SSB6 Design
Design
- W7ZOI Crystal Filter paper has several crystal filter designs
- Narrow bandwidth bandpass filters for SSB
- Used for transmit/receive
- 9 MHz nominal frequency
- Bin crystals using Colpitts Crystal Oscillator
- Hand select close values from a pile of crystals
- Can get much closer than 10% of bandwidth with 50 crystals
- Crystal Filter Design - Other filter builds
W7ZOI SSB6 Schematic
My Build
- SSB6 filter is too big for Kits and Parts board
- 2500 Hz bandwidth
- Fits in 80x50 extruded enclosure?
- Too tall???
