I built my K1 years ago, but I also just re-read the K1 manual, yet I still do not quite understand how to adjust the Xtal filter's bandwidth to center on my chosen sidetone frequency of 500Hz. (The way I check the K1's xtal filter's center frequency is to display the K1's audio output noise into a PC's spectrum analyzer, as shown below).
