Bill:

Forgot to add:    HOOK THE ACVM ACROSS THE OUTPUT LOAD RESISTOR.

The sig gen impedance (Z) should match the Receiver input Z, and the audio 
output
of the receiver should be terminated with a load resistor to match the 
output Z, say
500 ohms, or whatever.   (usually not 8 ohms in old days)
