Product Description


An Explosion Proof Digital Walkie Talkie with APRS functionality is a specialized communication device that integrates traditional voice communication features with the capability to transmit and receive digital data using the APRS (Automatic Packet Reporting System) protocol. Here's a breakdown of the components mentioned:

Explosion Proof Digital Walkie Talkie:
An Explosion Proof Digital Walkie Talkie is a portable communication device designed to enable communication between two or more users over short distances. It operates on specific radio frequencies and typically includes features such as push-to-talk (PTT) functionality, channel selection, and sometimes encryption for secure communication.

APRS (Automatic Packet Reporting System):
APRS is a digital communication protocol widely used by amateur radio operators to transmit real-time information such as location, weather data, and messages over radio frequencies. APRS data packets are sent in a format that can be received by other APRS-equipped stations, and the information can be displayed on maps or shared through the APRS network.

Key Features of Explosion Proof Digital Walkie Talkie:

Voice Communication: Like a standard walkie-talkie, this device allows users to communicate with each other using voice transmissions.
APRS Data: In addition to voice communication, this device has the capability to send and receive APRS data packets. This data can include GPS coordinates, messages, weather information, and more.
GPS Receiver: To transmit accurate location data, the walkie-talkie likely includes a built-in GPS receiver that provides real-time positioning information.
Display and User Interface: The device may have a screen that displays received APRS data and potentially allows users to send APRS messages or set up certain parameters.
Output Power: The "5W" mentioned could refer to the output power of the device. In radio communication, higher output power typically allows for longer communication ranges, but regulations and antenna quality also play a role.
Amateur Radio Use: APRS is commonly used by amateur radio operators, so a walkie-talkie with APRS is likely intended for use within the amateur radio community.
