AOR Alpha

The AOR AR-Alpha professional communications receiver

The AOR AR-Alpha is a new professional grade communications receiver which may be 19-inch rack mounted or used as a desk-top receiver.

With continuous coverage from 10 kHz to 3.3 GHz (Cellular Blocked for US consumer version), using wide band receive, advanced DDS and DSP technology, the AR-Alpha delivers a powerful monitoring, searching and recording capability. Fast frequency processing is achieved by means of FFT and signals are visually displayed on the 6.4″ TFT LED display both spectrally or as a waterfall function. TV signals can also be displayed (NTSC, PAL).
