Two-Way Radio Basics
Which is better UHF or VHF? UHF offers the best coverage and penetration inside buildings or outdoors. VHF is fine in flat open areas or around wood structures.
How much power do I need? Power is a major factor in achieving the range and coverage in a particular structure as well as providing a clear, crisp signal that is easy to understand. Coverage is improved when power is increased.
How many Channels do I need? One channel per work group is typical. Use multi-channels when separating multiple workgroups. Examples: Managers, shipping, manufacturing, maintenance, security, general and sub contractors, different departments such as stock, customer service, etc.
Do current Motorola radios talk to older models and other brands? Yes, as long as the frequencies and codes match.
How many two-way radios can be used together? There is not limit.
How rugged are Motorola two-way radios? These radios are built rugged for business and meet Motorola's accelerated life testing including a 5 foot drop to concrete on all sides.
Can they be used with repeaters and base stations? CLP, RDU 4 Watt, RDV 5 Watt and AX models are dealer programmable to work with repeaters and base stations. See page 8 for Range Extender/Repeater.
Inexpensive FRS/GMRS Walkie-Talkies
While recreational models are inexpensive, their cost to use is 2 - 4 times greater than business models over time. Units and batteries are replaced often. GMRS requires FCC license just as business models, but are not legal to businesses, violators subject to fines.

Range & Coverage
Most business users need to communicate “on-site” in and around their structures. Coverage of their facility with a clear, intelligible signal is the primary concern. Wide area coverage of several miles may require use of a “repeater”. HP Series radios are compatible with repeaters.
Range is determined by several factors:
- UHF provides the best coverage indoors and out, especially in steel and
concrete structures and large industrial or multi-story buildings. A 2 watt UHF
will provide better coverage inside industrial buildings than a 5 watt VHF.
- VHF is good for outdoor “line of sight” applications and inside wood structures
- Power More power provides greater coverage and penetration
- Obstructions Structures, metal, steel and concrete reduce range and coverage
- CLP Series radios are equipped with 90 UHF frequencies
- CLS Series radios are equipped with 56 UHF frequencies
- RDX radios are equipped with 89 UHF or 27 VHF frequencies, depending on the radio model
- RDX high power radios are programmable to match other models, other brands, base stations and repeaters
- XTN Series radios are equipped with 56 UHF or 27 VHF frequencies, depending on the radio model
- AX Series radios came with factory programmed frequencies and were also custom programmable

*Due to FCC regulations these frequencies (six in total) are different from the previous Motorola Legacy Series radios. This means that if you select the RDX radio in one of these frequencies the radio will not inter-operate with an XTN radio. In order for a RDX radio to inter-operate with an XTN radio, make sure you choose any of the frequencies (21 in total) that are common for both radios.
**Bandwidth for frequencies 10, 22 and 27 are not selectable and different from XTN. You might notice the communication quality differences when using these frequencies to inter operate with XTN radios |

Interference Eliminator Codes
Interference Eliminator Codes prevent hearing other nearby businesses's operating on the same channel. This promotes workgroup efficiency as your group is not interrupted hearing these other users. Business two-way radios are set to the same frequency and code setting that will communicate with each other. There are 121 codes available on XTN, CLS and AX Series two-way radios. Codes are easily changed by the user on the XTN and CLS Series.
