[Elecraft] AGC

[Don Wilhelm]

Dave,

Yes, AGC settings can 'enhance' the receiver noise if set incorrectly.
When testing AGC setting, listen not for the signals themselves, but to 
the pauses in the signals.
For more guidance on choosing the right AGC settings for your condition, 
check out the "Noisy K3" article on my website www.w3fpr.com.
