1.1Product Description

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).
