I finally got my act together and built a transceiver. It's for 40 meters CW and has about 4 watts output. Some of the details may be of interest to other homebrew experimenters.
One of my motivations for building and Arduino controlled DDS-60 was to use it as the VFO for a QRP transmitter. I have had success with this by using the RF stages of the Universal QRP Transmitter Mk-II by Wes Hayward W7ZOI as described in QST April 2006.
