Just a note that I just finished building
this small, inexpensive CW transceiver,
and it is terrific.

http://smallwonderlabs.com/swl_swp.htm

Hears pretty well, ridiculously simple to align,
stable after a few minutes warm up. All high
quality parts and PC board.
Fun to build, fun to use.
You'll have to find your own enclosure, though,
but the board is only 2.8" X 4.0".

I highly recommend this little rig for someone
looking for a small useful project to build.
I am adding a Pico Keyer Kit to mine,
an maybe a little LM386 audio amp to drive
a speaker as it is designed to drive headphones only.

Agree. I built two, for 20 and 40 meters. I'm not "the Charlie Daniels" of a soldering iron but the directions are so straightforward that both of mine worked right away. I run them off of a small 1800 mAh battery with an external portable keyer that I use in my other QRP rigs. For the money they are hard to beat and have very competent receivers.

Dave Benson is a QRP treasure as are his SWL+ rigs.  I have never built one that didn't work, and I have probably built a dozen of them for myself and my ham buds. I just don't think you can beat the value in a SWL+ rig.  I find half the fun is coming up with a "unique" enclosure.
