Reflections about a remote shortwave listeners station

Running a remote station means there is always something to do.

I checked the antennas after some storms and noticed that the top of the K9AY was broken. This looks like a difficult work in a height of about 8 m. I have to fix this in the coming weeks. Another antenna - the horizontal loop - doesn't work as good as before and I have to check if there is a cable break in only 5m height. [fixed: a badly connected wire]

Another duty is the connection of the big notebook, which consumes 5-7 Ah, to the solar energy circle. Connecting this notebook is not as easy as you might think. I bought a 19 V powerbank which delivers 2,5 h additionally to the notebook accu cell. But, for timed recordings with SDR Console software, the USB connection always failes if coming from a sleep state. This problem comes with Windows 8.1 and I don't know how to solve it yet. Another problem was coming up: the powerbank creates disturbances. So I wan't be able to record with the notebook. Very sad.

The Rocketec voltage converter is meanwhile broken, which is not so bad because it delivers always some noise on some bands. So returning to accu energy might be the better way. As you know the small Tablet can only run with a limited bandwidht so I am looking foreward to have a stable connection of the notebook which can run up to 6 MHz broad recordings.

I am also looking for falling prices of SSD discs to get more space on night recordings. My Toshiba 2 TB HD denies since some time to work properly.

Further plans are to connect another 100 Ah solar battery to the system and to get another 100 Wp solar panel. Charging the batteries with 1.5 Ah in average takes a long time, so a second panel and battery may help coming better through the winter. A WiFi-connection is also in planning which could mean to run the station really remote in some time from now.

Hope to get the right stuff on the Ham Radio Fair in Friedrichshafen and to see the one or another of you guys there.

Despite careful preparation arise ever new anomalies. What is the state of things and what happens next? Although hours of recordings can be made, but still the recording quality is poor. At some point stutters recording. I have not found a solution.

Another problem is with the power supply of the batteries. Not always accepted the HDD a power connection to the tablet. An irregularity I could not find.

The two points still take some time to complete. So, stay tuned to the blog.

After some searching and testing weeks, I have the right OTG cable found that works in both directions. A SAWAKE 4 Port Hub is doing its battery service and ensures that the data flow in both directions. This is a milestone on the way to my remote station. The OTG hub cable combo running at the moment still in test mode. Connected are an external hard drive and the ELAD FDM S2. The hard drive is powered by a power hub with the SAVAGE 4 Port Hub. Audioengine D1 is apparently not supported by the USB output.

However, an unsolved problem always means that more arise.
