ATR833A VHF Transceiver

The Funkwerk ATR833A is a VHF radio in 160 mm format 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 headsets are separately adjustable. Using similar 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. In addition, the 10 last used frequencies can be recalled easily.

The OLED-display gives perfect readability under all lighting conditions.
