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.
