CONTROLS AND SWITCHES

The FRG-7 has been designed for ease of operation. All controls have been properly adjusted at the factory. Several panel controls and switches are unusual in operation, and an improper setting may result in poor reception. The function of various controls and switches is described in the following paragraph. Be certain that you thoroughly understand the individual function of each before operating the receiver.

FRONT PANEL

(1) BAND
The BAND switch is a four position switch. The switch selects the desired frequency range.

(2) ATI (NOR. DX, LOCAL)
The ATT (attenuator) switch attenuates the incom-ing signal to prevent over-loading of the front end when an extremely strong signal is present. At the switch NOR (normal) position, the attenuator is removed from the input circuit.

(3) TONE (NOR, NARROW, LOW)
The TONE switch changes audio response of the receiver. The audio amplifier passes at the NOR position, 250 Hz through 3000 Hz, at NARROW 400 Hz through 2500 Hz band at LOW 250 Hz through 1500Hz.

(4) (5) TUNING DIAL
The main TUNING knob determines the frequency

in combination with the BAND switch and MHz setting.

(6) FINE TUNING
The FINE TUNING control is used for precise tuning of the received signal. The main tuning dial is calibrated to the frequency with the fine control at centre.

(7) VOLUME
The VOLUME controls the audio output level from the speaker.

(8) MODE
The MODE switch determines the appropriate detector in use. In the USBCW position. the USB (Upper Side Band) and code signal is heard. In the LSB position, the LSB (Lower Side Band) signal is heard. In the AM position, the ampLitude modulat-ed signal is heard and the Noise Limiter is put into the circuit in the AM/ANL position.
