This is me, on my birthday in 1959, four years before I managed to build my first (probably highly illegal) Medium Wave transmitter out of a portable transistor radio. How I managed to pull that off will stay a mystery forever. Luck was the major factor, I guess, together with some instinct. What I do remember is that I made use of the oscillator properties – tuning 455 KHz down on the transistor radio produced a carrier on the big Philips AM valve radio I had in my bedroom.
After some (even more mysterious) modifications and the addition of a very long piece of antenna wire, this ‘transmitter’ was able to serve one block of houses. I modulated the thing with a carbon microphone, which I
stole borrowed from my parents by disassembling their phone. From that point on I was hooked.
