You need to start with interest. You have it. And this is the main thing.

I will share my story with you. My acquaintance with radio engineering began in the late 60s, when, together with my friend, we found a Telefunken receiver in his shed.

The lamps were withdrawn from it, and without them, naturally, he could not work.

However, after conducting an audit of the shed, they found a box in which there were a dozen imported lamps. Immediately a guess flashed: probably they will approach our "Telefunken". But how to determine where which lamp should stand.

Six lamps are 1x2x3x4x5x6 = 720 combinations of their installation in the device. Taking into account the shutdown, installation of the lamps and subsequent switching on, this should take at least 10 minutes. That is, a simple search can take up to 120 hours or 5 days without sleep and rest.

How do you like this prospect?

And then, we remembered about Iceberg's book "Radio is very simple", which we saw a week ago in the hands of our school friend Vovka.

We read it avidly in one day. We did not read more interesting books on electronics then. The author expounded serious things in simple understandable language. His heroes Neznaikin and Znaikin charmed us. In short, we grasped the essence pretty quickly and immediately began to use the knowledge gained.

Here our ingenuity worked. Sequentially, going through the entire chain from the input of the receiver (antenna socket) to its output (huge speaker), we first identified the nodes (input amplifier, local oscillator, signal detection, LF preamplifier, final 2-cycle amplifier).

Then, by the appearance of the lamps (size, base and design), they guessed their purpose. To summarize, the entire procedure for solving our puzzle took about two hours.

And then a sea of ​​true plantation from high-quality reception of radio stations in all wavebands and excellent sound by the standards of that time.

Most importantly, we could listen to: The Beatles, Led Zeppelin, Roling Stouns and many other foreign rock performers, as well as the programs "Radio Freedom" and "Voice of America". My barn has become a musical mecca of foreign pop music and a "gulp of forbidden foreign information." This is such an unforgettable experience.

This story was continued by my passion for radio. I read all of Iceberg's books, including Transistor - it's very simple! "

I began to make transistor receivers for myself and my family.

And, finally, I firmly tied myself to radio when I entered the Bauman Moscow State Technical University in 1973 and graduated with honors in 1979.

I devoted more than 40 years to this profession.

And I never regretted my choice. I am sure you will not regret it either.

I wish you all great creative success.

Practice, practice and more practice. The only way. Come up with something simple and google how to implement it. Do not use Arduino, or at least run it in C.
