DAB experiences welcome // DAB+

Hello together, I would be interested in what experiences you have had with DAB. I live in NRW / Remscheid and here is actually one of the best areas from the coverage. However, my experiences are rather mixed. I drive my new elk since mid-July. At first I had a super reception – e.g. 1Live comes over in a very good quality. If you switch between DAB and VHF a clear difference is audible (1Live has on VHF in this comparison auc h had a good reception). The reception was only bad with DAB when I was in Cologne under the cathedral in the parking garage! However, I noticed that I didn’t have a reception at all late in the evening / at night – and indeed from no transmitter. Is this all still running in the test operation? This morning station search started and the result were several mostly foreign stations with poor reception quality. Does my radio sound? Or are you just as dissatisfied? I also heard, that DAB+ is only a new codec, which should guarantee good quality even at lower bitrates. Does anyone know if the currently delivered radios already support this codec? Germany is well known in European comparison rather a developing country – at least when it comes to digital radio reception.
