The AOR AR-Mini U can perform voice inversion decoding. This built-in, standard feature recovers intelligible audio from certain types of analogue voice transmissions which would otherwise sound scrambled. This feature operates by splitting up the audio spectrum and flipping the upper and lower tones around a certain frequency point. This enables 157 different flip points to be selected in the audio frequency range of 2.4 kHz to 5.6 kHz. The table below illustrates the relationship between value and flip frequency.

Frequency in kHz  2.4 2.8 3.2 3.6 4.0 4.4 4.8 5.2 5.6 6.0 6.15
Inverter value  0 37 64 86 102 116 128 138 146 154 156

NOTES: The AOR AR-Mini U is available for government users or for export only! This capability is not available in the AR-Mini B version.
