Radio Frequency (RF)
It all started with high frequencies: radio technology was the driving force of electronics. At first there were electron tubes and AM radio, later followed by VHF and FM. Now we work with semiconductor devices, and the frequencies just keep on rising. Nevertheless, RF projects for the medium- and short-wave bands are still extremely interesting, especially for starters.
