Theory question please? ? I'm preparing to sort crystals for the 12 MHz SSB filter. ?This will be my first crystal filter. ?I expect I may have to adjust things a bit as a result of the different crystal specs (but I don't know this for sure). ?I don't know exactly what/where the pass band should be. ?12 KHz center on 12 MHz? ? (Or is the filter design tolerant enough that I can just build it and it'll work?)
Thanks!
