Here is a little project I am excited to build. The Gnat 1 by Chris Trask – N7ZWY. It is a ONE transistor CW TRANSCEIVER. I’ve seen other one transistor transceivers that employ a multi-pole switch or relay to toggle the transistor between the transmitter and receiver, but this one is unique in that it employees neither of those schemes. The key itself switches it from receive to transmit. This should be fun. If I am successful (or not), I will post about the fun time I have with it.
I just received some crystals in the mail today, so my attempt at this little project will be for the 80 meter band. Check this little project out and warm up your soldering iron and give it a try. It will be FUN!
Here is a six page pdf of the project from N7ZWY: http://www.home.earthlink.net/%7Echristrask/Gnat%2040.pdf
