Note 1. Intermodulation Suppression
measured with: 91% pilot signal; fm = 10 kHz or 13 kHz.
Note 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%)
Note 3. SCA ( Subsidiary Communications Authorization )
measured with: 81% mono signal; 9% pilot signal; fm=1kHz; 10%SCA - subcarrier ( fs = 67kHz, unmodulated ).
