The connected 55 Ah car batterie delivers electricity for about 5 hours. The current flow then went down from 19.5 V to 17.5 V. The notebook electricity changed for that reason with continous beeps between external powered to accu. There should be more power available. The max. notebook need is 4.74 Ah, so this batterie has to be changed or charged again after that time. To prevent discharge of the battery, a voltage monitor will be switched between, next.
The Rocketek voltage converter radiats HF of about 10 dBm between 6 and 30 MHz. The tropical bands and medium waves are clear as without a converter. I will try to add some ferrit to the charging line next. On some low frequencies are wobbler to hear. It could have been worse. The device was bought blind.
On the picture you see Audioengine D1 above the ELAD. This device delivers digital audio through USB and is classes better than the notebook built-in audio chip or card. Particularly at low incident transmitters he brings a barely surpassing clarity. Another pleasant advantage is the volume control by hand.
