Maybe dBv stands for dB "variable," not dB with respect to a volt.
Not with respect one volt, but voltage based, using the 20log rather
than the power-based 10log conversion.
AFV is "AF Voltage" and corresponds to the voltage you would measure
across the speaker with AF GAIN set to max. Units are mV RMS, and
over-range truncates the MSD in the display (but is still accurate, I
think, over the serial port).
I no longer remember if this is with AF gain scaling set to H or L.
