In the ladder filter that Tentec uses, the crystal frequencies determine the center frequency, while the capacitors determine the bandwidth. The larger the capacitors, the smaller the bandwidth. Ther

Hi Tom, Aren't the crystal frequencies in the CW filters much different than those in the SSB filter? I always thought that the crystal frequencies were the main determinants of the bandwidth. The sp

I am going to try to tighten up the spare Argosy/Corsair I 4 pole xtal filter from 2.4 kHz to as close to 500 Hz as possible. If someone out there could look at a Model 217 or 219 CW filter and let m
