We've been having great success with Retevis radios for marine and business radio in UHF and VHF and these dual-banders, aimed more at ham radio operators are quite impressive. Decent quality, drop-in charger and all the usual functions - and VERY modest price! Price includes delivery.
The spec is here:
- Ham radio easy to use; RT85 scanner radio; LCD large screen; keypad operation to edit functions; ideal for radio amateurs and beginners of two way radio
- Walkie talkie dual band; dual display; 200 channels; 50 CTCSS and 105 DCS; appropriate frequency and channel can be selected according to the environment
- Long range 2 way radio; High gain antenna; longer receiving range; 1750Hz; high power; longer communication distance
- Security and professional walkie talkie; with emergency alarm and LED flashlight; the emergency alarm function allows you to get help in time, and the LED flashlight avoids danger when the light is insufficient.
- Rechargeable walkie talkie for adults long standby; 1400mAh battery capacity and power saving function to meet the needs of daily work
- Professional walkie talkie with stable and hard plastic frame design; strong durability; effectively protects the machine performance and safety
- DTMF decode; remote stun; kill; activation; managers can restrict group members to transmit or receive; it is convenient to deploy tasks or unified commands
