Hi,
I was wondering if any of you fine people can help me understand a few things about Howard Armstrong and Harry Houke's superhet radio receiver built in 1924. My fist question is that they used a second harmonic and I don't understand why. Where was the second harmonic used and how did it help?
In addition, I read a description of their design from a Radio News article from May of 1924 where they have a simplified schematic with 4 triodes and then write that it was great because it only used 6! Where are the missing 2 triodes?
Thank you so much,
Kathy
