Whilst fiddling with my 850S, I noticed on some modification pages a way to get the filter out for the broadcast band. Aha, sez I. I could use the thing to copy VLF signals (160khz or so). Anyone ever try that? I suspect that I would use it for about 2 days, undo the mod, and go back to 40 cw, but I haven't had anything that would cover those frequencies since the Setchell-Carlson days. 73 jerry w8gnd
