I know of a nice company that sells custom made LPFs that will eliminate the images. The preferred method would be a pre-selector that goes down to those frequencies, but there is nothing that goes down to VLF frequencies. I am in conversation with someone who maybe releasing a commercial product soon. If there is a commercial vlf/lf pre-selector, I would like to know.

I know it was talked about but couldn't find it in the knowledge base.
