Atlas 210x - Model 10 X Crystal Oscillator Schematic Diagram

CALCULATION OF CRYSTAL FREQUENCY:
For operation on lower sideband (LSB):
Bands 160, 75, 40 meters,
(Sideband Selector in NORM. position.) Crystal Frequency equals Signal
Frequency plus 5520 kHz. Example: 4020 + 5520 = 9540
Bands 20 and 15 meters,
(Sideband Selector in OPP. position.) Crystal Frequency equals Signal Frequency
minus 5523.3 kHz Example: 14,370 - 5523.3 = 8846.7 kHz
For operation on upper sideband (USB):
Bands 160, 75, 40 meters,
(Sideband Selector in OPP. position.) Crystal Frequency equals Signal Frequency
plus 5523.3 kHz Example: 4020 + 5523.3 = 9543.3
Bands 20 and 15 meters,
(Sideband Selector in NORM. position.) Crystal Frequency equals Signal
Frequency minus 5520 kHz Example: 14,370 - 5520 = 8850 kHz
