What is Parrot Radio?

Parrot radio refers to radio communication systems designed and produced by Parrot Automotive (https://en.wikipedia.org/wiki/Parrot_Automotive). Parrot is a French wireless devices manufacturer that originally specialized in hands-free systems for vehicles. The company was founded in 1994 and entered the car radio market in the 2000s with Bluetooth car kits and aftermarket stereos.

Parrot radios are designed specifically for automotive applications, optimized for in-car entertainment, communication, and navigation. Key features of Parrot radios include Bluetooth connectivity, hands-free calling, audio streaming, satellite radio compatibility, GPS navigation, and touchscreen interfaces. Parrot introduced some of the earliest Android Auto and Apple CarPlay integration in aftermarket car stereos.

Some of Parrot’s most popular car radio models over the years include the Asteroid Smart, Asteroid Smart Nav, and Asteroid Nav. More recently, Parrot launched the RNB6 entertainment system aimed at the mainstream aftermarket car stereo market. Parrot radios distinguish themselves by their focus on high-tech connectivity and multimedia features tailored for the in-vehicle environment.

How Parrot Radio Works

Parrot radio utilizes short-range wireless transmission technology to enable hands-free calling and audio streaming in vehicles. At the core of parrot radio systems is a central controller unit that connects to a vehicle’s speakers and integrates with mobile devices via Bluetooth or USB. For example, the Parrot Asteroid Smart controller has a touchscreen interface and runs apps powered by the Android operating system (Parrot Asteroid review).

To enable hands-free calling, parrot radios use built-in microphones to pick up voice commands and conversations. Advanced noise cancellation allows clear communication even with road noise. The controller’s software automatically mutes music playback during calls. For music streaming, some parrot radio systems support apps like Spotify as well as playback from storage devices. The audio is optimized for in-vehicle acoustics.

Under the hood, parrot radios leverage system-on-a-chip architectures to integrate the controller, Bluetooth/WiFi connectivity, audio decoding, graphics processing, and other functions into a compact unit. For example, the Parrot Asteroid Smart is powered by a 1GHz ARM Cortex A8 processor (Parrot ASTEROID Smart In-Car Demo!). Parrot radios run embedded software optimized for in-vehicle use.

Parrot Radio Frequencies

Parrot radio operates primarily on the very high frequency (VHF) and ultra high frequency (UHF) bands. Some of the most common frequencies used for parrot radio include:[1]

• 146.52 MHz – This is the primary frequency monitored on the 2-meter band
• 52.525 MHz – Used on the 6-meter band
• 223.5 MHz – Operates in the 1.25-meter band
• 446.0 MHz – A 70-centimeter UHF frequency
• 1294.5 MHz – Used on the 23-centimeter band

The advantage of using these VHF and UHF frequencies for parrot radio is that they allow effective communication over moderately long distances, beyond line of sight. The frequencies can travel farther than normal FM radio due to diffraction effects.[1]

Most parrot radio repeaters and base stations transmit and receive on different frequencies, with an offset, to avoid interference. The transmitting frequency is usually 600 kHz above the receive frequency.[2]

Parrot Radio Equipment

Parrot radio uses specialized radio equipment that is distinct from other forms of radio communication. At its core, a parrot radio system requires both a transmitter and receiver configured specifically for parrot radio frequencies and protocols.

The parrot radio transmitter takes an audio signal as input, encodes and modulates it into a radio frequency signal, and broadcasts it through an antenna. Transmitters may be designed for different power outputs depending on the intended transmission distance. Handheld parrot radios typically transmit at under 5 Watts, while more powerful base station units can transmit at hundreds of Watts. The transmitter circuitry consists of audio processing components, a frequency generation module, a modulation module, a power amplifier, and the broadcasting antenna.

The parrot radio receiver is designed to detect the radio signals broadcast by the transmitter. The receiver antenna picks up the radio waves, which are then demodulated and decoded to recover the original audio signal. The receiver consists of an antenna tuned to the parrot radio frequencies, a high frequency amplifier, a demodulation circuit, and audio output components. Advanced receivers utilize digital signal processing for filtering and noise reduction. The recovered audio can then be played through a speaker or headset.

