I presented a talk on my entry into the ARRL Homebrew 3 challenge at the MIT Haystack Observatory a few weeks ago.
Here is a link to this talk:

Photos from my visit to ARRL HQ on 10/31 to drop of the homebrew challenge 3 radio:

Plugged into the 10m broadcast beam at W1AW, made several DX contacts that day.
Schematics for my ARRL Homebrew Challenge 3 radio, a 6 & 10m SSB/CW 60w radio, have been posted to the web.

If you build something cool from these, or a more improved radio, i would enjoy seeing your work.
