Elaborated answers for radio amateur exams

When preparing for radio amateur exams, it is difficult for interested parties to obtain comprehensible documents, from which they would understand the issues of electrical engineering and radio engineering. I mostly deal with the background, which are indeed correct, but incomprehensible and often outdated for the self-taught.

TIP – personal preparation for exams

This summary of materials includes 51 A4 pages. Pages of other materials and books are certainly added to this. However, many things can be understood very well with a practical demonstration with a radio amateur or electrical engineer. If you have the opportunity to prepare for radio amateur exams with someone in person, definitely use it!

Informal answers for radio amateur exams

Why informal? That's why I prepared answers for a friend as part of his exam preparation some time ago (successful). They are written in a personal style so, as I expected, that they will suit his knowledge, but they do not have to be elaborated in the required depth by the examination committee. They are just a guide. The material did not even pass technical and language proofreading, so its use is at your own risk.
