All-digital mode gives unexpected range of reach. Challenge to DAB+ and DRM+
An up to day successful trial with the U.S. digital radio technology HD Radio (IBOC) has started in Oslo managed by the Norwegian Local Radio Association (NLR). The station is Radio Nero on 98,7 MHz.
In contrary to the standard setup for HD Radio in the U.S. with the main channel in both analogue and digital mode this transmission is all-digital. Because of this the range of reach - with no signal loss - is surprisingly good even with this 100 watt transmitter in Oslo.
