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?
