Paul, My filter has the 2.5kHz capacitor values fitted. The bandwidth I get is less than that, probably 2.2kHz-2.3kHz. To my ear this is about right, and feel that anything less would start sounding too restricted. It also seems to give a good response curve for rag chewing and DX/contest operation.
I would recommend grounding the crystals at their bases, however be careful not to use too much heat or damage the crystal case seals. 73 Stewart G3RXQ On Tue, 15 Mar 2005 14:41:53 -0600, [EMAIL PROTECTED] wrote: > Hello All: > > I'm sure that this has been discussed many, many times, but would you be so > kind as to give me the pros and cons of the various filter options?
