New Arrival! RT84 Dual Band DMR Radio is on the market
Retevis RT84 is a Direct Mode/Dual Capacity Direct Mode (DCDM) radio, it is the dual band DMR radio.
The price is just $86.99, very Economical, high performance-price ratio, very suitable for entry level hams.
The menu is smooth to use, and feels very comfortable. You can operate some function by menu, such as side button, P1, P2, One touch Access and so on.
RT84 Main Futures:
- Broadband walkie talkie
Support UV double segment, frequency range: UHF 400.000 – 480.000Mhz; VHF: 136.000 – 174.000Mhz.
- DMO True 2-Slot dual time slot
Direct mode dual-slot communication achieves two groups of calls at a frequency point at the same time,
so that the communication efficiency is doubled and frequency resources are saved.
- Digital and analog compatible, smooth over
Support DMR digital and analog two communication modes to ensure that the original analog products smooth transition to digital products,
to meet different communication needs.
- Digital signaling function
Rich calling modes that support DMR protocol, including single call, group call and all call; S
upports remote inhibit function and other applications.
- SMS function
Supports SMS, text editing and draft in 64 characters in chinese and English,
so that text messages calls can be sent when voice call is inconvenient.
- High sound quality
This digital two-way radio uses advanced AMBE+2TM voice processing technology to achieve high quality.
- Manual writing-frequency
Support channel/ frequency mode, allows manual writing-frequency in frequency mode,
and writing-frequency software can be used to set the required frequency without connecting the computer.
