 In the age of 'music streaming', terrestrial radio listening seems antiquated. In the absence of WLAN or mobile communications, however, it can be an alternative to stay connected to the world, at least while consuming. FM (UKW) transmission was first trial took place in Germany almost 100 years ago (1925). And actually FM was supposed to be discontinued in 2012, but this only became reality in the cable network. To the delight of motorists with conventional analogue radios. The current digital successor DAB+ (the previous, incompatible and not very successful DAB was discontinued) is at least visible on the market and there are a number of inexpensive DAB+ receivers under €30. I decided to try out a TechniSat TECHNIRADIO RDR: In the age of 'music streaming', terrestrial radio listening seems antiquated.
