Retevis RT84.
Digital ham radio, complying with digital protocol ETSI TS 102 361-1,-2. Clear sound and more powerful. Can talk to all intercoms with the same protocol.
Digital and analog compatible, Support digital and analog two communication modes to ensure that the original analog products smooth transition to digital products to meet different communication needs.
Large color screen to display almost all the information you want to check;
FPP: You can input the frequency directly;
The alarm function which is helpful for travel or in emerge conditions;
The most important is it can easily get into the repeater, and the firmware and software update for free.
