VFO This is the story of my quest to build an all-tube VFO for 26.0 to 26.5MHz, for use in a 21MHz SSB/CW superhet transceiver with 5.0688MHz intermediate frequency (IF). Construction efforts below were assisted by advice and commentary by G4OEP, K3IMW, K7HKL and VK6JY.

Radio, Electronics and Computing Projects
by Hans Summers

I make no claims for technical accuracy, good design, or necessarily even originality for the contents of these pages. Rather, I am a simple enthusiast attempting to convey my love and enjoyment of radio, electronics, and computing and perhaps to inspire YOU to build something too. The following pages document projects that I have built over a period of 30 years. Wherever applicable I have named sources and references. In each project I have attempted to provide as much information as time and resources allow, but no responsibility can be accepted for inaccuracies or omissions. Likewise, where some of the projects use mains or high voltages, no responsibility can be accepted for death or injury sustained if you attempt to replicate these projects. BE CAREFUL! If you have any comments or suggestions, please email me.
