In this project me, Tom and Emilio made a FM radio transmitter that had a range of about 100m. This
was
done
using an harmonic oscillator @107Mhz and a
varicap which changed the oscillating frequency by about 40kHz. This project started of as a real
struggle since
these high frequencies come with
all kinds of paracitic charactaristics. This meant that even a piece of wire could be considered as
an
inductor.
However, we did get it to work and it was
worth it. It is kind of surreal that when you take a random standard radio it plays your music if
you
tune into
the right channel. The final product is displayed
next to this post.
I have done this project with Tom Brunning and Emilio cuertez in order to finish Module 3 of
Electrical
Engineering on the University of twente.
