ATR833 LCD VHF Transceiver

The ATR833 LCD radio is a complete voice communication solution for small aircraft in 2 ¼‘‘ standard housing with the new channel separation of 8.33 kHz. The channel spacing can be switched between 25 kHz and 8.33 kHz. The built-in voice controlled intercom operates up to 4 microphones (2 standard, 2 dynamic). In many cases, no extra intercom is required. This saves cost and weight. All microphones are separately adjustable. Using suitable headsets, a 4-place intercom can be built up.

In addition to the standard functions, there are 2 memory functions available: Up to 100 frequencies can be stored together with an identifier. Moreover, the 10 last used frequencies can be recalled easily. The LCD display is perfectly readable in sunlight and consumes significantly less power. These characteristics are especially interesting for glider pilots. The ATR833 LCD can be controlled remotely by using the ATR833RT remote
