Retevis RT84 Digital Dual Band Ham Radio
The Retevis RT84 is a powerful digital dual-band handheld ham radio designed for reliable, clear communication in both amateur and professional environments. Fully compliant with the digital protocol ETSI TS 102 361-1, -2, -3, it delivers enhanced audio clarity, stronger signal performance, and broad interoperability with other radios using the same protocol.
Digital and Analog Dual-Mode Operation
Supporting both digital and analog communication modes, the RT84 allows for a smooth transition from legacy analog systems to modern digital networks. This flexibility ensures compatibility with existing equipment while unlocking the benefits of digital communication.
Clear Display and Intuitive Operation
A large, full-colour screen displays essential information at a glance, including frequency, channel details, and operational status. The RT84 also supports FPP (Front Panel Programming), allowing frequencies to be entered directly from the keypad without the need for a computer.
Built-In Safety and Security Features
An integrated alarm function provides additional safety during travel or emergency situations. Digital encryption support enhances communication security, helping to protect sensitive transmissions from interference or eavesdropping.
Repeater Friendly with Free Updates
The RT84 is designed for easy repeater access and supports free firmware and software updates, ensuring long-term usability and performance improvements without additional cost.
