Simple Audio Clipper

I've seen the dual diode audio clipper circuits in many a QST and other publications but never tried it before now.  I saw this circuit in a Hint and Kink from February 1966 QST page 70:

The only change I made was to use BAT42 Schottky diodes.  This results in a clipping level of about 400 mV peak to peak as shown here (WWV on 10 MHz):

The idea is to protect your ears when using a receiver without AGC.  The limiting action is fast:

Unlike an add-on audio AGC where there is often overshoot present for the initial cycles.  With RF AGC overshoot is less of a problem.
