Andrew, It might make a small difference, but you can work around it - assume the crystal set is 3.7 (the most common) and set the BFO frequencies initially from that setting. - Those values will work but possibly will not be optimum. After you have a functioning receiver, you can use Spectrogram to set the BFO frequencies so that the center of the passband is at your chosen sidtone pitch and all will be well. See my website www.qsl.net/w3fpr article - Step 3 of K2 Dial Calibration for detailed information on setting the filters and associated BFOs.
