5. Operating Instructions

5.1 Basic Operation

• Volume Control: Use the VOL+ and VOL- buttons to adjust the listening volume.
• Band Selection: Press the BAND+ or BAND- buttons to cycle through the pre-configured frequency bands (FM, LW, MW, SW).
• Tuning: Rotate the large TUNE/BFO/ATS knob to change the frequency within the selected band.
• Frequency Step: Press the STEP button to change the tuning step size (e.g., 1kHz, 5kHz, 10kHz) for finer or faster tuning.

5.2 Mode Selection (FM, AM, SSB)

Press the MODE button to switch between different reception modes:

• FM (Frequency Modulation): For local FM broadcast stations. The radio supports FM stereo.
• AM (Amplitude Modulation): Includes Medium Wave (MW) and Shortwave (SW) bands for long-distance and international broadcasts.
• SSB (Single Sideband): For amateur radio (ham radio) and utility stations. This mode includes LSB (Lower Sideband) and USB (Upper Sideband). When in SSB mode, use the TUNE/BFO/ATS knob for fine-tuning the BFO (Beat Frequency Oscillator) to clarify the audio.

5.3 Bandwidth (BW) Filter

Press the BW button to cycle through the available audio bandwidth filters. Selecting a narrower bandwidth can help reduce interference from adjacent signals, especially useful for SSB reception.

• Available filters: 0.5KHz, 1KHz, 1.2KHz, 2.2KHz, 3KHz, and 4KHz.

5.4 Automatic Gain Control (AGC)

The AGC button toggles the Automatic Gain Control feature. AGC helps maintain a consistent audio output level despite variations in signal strength, improving listening comfort.

5.5 Pre-configured Bands

The radio comes with 22 pre-configured commercial and ham radio bands. Use the BAND+ and BAND- buttons to navigate these bands. Below is a general overview of the supported frequency ranges:
