Traffic Radio (Note 2)

Signal

SCA - Subsidiary Communications Authorization (Note 3)

Signal

f = 67KHz

ACI - Adjacent Channel Interference (Note 4)

Signal

f = 114KHz

f = 190KHz

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=1kHz; 5% subcarrier (f = 57kHz,

fm = 23Hz AM, m = 60%)

3. SCA ( Subsidiary Communications Authorization ) measured with: 81% mono signal; 9% pilot signal; fm = 1kHz; 10%SCA - subcarrier

( fs = 67kHz, unmodulated ).

4. ACI ( Adjacent Channel Interference ) measured with: 90% mono signal; 9% pilot signal; fm =1kHz; 1% spurious signal

( fs = 110kHz or 186kHz, unmodulated).

5. By Design/Characterization but functionally guaranteed through dedicated test mode structure
