every layer of EV battery design — from cell to pack.

“We’re focused on delivering solutions that help our customers meet the industry’s toughest demands,” said Martin Dolezal, marketing manager, automotive and energy storage. “Whether it’s enhancing thermal management, achieving digital traceability or reducing material impact, our technologies are built to perform in real-world conditions and ready for what’s next.”

Performance tapes: Electrical insulation and tailored venting films

Attendees will find out more about two key tape technologies essential to modern EV battery architecture, including electrical insulation films that deliver robust dielectric protection for critical components like cell connections, busbars, module plates and cooling ribbons.

Do You Know How Do Blank RFID Cards Work?

Blank RFID cards work based on RFID technology, which communicates with RFID readers via radio waves. The complete system of RFID is composed of an RFID tag, an RFID Reader, and a backend system. The following is a detailed breakdown of how an RFID card works:

Energy Transmission Most RFID cards are Passive, which means that the card itself has no built-in power source. When the card enters the electromagnetic field range of the reader, the reader powers the card through electromagnetic waves. This process is known as energy coupling and is usually achieved in the following ways:

Inductive coupling (LF and HF RFID cards): The electromagnetic field generated by the reader creates an induced current with the antenna coil in the card, powering the card chip.

Backscattering (UHF RFID cards): UHF cards communicate by reflecting and modulating the electromagnetic waves emitted by the reader.

Data communication When a card is powered, its chip activates and communicates with the reader. Data is transmitted between the card and the reader by modulation of radio waves. The following two modulation methods are usually used:

Reader-to-card communication: The reader sends a continuous RF signal, which is “demodulated” by the card's internal circuitry to extract commands.

Card-to-reader communication: The card transmits data by modulating the reflected signal by changing the impedance of the antenna. This technique is called load modulation, and the reader receives and decodes the reflected signal.

Data processing Read data: When the reader sends a read command, the blank RFID card transmits the data back to the reader according to the preset information stored inside it (such as a unique serial number or ID number). In the case of a blank card, the data may be null or the initial value of the preset.

Write Data: For writeable RFID cards, the reader can be commanded to write new data to the card's memory. For example, a user can write identity information or access rights on a blank card.

Digital Radio Spy

Digital Radio Spy: The Ultimate Guide to Staying Tuned In

What is Digital Radio Spying?

Using specialized hardware and software to record and decode signals from digital radio transmissions is known as “digital radio espionage.” Digital radio uses complicated encoding systems that call for more advanced equipment, in contrast to traditional radio, where the signal is frequently analog and reasonably simple to decode with a basic receiver.

This hobby or practice is widely used by:

Amateur radio enthusiasts: who enjoy exploring and listening to different frequencies.

Security researchers: testing wireless systems for vulnerabilities.

Aviation fans: listening to air traffic control (ATC) communications.

News agencies: to monitor emergency services and breaking events.

The Evolution of Radio Technology

Before we dive into the tools of digital radio spying, let’s take a brief look at how radio technology has evolved:

AM/FM Radio: Amplitude modulation (AM) and frequency modulation (FM) were the main ways to transmit audio signals over the airways for many years. These technologies have long been a part of radios found in homes, cars, and portable electronics.

Digital Radio: Digital radio emerged as a result of technological advancements, providing improved sound quality, increased content availability, and data transmission capabilities (such as text, photos, and more).

SDR (Software-Defined Radio): This is the application of digital radio espionage. SDR offers greater flexibility and usefulness by using software to tune into frequencies and decode digital signals rather than relying on conventional hardware receivers.

How Does Digital Radio Spy Work?

SDR technology is the foundation of digital radio espionage. You attach a software platform to hardware intended for capturing radio signals in place of a physical radio receiver. After then, the software can be configured to detect a large spectrum of frequencies, interpret the signal, and display it in a format that is useful.

Here’s a basic breakdown of the setup:

SDR Hardware: You may record radio waves with this gadget, which you can link to your phone, tablet, or computer. RTL-SDR dongles, HackRF, or more sophisticated SDR receivers for experts are common choices.

