If you operate the radio with a headset, it usually has good reception. If you put an Aux cable to the radio, the reception is still good. But as soon as you plug in the other end of the cable somewhere, eg to an amplifier, an active speaker system or to a car radio, the shield of the cable is grounded and the reception immediately interrupts completely a. LED signal strength indicator is based on full-scale return to near zero. Thus one erhät car patchy reception, ie with interruptions.
My recommendation: When headphone radio for Running the unit is ok, for connection to an active speaker at home or on the Aux input on the car radio via an Aux cable but rather less desinged.
Among all getesten Tasch radios this device, however, is still the best. It is very small and portable, has a good screen that displays battery charge, signal strength and text information simultaneously. Compared to other radios (Pure Move, Aves Air, Grundig Micro 75, Technisat GO) has this Technisat mobile still the best reception and the best overall impression.
For operation in the car I have now bought the Albrecht DR56, which is supplied with a separarten disc antenna outside the Aux cable, and even inside the car has perfect reception.
The Technisat mobile I will possibly keep as a compromise solution for the second car. If you do not want a permanently installed radio with power, Auxkabel and separate antenna, this device is probably the best alternative.
