[Premium-Rx] interesting HF design site

[refmon]

Hi group,

I've just stumbled over an interesting site, KEL Aerospace, which contains
some very interesting HF receiver, modem, etc design discussion.  Of
interest to those who survived the beloved days of the "woodpecker", see the
area on OTH receiver design and specs.  Go to:
http://www.kel.com.au/index.html .

happy browsing and fiddling,
