[BC] Frequency Measuring

[Bill Croghan]

	Very good monitoring equipment.  All he needs is a detectable
carrier, not broadcast quality listening.  The 1 kHz tone is to provide a
reference so he knows he's listening to the correct signal.
The same way the FCC measures the carrier of a Single Side Band signal
that's down 60 DB or so from the main.
