Re: Building a Spitfire transmitter kit
I made my Spitfire a bit more useful by housing it into a sloped front box.
A dual hex thumb switch allows easier frequency change and makes for a useful sig gen for aligning at the more common IF frequencies. I also added an optional phase shift oscillator and extended the tuning components together with a ON-ON-ON switch for easy adjustment of the output.