SDR Software: You’ll need software to decode and interpret the signals. Some of the most popular programs for digital radio spying include:

SDR (SDRSharp): A highly popular software for Windows that supports RTL-SDR and other SDR hardware.

Gqrx: A widely-used SDR application for Linux and macOS.

CubicSDR: Cross-platform SDR software with a simple and intuitive interface.

Antennas: A single SDR device is insufficient. To pick up the precise frequencies you want, you’ll need the right kind of antenna. Different antennas can be needed depending on if you’re interested in UHF, VHF, or other bands.

Decoders: Decoders are required in order to decode digital signals, which can include encrypted data, digital voice, or digital television signals. Tools like DSD+ can aid in decoding digital voice, but other applications may be necessary for more specialized forms.

Popular Uses of Digital Radio Spying

Digital radio spying serves multiple purposes, depending on the type of signal being captured. Here are some of the most common uses:

1. Monitoring Air Traffic Control (ATC)

Digital radio eavesdropping is a tool used by aviation enthusiasts to listen in on pilot-to-air traffic controller interactions. Even while this is quite lawful in many regions of the world, it’s crucial to confirm your local laws.

2. Tracking Maritime Communications

SDR can be used to intercept and decode signals from ships and marine communications, including emergency broadcasts, in a manner similar to ATC monitoring.

3. Decoding Weather Satellites

One exciting application is decoding messages from weather satellites. You can directly obtain photos and meteorological information from satellites orbiting the Earth by intercepting these transmissions.

4. Amateur Radio Listening

A lot of digital radio spies also listen in on amateur radio broadcasters on different frequencies. Listening to global HAM radio enthusiasts is possible with SDR.

5. Emergency Services Monitoring

Emergency services continue to use analog or digital transmissions in some areas. In the event that these messages are not encrypted, digital radio spies could be able to hear them. However, it is prohibited in many jurisdictions to listen to encrypted emergency services.

Ethical Considerations

While there are many interesting potential for digital radio espionage, it’s crucial to keep in mind that there are important ethical and legal considerations. Understanding the laws governing radio interception in your nation is crucial. It may occasionally be unlawful to listen to specific frequencies, such as those utilized by the military, police enforcement, or encrypted services.

Ethical digital radio spying means respecting these boundaries:

Do not intercept encrypted signals unless authorized.

Avoid using the information gathered for illegal purposes.

Respect privacy laws and regulations, especially when dealing with personal or sensitive data.

The Legal Landscape of Digital Radio Spying

The legalities surrounding digital radio spying vary by country. Here are some general guidelines:

In the United States, Radio transmissions are governed by the FCC, and it is illegal to intercept some messages without authorization, particularly those that are encrypted. It is, however, usually acceptable to tune in to open, unencrypted broadcasts such as amateur radio or ATC.

In the United Kingdom, Ofcom oversees radio communications, and it is illegal to listen to any broadcast that you are not authorized to hear, including emergency services, private business communications, and encrypted transmissions.

In Australia, the Australian Communications and Media Authority (ACMA) regulates radio communications, and similar rules apply. However, amateur radio and weather satellites are typically open to interception.

Before starting any digital radio spying activities, always research the specific legalities in your country to ensure you’re complying with the law.

Getting Started with Digital Radio Spy

If you’re eager to dive into the world of digital radio spying, here’s a basic list of things you’ll need to get started:

An SDR Receiver: The most accessible and budget-friendly option is an RTL-SDR dongle. For more advanced users, devices like the HackRF or Airspy offer higher performance.

Software: Download SDR# or CubicSDR to get started. These programs allow you to tune into frequencies and decode signals.

Antennas: Depending on your focus, you may need different types of antennas for UHF, VHF, or HF bands.

Decoding Software: If you’re capturing digital signals, you’ll likely need additional software like DSD+ to decode digital voice or satellite data.

Patience and Experimentation: Digital radio spying involves a bit of trial and error. Start by exploring publicly available frequencies, and gradually work your way toward more complex signals.

