Filter BW:

Selects Composite filter bandwidth: RDS (passes stereo plus 57 kHz RDS), 67 KHz (passes stereo thru 67 kHz SCA, and

92 kHz (passes stereo thru 92 kHz SCA), and wideband. To reduce the interference from off-air-noise or HD carriers it is recommended that the
Composite filter bandwidth be set as low as possible depending on the SCA’s present.

Peak Mod:

Adjusts the threshold for the Total peak light on the Main Tuning Screen. When the threshold is exceeded, the red peak flasher will signal the

condition.

SCA

OPUP

ENU

The

FMCS-1

contains two independent SCA decoders SCA#1 and SCA#2. The parameters and setup of these decoders are the same so only one will be

described.

BPF Bypass:

SCA BPF bypass. When OFF the selected BPF filter is applied to the SCA before demodulation, ON removes the BPF which results in

approximately a ±20 KHz bandwidth around the center frequency.

BPF Freq:

Adjusts the center frequency of the SCA BPF filter, adjustable from 41.0 to 92.0 kHz in 0.1 kHz steps.

BPF BW:

Selects the SCA BPF bandwidth around the center frequency. The range is 1.0 to 16 kHz in 1 kHz steps.

DET Mod:

Specifies the type of detector used to demodulate the SCA. Choices are FM or None.

DET Resp:

The Detector Response maybe be set to Flat, 75 µsec, or 150 µsec.

DET BW:

Selects the Detectors LPF bandwidth, choices are 1.0 to 8.0 kHz in 1.0 kHz steps.

DET Norm:

Adjusts the normalization used to scale the modulation readings. The range is 1.0 to 7.0 kHz in 0.1 kHz steps. The normalization is typically

set to the maximum deviation of the SCA carrier; this normalizes the SCA peak reading for 100% @ max SCA deviation.

SET Peak:

Sets the SCA Peak Indicator limit. When this value is exceeded, the SCA peak indicator on the Man Tuning Screen will turn red. Range is

0.0 to 150.0% in 1.0% steps.

SET Mute:

Selects how the Mute function is applied to the SCA readings and Audio output. The Mute may be turned OFF (no muting), ON (always

muted), or AUTO (based on the SET Thres).

SET Thres:

Adjusts the threshold for the Mute and SCA Presence Indicator on the Main Tuning Screen. Range is 0.0 to 25.0% of SCA injection in 0.1%

steps.
