I said:
Depending on whether you have the pre-amp on or off, the K2's audio
changes as much as 40 dB over an input range from -120 dBm to -20 dBm.
Under those operating conditions, the AGC works at about a 2.5 dB : 1
dB, RF to audio change.
I did not mean that statement to imply that the audio output to RF input
transfer ratio remains constant throughout the 100 dB input range. It's
definitely non-linear, as the curves at
