ELECTRICAL CHARACTERISTICS (continued)
Notes to the characteristics:
1. Intermodulation Suppression:
2. Traffic Radio (V.F.) Suppression: measured with: 91% stereo signal; 9% pilot signal; fm=1kHz; 5% subcarrier (f = 57kHz,
3. SCA ( Subsidiary Communications Authorization ) measured with: 81% mono signal; 9% pilot signal; fm = 1kHz; 10%SCA - subcarrier
4. ACI ( Adjacent Channel Interference ):
8/28
