Tools Used

• Modulation Bandwidth
  Primary

  Verify occupied bandwidth fits band segment for chosen mode.

• Signal-to-Noise Ratio
  Primary

  Estimate minimum SNR for reliable digital decode.

• Filter Cutoff Frequency
  Supporting

  Set IF and audio filters to pass mode bandwidth.

• Decibel (dB) Converter
  Supporting

  Convert reported dB values to power ratios for comparison.

• Frequency to Wavelength
  Reference

  Confirm operating frequency within digital subbands.

Reference Materials

• Clock Sync Is Critical

  FT8/JS8 fail with >1 s clock error — enable automatic NTP.

• Start on 20 m FT8

  Busy but forgiving — good place to learn waterfall operation.

• Watch for Overdrive

  Distorted TX audio reduces decode for others and invites reports.
