[Elecraft] [K3] AGC THR and noise

2008-12-02 Thread Steven . Zabarnick
I'm somewhat puzzled by the behavior of the AGC THR adjustment with respect to band noise. My understanding is that the AGC THR setting adjusts the level at which the AGC is activated. Thus, I would expect when listening to band noise (QRN) that if the noise is activating the AGC, using a higher
