[Elecraft] K2 Noise

[KD2JC]

I may have had a similar noise in my K-2 and had finally traced it to running
Ham Radio Deluxe while using an external speaker.  If I shut down HRD the
noise would go away, BUT with HRD on and using the internal speaker on the
K-2 it was not there.  I traced it to computer noise getting into the
speaker because of poor shielding of the external speaker leads.  Hope this
helps: 73
