deviation), modulation frequency = 1kHz, input gain = 6dB, T
otherwise specified.
Notes to the characteristics:
1. Intermodulation Suppression:
measured with: 91% pilot signal; fm = 10kHz or 13kHz.
2. Traffic Radio (V.F.) Suppression:
measured with: 91% stereo signal; 9% pilot signal; fm= 1 kHz; 5% subcarrier (f = 57kHz, fm = 23Hz AM, m = 60%)
3. SCA (Subsidiary Communications Authorization)
4. ACI ( Adjacent Channel Interference ):
measured with: 90% mono signal; 9% pilot signal; fm =1kHz; 1% spurious signal( fs = 110kHz or 186kHz, unmodulated).
