Bob, I knew that this type of mathematical analysis of the out of band signal was theoretically possible. However, I hesitated to mention it lest you guys get deluged with clamoring for its immediate implementation. You let the cat out of the bag, so you are responsible for the consequences....hi, hi.
In all seriousness, what you will be experimenting with is not an "out of passband notch", but rather an analysis of an out of passband signal which is causing in passband interference and using the results of that analysis to predict the characteristics of the in passband interference. A compensating signal could then be generated to cancel out the in passband interference. This approach, if successful, could theoretically allow interference-free SSB QSO's only a kHz or two apart. The prospects are mind-boggling. Good luck. I certainly wish you success! However, there is unfortunately still no benefit from an out of passband notch. 73, Ray, K9DUR _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