Future Trends in Digital Radio Spy

The future of digital radio spying looks promising as technology continues to advance. We can expect:

Improved SDR hardware: With higher sensitivity and greater frequency range, future devices will allow for even more in-depth signal analysis.

More decoding tools: As digital radio formats evolve, so will the tools designed to decode them, making it easier for enthusiasts to capture and interpret signals.

Integration with AI: Artificial intelligence could play a role in analyzing and interpreting large volumes of intercepted data, automating some of the more complex aspects of digital radio spying.

Conclusion

Digital radio spying is both an engaging pastime and an effective tool for experts, researchers, and enthusiasts. You may access a world of secret signals using SDR technology, including air traffic control communications and weather satellite signals. But it’s crucial that you approach this activity knowing what the ethical and legal requirements are in your area.

What frequencies can HAM radios receive?

HAM radio, also known as an amateur radio transceiver, is a powerful and versatile device capable of receiving a wide range of frequencies. These frequencies range from longwave to UHF for broadcasting, communications and exploration.

One of the most famous features of HAM radios is their ability to receive shortwave (SW) frequency bands. Shortwave broadcasting covers a broad spectrum from 3 to 30 MHz, including international broadcasting, weather information, maritime communications, etc. With HAM Radio, you can experience music, news, religion and other entertainment programs from around the world.

HAM radios also have the ability to receive frequency modulation (FM) broadcasts. FM radio typically transmits in the 88 to 108 MHz range and covers content such as local radio stations, music programs, news and sports coverage. HAM radio enables amateurs to capture local radio stations in the surrounding area to enjoy a diverse range of music and infotainment.

AM radio is still available in many places, whether in urban or rural areas. HAM radios are capable of receiving amplitude modulation (AM) broadcasts, which typically transmit between 535 and 1605 kHz. You can listen to various radio programs such as news, talk shows, sports reports, etc.

The WB band (162.400 to 162.550 MHz) is specially established for weather information services and can receive real-time weather reports and warnings from the Meteorological Bureau. The AIR band (108 to 137 MHz) is an important frequency band for aviation communications. You can monitor the conversation between the aircraft and the tower and experience the excitement and fun of aviation.

Through the amateur band, HAM radio users can conduct point-to-point communications, long-distance communications, weather reports, emergency rescue and participate in amateur radio competitions to communicate and share information with other amateurs around the world.

HAM radio is a radio wonder with multi-band reception. It is not only capable of receiving conventional frequency bands such as broadcasting, communications and weather, but also allows amateurs to enter the colorful world of amateur frequency bands. Whether exploring international broadcasts, capturing local music shows or communicating with other hams, HAM Radio gives you a wide range of radio experiences and endless possibilities.

These days, some development boards come with an absolutely astounding variety of hardware. The EESP32, a tiny LoRa board with WiFi, Bluetooth, a transceiver that spans a large portion of the UHF band, and conveniences like OLED displays and an abundance of GPIO, are a perfect example. What about the documentation and firmware, though? Basically, do not say anything at all if you can not say something kind. Better yet, just take a roll. That is not true for every LoRa dev board available, of course, but [Rop] found that to be the case with the Heltec HTIT-WB32LA. This board needed some assistance to get over the line, but it has all the bells and whistles and would be ideal for LoraWAN and Meshtastic applications. Based on his fork of the RadioLib library, which includes a library that significantly lessens wear on the ESP32's flash memory, [Rop] has contributed a fair amount to this end. The library supports all of the hardware on the board, including the pushbutton, display, power management, battery charging, and blinkers, in addition to complete radio support. Many sample applications are included in [Jop], ranging from the minimal requirements to spin up the board to a fully functional spectrum analyzer. It is a wonderful piece of work and a wonderful way to support the LoRa community. And if you want to put one of these modules to work, you’re certainly in the right place. We’ve got everything from LoRaWAN networks to the magic of Meshtastic, so take your pick and get hacking.
