Notes about the characteristics
Intermodulation suppression
measured with: 91% pilot signal; fm = 10kHz or 13kHz.
Traffic radio (V.F.) suppression
measured with: 91% stereo signal; 9% pilot signal; fm=1kHz; 5% subcarrier
(f=57kHz, fm=23Hz AM, m=60%)
SCA (subsidiary communications authorization)
measured with: 81% mono signal; 9% pilot signal; fm=1kHz; 10%SCA - subcarrier
(f
S
=10kHz, f
=13kHz, f
= 67kHz, unmodulated).
