Not useful: whistles and has poor reception

After I tested five pocket radios, the antenna on the Aux cable had only moderate reception in the car, I have tested this unit because I had hoped with the separate wire antenna for better reception. The opposite is the case:

* The power supply via the cigarette lighter on the radio very loud whistles in time with the spark of the car
* The reception of the antenna is very bad, no matter where in the car they interpret

Instead, I have now bought the Albrecht DR56, which is worlds better. The there mitgeliferte glass antenna has perfect reception even if it is just igendwo in the car. And the sound quality is also much better, without Pfeifen.Das DR56 is the only DAB + car radio that works well.
