Module # 200 Crystal Filter - MAX-SSB Transceiver Project

Construction is complete on the MAX-SSB's Module # 200 Crystal Filter.

In this video I show the crystal filter or a.k.a. SSB filter. The job of the crystal filter is to remove one of the sidebands (either the upper or lower sideband) from an SSB signal (the carrier is usually removed by the balanced modulator). To test I used an A/B switch to compare the performance between my new filter and the existing filter in by earlier ZX-SSB-II rig. This was a quick go/no-go test but for the serious experimenter the use of a VNA or Spectrum Analyzer with tracking generator will show the true performance.

Keep homebrewing.
