HF Transmitter Schematics

Seeing as i have not the money to buy a full functions super kick-butt radio, i have been looking for schematics and fell across this page, http://www.ac6v.com/homebrew.htm, as i browsed the links i found this link, http://www.vanyi.net/homemade/homebrew-hf-ssb-transceivers/#20m-14Mhz-transceivers. I found several good xsevers and many DSP and multi-band rigs, but i still want a extremely easy to build radio that i can fit in a small project box or in an altoids can, and an antenna with a small footprint when packed and one that is easy to put up. The idea for the whole project is to get a lightweight xsever and antenna for under $50 and hopefully less.
