My Amiko Mini 4K Combo shows the same strength and quality on each transponder, i.e. at the level of 98%, even on a poorly receiving transponder with stuttering picture and sound. In the case of DVB-T / T2, this tuner shows different values for individual multiplexes. Does this symptom also occur in your Amiko Mini 4K Combo?
PS. When an external remote sensor is connected to the IR port, this sensor does not light up and this sensor does not respond. Does activating the external remote sensor on this tuner require some menu operations?
