[Elecraft] K3 dbV in 2.38

[alsopb]

Apparently I need some help in trying to use this dBV capability with on the
air signals.

For example, using it as an AGC off "relative" S-meter with digital readout
to run some antenna pattern checks for skewness etc.

I've used it just fine in "lab type" measurements with a constant signal
source.

First question.  What is meant by stable value of AFV?

Here's what I see for a bunch of AFV edited values one after another with no
change in K3 settings.
1579,1688,1598,1624,1696,1613, 2168,1758,1425.
The range is 6db.  

Is the reference value of AFV used in the dbV calculation the last one taken
at the instant one leaves the menu entry?  Yes, it doesn't really matter if
that values is used forever.

Suppose one then takes a series of dbV measurements,  is the reference AFV
ever changed during the set of readings?

The integration times available are 500 and 1000 ms.  It would seem that
longer integration times are required for off air type measurements.

Is there any integration time in the measured voltage used in the dBV
calculation?  Or is it nearly an instantaneous value?  For off the air type
measurements, it would seem that a suitably long value is needed.
