thanks for the pointer to the japanese homebrew page.
those are incredible projects! very much Olde Skool
"makin' due and gettin' on with it". A lot of cleverness
in those designs. the 40mSSB to MW-AM converter is
*brilliant*. one could imagine putting that in
a little box for some very amusing Ham band SWLing
with "found radios".
thanks again!
