For this connection, you need a high-grade, shielded USB 2.0 cable with USB A to Mini USB B 5-pin (see Aaronia accessory list). Note: We strongly recommend using our own custom built USB cable as these incorporate especially developed EMC shielding and thus drastically reduce any possible interference.
Note: You can also connect other DC power sources with an output voltage of 12V, using a 3.5mm phone jack. Polarity of the jack needs to be as follows: The “inner conductor” must be “+”, the “outer conductor” must be “-“. www.aaronia.com...

This is completely normal, as the signal strength of the high frequency radiation also constantly changes. This also depends on the alignment of the antenna.
