Help - Zero Beat

[James E Temple]

Hello,

Adding to Bob's question, I have had the same thoughts.

Some signals will go from a tone, to silence (zero beat), to the tone
again as the dial is moved in one direction.  With a cal tone, the
sequence seems to be silence, to a tone, to silence as the dial is
moved.  The last example is where I am uncertain where zero beat is, since
there is no silence (null) in the tone between tones.

Thanks for any help and advice.

Sincerely,

Jim

However, I am trying to align an HW-101 and there are constant references to zero beating the receiver to either the calibration signal or a known frequency. Since there is only one signal, say the 3.7 MHz cal signal, how do I zero beat the receiver??
