Description

Compact, rugged UHF PMR446 transceiver

The Icom IC-U20SR is a portable analog UHF PMR446 transceiver engineered for durability and reliable performance in professional environments. With its compact footprint (50 × 94 × 26.7 mm, antenna excluded) and low weight (just 157 g), it suits a wide range of applications.

Backlit LCD and intuitive operation

The large backlit LCD ensures clear visibility of characters and icons even in bright sunlight. The simplified keypad is designed for quick, straightforward use: minimal controls, maximum practicality. An ideal solution for high-turnover work settings where the radio is shared by multiple operators throughout the day.

VOX and channel announcement

The integrated VOX function enables hands-free communication without pressing the PTT key. The Channel Announcement feature simplifies channel selection and scanning, allowing you to identify the active channel without looking at the display.

Programmable keys and Smart Ring / Call Ring

The IC-U20SR provides two programmable keys: an orange top key, easy to locate (ideal for emergency calls), and a side key below the PTT dedicated to Smart Ring and Call Ring functions.

Smart Ring confirms whether the called party has received your call, while Call Ring serves as an incoming call alert.

Extended runtime and IP54 protection

Key highlights include up to 21 hours of battery life (5:5:90 duty cycle), IP54 protection against dust and splashes, and USB charging capability.
