Overview
The Motorola Radius P110 is a compact, portable two-way radio engineered for dependable field communication across VHF and UHF frequency bands. Built on synthesized, field-programmable architecture, the P110 delivers clear transmission with flexible frequency assignment and channel configuration. Models range from 2-watt to 5-watt output across both VHF and UHF variants, making it suitable for short-range urban deployments or extended coverage in rural environments. The P110 has been a proven workhorse in professional communications since its introduction in the 1990s, though now primarily available as used or surplus inventory.
Key Features
- Synthesized Design: Field programmable with multiple-coded squelch capability and wide band frequency separation.
- Flexible Configuration: Available in 2-channel 2-watt models (VHF or UHF), 2-channel 4-5 watt models, and 8-channel configurations.
- 8-Channel Model Enhancements: 8-channel models add MDC encoding, Quik-Call II decoding, and priority channel scan.
- Rugged Design: Operating controls positioned on top of the unit for easier handling, with PTT button on side.
- Compact Form Factor: 18 oz weight and 6″ H × 2.4″ W × 1.85″ D dimensions; passes Mil Spec E/A RS-316B.
- Standard Accessories: Includes 1200 mAH rechargeable nickel-cadmium battery, 10-hour charger, 3″ spring-action belt clip, and antenna (heliflex VHF or whip UHF).

Typical Applications
The Motorola Radius P110 is commonly deployed in:
- Industrial maintenance and facility management teams.
- Public safety dispatch and emergency response (where authorized).
- Construction site coordination and logistics.
- Security and loss-prevention operations.
- Ham radio and amateur radio enthusiast use (where applicable).
- Commercial fleet and transportation communication.
Compatibility & Replacements
Compatible With
- Motorola Radio Service Software for programmable configuration via local Motorola Radius dealer.
- Aftermarket chargers (HTN9630, HTN9802, HTN9803, HTN9167, HTN9168 series).
- Standard VHF (146-174 MHz) and UHF (403-520 MHz) two-way radio infrastructure.
- CTCSS/PL and DCS/DPL tone systems.
Replaces / Drop-In Replacement For
Specific model variants include P44QLC20A2AA (UHF 25 kHz wideband 4W), P24 series (2W variants), P44QLC00A2AA (UHF 12.5 kHz narrowband), and P93 series for VHF. Verify the exact model number (typically found on a sticker under the battery) to confirm interchangeability. P110 radios were discontinued around 1996, so direct replacement options from Motorola are limited.
Works With
- Motorola aftermarket VHF and UHF antenna kits for various frequency bands.
- Standard nickel-cadmium battery chargers with appropriate voltage/frequency (120V, 220V, 240V models available).
- External audio accessories (headsets, speaker-microphones) via standard connector.
- Compatible with analog FM two-way radio repeater networks using CTCSS/DCS encoding.
