Hi Ralf, Lyle explained how the dBV value is derived. It's a pretty useful measurement.
One way to use it is to disable AGC, then measure different signal levels. This makes dBV a linear measurement, up until the signal level causes hardware AGC to activate. Be cautious with your hearing when AGC is disabled. 73, matt W6NIA On Mon, 20 Oct 2014 01:45:24 -0700 (PDT), you wrote: >Hi, > >I have been playing around with the "dBV-Feature" of my KX3 for some time.
