The load regulation of the transformer/rectifiers is also an issue.
Does Elecraft spec the load regulation of the KPA-500 at nominal AC input

I did not have the issue with a stock K3.
I sent my k3 into Elecraft for the Syn upgrade. Elecraft perform the upgrades
and the receiver now has his crackling noise.
I do not know if the noise exists on the sub receiver as I have not listened to
the sub during the crackling noise.

unning with AGC off, just leave the AGC on and if you
reduce the RF gain to counter strong signals, the AGC action will be
reduced.
I know old habits die hard, but the K3 is not the same as my old NC-100
receiver and needs to be operated differently.
