1.14.2Operation

Beat adjustment

When using an external receiver whose beat frequency is adjustable within a range of ±2 kHz or more by means of a beat knob, set the frequency dial so the deflection of the receiver’s S-meter is maximum, and adjust the beat knob so that the center LED of the tuning indicator of this unit is lit. When a signal from a station with ISB communication (U.S. Naval Station Guam, Pearl Harbor, San Francisco, etc.) is received, sometimes an adjustment of the frequency is necessary, with a variable condenser, because the frequency may shift from the nominal frequency of the station by ±2 kHz.

Bandwidth

Increase bandwidth when noise is few, and lower bandwidth by about 1 kHz when noise is great.

Recording

Set up for recording referring to paragraph 1.6 (automatic) or paragraph 1.7 (manual). For reverse reception, set the mode on the external receiver to BFO (Beat Frequency Oscillator), or switch between LSB (Lower Sideband) and USB (Upper Sideband).
