To get the job done, you work hard.

You need a walkie-talkie that can take it and keep up.

Motorola's RDX series two-way radios do all that and more. The RDX walkie-talkie runs on a metal die-cast chassis housed in a polycarbonate overmold. Made to military specifications 810 C, D, E, F and IP 54/55 for moisture, shock, vibration, dust and temperature extremes as high as 140F and lows of -22F -- how shall we put this delicately -- this walkie-talkie works under conditions that will kill you.

Not just hearty and high performance, Motorola RDX series two-way radios are dead easy to use too. Advanced Voice Activation (VOX) lets you use your radio without using your hands. Just talk in the direction of your mic and the VOX technology senses your intention to transmit and delivers your message (requires accessories, sold separately). Several models feature a programmable front panel with a back-lit display.

The RDX series offers radios that work on either the UHF or VHF band. You can tell which is which by the model number: RDU is UHF, RDV for VHF. Because the Motorola RDX series handheld radios broadcast and receive on frequencies set aside for the business community, 438-470MHz for UHF and 146-174 for VHF, an FCC business license is required to use them.
