There were exciting days on the medium wave. In addition to the usual stations from South America such as Radio Bethel, Vaughan Radio and Radio Buenos Aires popped to sunrise other rare stations from Argentina, Peru and Bolivia. Also the Harbor Lights of the Windwards can be regularly recorded at 1400 kc.

Here is my complete logbook of the last days:

As in the last 3 years, there will also be a visit to HAM Radio in Friedrichshafen this year. The antennas call for further improvements, cables and plugs have become scarce. In short, there is always a reason ... if only to go on a long bike ride once a year. I look forward to a personal exchange of experience.

CU on HAM Radio 2019!

A small but fine opening to Peru I could observe on 11.5.2019 between 0315 and 0400 UTC. Although the signal strength was consistently weak, there were 5 new stations for me.

Excellent propagation conditions on the lower bands brought strong signals in the X-band and below in recent days. In the time around sunrise, around 5 o'clock UTC, it was really fun for a long time to hear Radio Monumental from Quito Ecuador at 1510 kc. But also WPTX from Lexington Park, Maryland at 1690 kc and WGIT Faro de Santidad, Canobas, Puerto Rico at 1660 kc were very well received for some time. Outstanding was also the reception of ZYO701 Radio Roraima from Caracaraí, Brazil at 1390 kc. All logs were made with the K9AY switched to NW.

Next Unit of Computing → NUC:

Power consumption is ~15 W, 1,25 Ah at 12 V without Monitor. Running SDR-Console in recording mode with ELAD's FDM-S2 is up to ~20 W, 1,66 Ah. In this mode with the connected Monitor and under WIN 8.1 energy saving mode the consumption is ~30 W, 2,5 Ah. This is more than expected but less than the 90 W 4,74 Ah notebook. The BIOS is capable to WOL (Wake on LAN). This is not possible with the notebook. Also recordings can start out of sleep mode under WOSB. In this mode the USB port for the SDR is off and does not waste energy as it was with the notebook in energy saving mode. Waking up the notebook from sleep mode with WOSB was not possible. The device makes a solid impression; the case is made of metal and cleanly processed. The boards are clearly arranged and properly wired. The operating temperature of the fanless system is 42° under load with the SDR Console.

Monitor:

The screen ist only accessable under a running Windows. This means that access to BIOS and other functions are never available. Due to the low power consumption and no alternatives I decided to keep the device. If something goes wrong the NUC will be handled @home. The monitor has a direction sensor and adjusts the image according to its position. The screen comes with a HD resolution of 1920x1080 px and a fine viewing angle of 180°. To keep the length of the USB cable short, he spends his life standing upside down and mounted in a frame on a wooden wall. The controls are also easier to handle in this position. The weight of this device is 800 g. It is one of the thinnest monitor on the market with 8,5 mm.

Both:

RFI on some QRG's on MW, seems to be irregulary and "adjustable".

All in all:

Better audio or less RFI compared to the notebook. Can be fixed with screws on the desk. A very good performance due to less installed software, i7 Kaby Lake prozessor, 8 GB DDR3 RAM, SSD and 64 Bit OS. It is the fastest device I ever had. Manufacturing & delivery time from Taiwan was ~14 days due to 春节 Chinese New Year 2019, the year of the 猪 Pig. First tests showed no delays in automatic recording. All devices are working perfect together.

The cube has fallen: alea iacta est, as it is called in Latin, if after a long time a decision has been made. In more modern times translated: the winner is a 15.6-inch mobile HD TFT LED screen of the Asus MB 169B+ Brand with a power consumption of 5 watts at a weight of just 800 grams. Although the USB-controlled monitor significantly exceeds my price limit, but also put all the other monitors in the selection, due to the low power consumption in the shade. An interesting effect of the weeks-long search was that smaller monitors tend to consume more power, or the size of the monitor is not necessarily crucial for power consumption. Originally I was looking for 11.6 and 13.3 inch monitors. Only the search for larger models brought me into the optimal power range. Furthermore, the German market is hardly well covered with smaller monitors, which is why I initially searched the Chinese market of a large provider. Another reason to buy locally around the corner was that in the case of warranty the effort is low. Although the previously purchased NUC comes from China, but here I trust more on the longevity of commonly used hardware components. And yes, the monitor has a drawback, of course: due to its small depth, it can not be obstructed against the wall. So here again handmade is announced. The egg-laying "Wollmilchsau" has not yet been born.

The next step is the search for a suitable Ethernet to WLAN bridge for the NUC, so that the small one can be switched remotely even when switched off. This should then be the last search, because a keyboard for the Mini already exists.

He is not yet set up, but he should secure the future of the station. A fanless NUC with i7 processor, 8 GB RAM, 256 GB SSD, WiFi and all possible connectivity is on the way. The decisive factor for the investment in new hardware was the fact that it further reduced the power consumption of the solar-controlled system and also enabled real remote DX. The supply voltage is 12 V; a disturbing power supply is no longer necessary. The mini-computer should consume 15W, a halving of the power requirement compared to the 17 inch notebook. A wireless Wi-Fi connection to a server near the site then takes over the remote function. The latter is so conceived, but whether the reality plays along, is first left undecided. WIN 7 will control the plant, and Teamviewer will connect two PCs. First, as usual, everything has to be tested, and that will happen in the home QTH. At the moment the decision for an external monitor has not yet been made. I'm curious to see how many new RF interferences I have to contend with soon.

One year is long, and sometimes it's better than the previous one. What does the station look like at the end of 2018?

The question is not easy to answer. I had to fall back on the notebook after the failure of the tablet. In a 220V environment no problem, but in the 12V mode, you are constantly confronted with run-down solar batteries. The solar system could be expanded to 10 times, and even then I would not be safe from failures. Therefore, I will keep the plant in its current status. But the reasons are elsewhere. The 12 / 19V voltage converter causes slight disturbances in the MW range here and there. They were not available in tablet mode, because the power was converted from 12 to 5 V with a length-controlled power supply. That's why I plan to buy a 50 Ah Lion battery in 2019. He should supplement the existing 22 Ah Lion battery. Together with the notebook battery, I would then come to a running time of 5-7 hours. That is still little, but a bit more comfortable with a corresponding operation.

The mediumwave band from 500 to 2000 kHz in the early afternoon. The formerly low-interference remote location is developing into a HF-picket fence. It looks bad, the disturbances can often be excluded by sidebands. If the signals attract, so after dark, you do not get too much of it. Only the SE leg of the K9AY hides the interference very strong. A disturber shuts off punctually at 17z.