In order to communicate effectively, parrot radio transmitters and receivers must be tuned to the same frequencies and use compatible modulation methods. This allows multiple distinct radio conversations to occur simultaneously without interference. The configuration of the transmitter and receiver equipment determines the capabilities of the parrot radio system.

Constructing a Parrot Radio

Constructing a basic parrot radio system is relatively straightforward. At its core, a parrot radio consists of a radio transceiver, antenna, and audio cable to connect the transceiver’s speaker output to its microphone input. This creates a continuous loop that retransmits any signals received by the radio.

To build a parrot radio you will need:

• A two-way radio transceiver capable of operating in duplex mode
• An appropriate antenna for the frequencies used
• A cable to connect the transceiver’s speaker to its mic input
• Optionally, an external power source like a battery or AC adapter

The general construction steps are:

1. Connect the radio’s speaker audio output to its microphone audio input using an audio patching cable.
2. Tune the radio to the desired transmit and receive frequencies.
3. Enable duplex mode on the radio so it can receive and transmit simultaneously.
4. Attach the antenna and power up the radio.
5. Position the parrot radio system in the coverage area you want it to retransmit signals within.
6. Any received signals will now be “parroted” back out on the transmit frequency.

While simple parrot radios operate continuously, more advanced configurations can include features like tone controlled squelch to limit unwanted signals. Overall, constructing a parrot radio provides an easy introduction to building basic RF repeater systems.

Parrot Radio Applications

Parrot radios have several useful applications in various fields. For example, they can be used for two-way communication in remote areas where other radio systems may not work well. Some key applications of parrot radios include:

Emergency Services – Parrot radios are used by search and rescue teams to coordinate efforts over long distances and difficult terrain where regular radios have limited range. The radios provide clear communication even in remote areas which helps improve response times.(1)

Scientific Research – Scientists working in remote field locations use parrot radios for communication and data transmission. The long range capabilities allow teams to stay in contact even when spread out over large research sites.(2)

Military Operations – Parrot radios are valued for tactical communication in the military. Their resistance to jamming and interception provides secure battlefield communication critical for mission success.(3)

Aviation – Pilots of private aircraft rely on parrot radios for air-to-ground and ground-to-air communication when flying in areas outside air traffic control coverage. The radios provide clear communication in all conditions.

Maritime Operations – Boats working far offshore depend on parrot radios for ship-to-shore and ship-to-ship communication. The reliable long-range transmission keeps sailors connected and improves safety.

Parrot Radio Compared to Other Radios

Parrot radio stands in contrast to more traditional radio technologies in several key ways:

Broadcast Range

Whereas AM/FM radio relies on broadcast towers to transmit signals across long distances, parrot radio is designed for highly local and specific transmissions over shorter distances.

Infrastructure

Parrot radio does not require large broadcast towers or stations. It utilizes simple, low powered transmitters and receivers, making it easy to set up decentralized networks.

Connectivity

Unlike WiFi or cellular networks, parrot radio does not rely on internet connectivity. It creates isolated radio networks that can operate independently.

Applications

While AM/FM radio is used primarily for broadcasting, parrot radio has niche applications like connecting remote sensors, automation, or communication in isolated areas.

Regulations

Parrot radio operates on unlicensed frequencies and has fewer regulatory barriers compared to large-scale commercial radio broadcasters.

Parrot Radio Regulations

Parrot radio equipment and usage is subject to regulations in most countries. According to the Independent Communications Authority of South Africa, parrot radios must comply with applicable radio regulations and rules including section 95 (2) of the Electronic Communication Act.

In the United States, parrot radios must comply with Part 15 of the FCC rules for unlicensed transmissions. This includes limits on transmission power and prohibitions on causing harmful interference to licensed radio services. According to Parrot’s user guide, “This device complies with part 15 of the FC C rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.”

Users of parrot radios must comply with laws regarding usage while operating vehicles. Parrot’s user guide states “All functions requiring an increased attention should only be used while the vehicle is stationary. Your safety and the one of the other road users prevails over any other consideration.”
