Garmin GTR 225/225A/225B Pilot’s Guide

The GTR 225 Com Radio series provides a powerful VHF communications 

transceiver in a small footprint at a very affordable price. Besides traditional Com 
features, the GTR 225 series also incorporates workload-reducing functions 
such as most-used frequency storage in memory. 

The GTR 225 series has the ability to monitor the standby Com frequencies. 

The GTR 225 (10 watt) Com radio operates in the aviation voice band, from 
118.000 to 136.975 MHz, in 25 kHz steps (default). For European operations, 
the additional Com radio configuration of 8.33 kHz steps is provided with the 
GTR 225A (10 watt) and GTR 225B (16 watt).
