This is a list of radios that I have built. There are separate of other things that I built. This page is only to list the radios.

• BITX20 : This is quite a popular design with variations build around the world. This is the original paper that described the radio.
• A 40/20M SSB transceiver: This was the first transceiver that I designed in 2003 that was based on the new set of techniques set forth in the Experimental Methods in RF Design.
• JBOT – A QRP Linear : We need a linear amplifier for most of our radios. This is a good building block that gives 5 watts of power.
