[Elecraft] Analog Notch

[James R. Duffey]

Don - You are corrrect about the DaTong analog notch. I have an FL-3 and the
notch is as fast and deep as any of the DSP units I have. It is a marvel of
analog engineering. One really has to hear it to believe it. Everybody that
I have demonstrated it to has been impressed. The only downside is that it
will only handle one carrier at a time; most DSP units will handle several.
I am not sure why this technique isn't used more. Tong was very protective
of his circuits though, so that may ber part of it. - Dr. Megacycle KK6MC/5
