Transmitter Circuit?
I am trying to locate the article for a simple 2 transistor topband AM phone
transmitter from many years ago that I am sure appeared in "Practical Wireless" sometime between 1958 and 1965. If memory serves me correctly, it used two germanium transistors, OC71 and OC44. The OC71 was configured as a microphone amp/modulator and the OC44 as a Hartley oscillator. The oscillator coil was wound on a short piece of ferrite rod. I wonder if anyone can help in any way? |
