FW: [Elecraft] Spectrogram plot interpetation

Hi Dan:

I believe that to be an artifact of Spectrogram and the sound card! I've 
noticed something similar in just about every Spectrogram presentation I've 
seen. I do not believe it to be present IN the K2, or whatever rig is being 
tested.

I saw it, and didn't even consider commenting upon it because I've seen it 
so often it no longer stuck out like the sore thumb it appears to be.
