Features Overview
Frequency Indication
A liquid crystal display (LCD) provides the frequency indication. The required operating frequency
is set by means of the rotary knob. The relation between the real operating frequency and the
displayed frequency is according to standard (ICAO Annex 10, Volume II). For an overview, refer to
the table below.

Audio Outputs
The GT6201 VHF Transceiver includes four fully configurable outputs:
•
Headphone 1 output, rated output power is 300 mW into 75 Ohm, (
with floating transformer
output)
•
Headphone 2 output, rated output power is 200 mW into 75 Ohm, (
differential output DC
coupled)
•
Speaker output, rated output power is 4 W into 4 Ohm,
(asymmetric AC-coupled output)
•
LINE-OUT output intended for ground station use only.
(asymmetric AC-coupled output)
Note: Headphone 2 and
speaker output cannot be active at
the same time
Mike Inputs
GT6201 has an input for dynamic microphone (DYN_MIKE) and an input for standard microphone
(STD_MIKE).
The GT6201 VHF Transceiver provides four microphone inputs:
•
Standard microphone input 1 (STD_MIKE1),
•
Standard microphone input 2 (STD_MIKE2),
•
Standard microphone input 3 (STD_MIKE3),
•
Dynamic microphone input (DYN_MIKE).
Each input is able to operate with one single microphone or with two microphones of the same type
connected in parallel.
