"Communicate, and Violence Disappears"


This chapter is about various radio-amateur subjects, not covered elsewhere but still interesting to know

Select one of the following subjects:

o                Notes on antenna tuners


o                Aspects of HF power amplifiers


o                Where does the HF power go?


o                R S T reporting code


o                Atmospheric noise


o                Ri is Ru ?


o                Why 50 Ohm?


o                Why '73'


In every life we are easily playing with familiar concepts that are not really understood when going into details. 

This also applies to subjects in the radio-communication world and when recognized may lead to exploring the

subject and more of the backgrounds. I welcome your additions and remarks and anything else you think

interesting to raise to this subject.
