The PNI Escort HP-6550 Mobile CB transmitter with ECHO1 is a commercial-grade, multi-norm vehicular communication station precision-engineered to provide exceptionally clear voice synchronization, flexible multi-country spectrum tracking, and robust deployment readiness across active transport networks. Built specifically to fit into highly restricted vehicular cabins where dashboard real estate is limited, this ultra-compact radio measures just 110 x 120 x 28 mm, allowing fleet operators to mount the transmitter in the smallest of spaces. It stands as an essential operational procurement asset for long-haul shipping fleets, delivery transport networks, cross-border logistics units, and high-volume B2B radiocommunication accessory wholesale distributors looking to source turnkey multi-band CB installations.
The advanced internal RF core of the Escort HP-6550 operates on a standard 12-volt vehicle power loop over 40 channels spanning a frequency range of 26.965 – 27.405 MHz. Built to comply with various European trade borders, the system features comprehensive EU and United Kingdom multi-norm software settings, enabling instant toggle access across primary European frequency bands (EU, CE, UK, PL, I, I2, dE, In) under legal 4W emission power limits. To protect lines from continuous ambient atmospheric noise, the system introduces a double muting framework featuring a 28-level manual squelch (SQ) and a 9-level configurable automatic digital squelch (ASQ), alongside an agile 9-level configurable RF Gain function to precisely manage front-end radio reception gain under varying conditions.
This premium hardware configuration comes enhanced with the factory-integrated PNI Echo One (ECH01) module pre-installed directly inside the high-quality electret condenser microphone housing. This additional module unleashes advanced audio customization layout capabilities: the built-in Echo effect dynamically samples audio paths to inject a professional echo effect into the modulation stage, while the Roger beep engine transmits a custom end-of-transmission notification signal. By utilizing its built-in micro USB connector, operators can attach the microphone directly to a computer to rewrite the default roger beep signature with any personalized MP3 audio file, making it highly customizable for company branding or group synchronization tracking.
Featuring a net weight of 385g and designed to operate continuously across severe environmental climates from -26°C up to +80°C, this system is exceptionally easy to install thanks to its pre-wired car cigarette lighter power supply socket and simple RJ11 microphone connector. Delivering an immediate out-of-the-box solution, the box content includes the HP-6550 transmitter body, the custom echo/roger beep microphone, an adjustable transmitter mounting bracket with screws, a dedicated microphone clip with screws, a 12V power cord, and a detailed user manual.
