The valve radio in the picture receives from about 1Mhz through to about 10MHz i.e. medium wave to short wave. Picked up Beijing Taiwan etc after 6pm when they start transmitting. Uses a speaker not headphones. Circuit is my own design. This is my valve electronics prototyping board. Why valves? Because I am just a bit young to have really had to use them so this was more of a fun exercise!
