Why radio doesn't work
Construction phase
Ok, you have studied physics, learnt about resonant circuits, learnt
how radio waves are propagated and you are fascinated by radio waves and
how they can transport data signals (such as audio or video) over long distances.
You have attempted to build a small transmitter (to broadcast illegally)
or receiver circuit. You followed the plans and made a circuit board, spent
hours soldering everything together. When you powered the circuit up, nothing
happened. You did whatever you could think of to get the damn thing to work,
but it would just sit there, not working.
Sounds familiar? Well, nothing strange going on here, it's just the realization
of Murphy's law!
1. Radio itself is a flawed concept, it does not work
When I mention radio, i mean the sort of radio you read about in physics
text et ceterea. the kind of radio that is easy to understand and should
be easy to buil circuits for. Well, I am about to present for you the reality
and the truth behind radio.
2.Radio is precisely the sort of thing that works in theory, but never
in practice
This second rule follows as a direct consequence of rule 1 above. It is simply
not possible to build a working receiver / or transmitter, since it is impossible
to get the circuits to work. Radio circuits follow the same principle as
gear wheels, which leads us to rule number three.
3. It works as long as the whole construction is massproduced and made
by machines.
This might seem like a contradiction, but it is in fact not. Have you ever
tried to build a radio circuit and did it work? Do you have a radio at home
which works? Beginning to understand now, what I am talking about. To novices,
television and such similar utilizations of radio signals appears to be
magic, and this initial intuitional understanding of the subject is crystal
clear and spot on - it is exactly that - magic, and you shall under no circumstances
try to build anything on your own - you are doomed to fail.
And then there is this mess with resonant circuits. Tank circuits (LC) and
their alikes, they never work either. Oscillators are impossibilities and
all other crap too. Simple common emitter amplifiers though are nice little
constructions, they work and are reliable even in practice.
Note that this page only presents my opinion and may change when I get my
morse transmitter / receiver to work.
