DAB+ technology – conclusions

DAB works beautifully in Krakow. Great dynamics, some stations transmit slides showing album covers that are currently being played. Very nice gadget pleasing to the eye. Listening on headphones is sensational. I think technology does not develop quickly. A pity, because the technology provides a great listening outside major energy savings (less transmitters one transmitter gives some programs and not, as now one transmitter, one program), protects the environment and ourselves from excessive electromagnetic radiation (EMR), less radio transmitters are also less needed for their air conditioners cooling. So is the economic and ecological but in the broad sense. German studies accurately describe these savings and ecological aspects.
But, there is always a but, as you can see that the FM is doing well, and probably not soon, if at all will be replaced by digital technology. Receivers are now very expensive and this is what appears in the shops is rather old class tranzystorków” from the 70s. I saw recently a Sony in MediaMarkt for 280 PLN. I think this misunderstanding, a little mono radio pocket and so expensive? Something „serious” need to import from Germany. Although there too that too much is not. But the prices are.

A few pictures shows radio Technisat DigitRadio 500 that uses DAB+ technologies. Software has a few bugs e.g. with translate to polish language descriptions doesn’t fit in frame window. Radio has a little long time booting after push down power button. Better is disconnecting power cord from power socket and plug on again.  The radio has neither headphone socket nor 3.5 mm line out.
