[Elecraft] [K3] dBV display

[Don Wilhelm]

Julian,

You moved too quickly through the AFV display.
The way dBV works  - it provides the delta from the last stable AFV value.
Go to AFV and wait until the value settles down, then move to dBV and 
you should see a value very close to zero if the audio is close to what 
it was when you were on AFV.
Now rotate your antenna, or change antennas, or or switch between 
whatever you are comparing, and you should see the variation in dB.

To be meaningful, dBV should be used with a steady signal source (unless 
you want to indicated the varaition between two signals).

73,
Don W3FPR
