Reflections about a remote shortwave listeners station

That was quite a piece of work until the refurbished station was allowed to present itself as in this picture. The new heart of the station, a 7-port USB 2.0 hub with 12V / 5V seperate output, reliably controls the current flow to the ELAD FDM-S2. A new linearly regulated 5-V power supply ensures in the background that this works smoothly. The Trekstor Tablet still hangs on a conventional 5-V power supply without any RF interference detected so far. I used the opportunity to lay cables and devices even better than before. A downer remains: SDR-Console V.3 can not be persuaded to timed automatic recordings. It never stops with the station work. But first I'm happy that everything is up and running again - time for DX!

Meanwhile, it has become the beginning of March, and for a long time nothing has happened here in the blog. The trigger was the broken tablet, which was sent for repair at the end of November 2017, and did not return until mid-February 2018. It had disappeared

I didn't come to any solution working with this ext. powered hub. The Tablet didn't charge and run the ELAD FDM-S2 at one time. Following a tip I cut the ground line of the mini-USB-connector, but this didn't work either. It's reconnected again. I tried to connect 470 Ohm resistors in both data cables of the connector. (As described in Perseus_SDR Group)
According to the Perseus_SDR Group link the resistor should be set only between line A und B, but this does not work with the Tablet either. Connecting 124 kOhm and 36,5 k Ohm resistors (from: ... searchtips) in the same way did not work either. May be it's all bullshit.

At this time I dont see any chance to charge and run the ELAD FDM-S2 in parallel with this Trekstor Surftab wintron 7.0.

Just to confirm how the Trekstor Tablet works with the Logilink UA0140 Hub (without external power supply)

USB-in cable connected to power line
Connectors:
Pos. 1 Ext. HD 2TB = tries to connect but fails
Pos. 2 FDM S-2 = connected, but offline
Pos. 3 Tablet = charging
