[Elecraft] K3 Receiver Noise Level -- Evaluation and Adjustment

[Mike]

Wayne -

Could you explain the MDS test in greater detail? My AFV (AGC-S, ATT 
off, no sub reciever) value bounces all over between 18 and 62, with 
most values in the mid 20's. Over a 5 minute period, it doesn't 
stabilize. I don't know what that means.
