[TenTec] Re: N4LQ and the 2.8kHz Pill

[Dr. Gerald N. Johnson, P.E.]

Tune it to ten dB down the slope of a filter, look at the output without
AGC. The filter slope will make a frequency discriminator.

Or look at with nearly zero beat, you should be able to see the change
in frequency if the beat frequency is low enough.
