An RF-Systems Magnetic Longwire Balun that has not been available for a long time has found its way to me. In future, this will be used as a universal HF antenna with a 78 metre long wire.

Band-Pass Filter 500 – 1700 kHz.
The perfect MW band-pass filter 500 – 1700 kHz for pure mediumwave reception. A very good filter at a good price from Greece. https://www.sv1afn.com/en/product-category-4/mw-band-pass-filter-500-1700-khz.html
Antenna work.
Today I mowed 200 x 1 meter under the Beverage with the brush cutter. You have to really earn the good reception.
Summer can come.
Thinking about summer today: Insect mesh and fan installed. The fine mesh keeps all the fine dust from the meadows away from my PC fans, and the large fan managed to cool the air in the container by 2 degrees in 20 minutes in today’s test. This will come in handy in a few weeks’ time. The fan blows the air out of the container and the opening on the container wall was covered after the photo was taken.
Antenna Disconnect Switch
My new ADS – an antenna disconnect switch to protect sensitive radio equipment from atmospheric overvoltages is finished. Thanks to Günter, DL4ZAO for development and documentation and to Rainer Bernedo, DF6RB for a perfect job. https://dl4zao.de/_downloads/ADS.pdf
Perfect Remote Audio.
I have now separated picture and sound from my remote PC, continue to use AnyDesk to transmit the picture from the PC at my station, but have switched off the audio transmission and use a small solution from a German radio amateur: RemAud – Remote Audio Software from DF3CB. This free software (but you can already send him a few stones with PayPal) is tailored exactly to our SDR requirements, can be set in many audio codecs and delivers an extremely good audio signal in 22 kHz PCM, 16 bit, for example, absolutely no comparison to the audio signals that come directly from the remote programmes like AnyDesk or Team Viewer. Of course, you can also use only 8 kHz with 8 bit, but this is often not necessary – but it is possible to save bandwidth, you can then transmit audio at less than 15 kB/s.
Beverage End Point.
The end point of the two-wire beverage. The springs keep the wire under tension but can be stretched up to 20 cm so that the wire cannot break under storm and ice load. The terminator is located in the box and at the bottom you can see the earth electrode where the buried radials begin.
Mid-February Beverage.
Mid-February at my station. The 200 meter Beverage has survived the winter with lots of snow and storms absolutely unscathed, everything is as mechanically sound as the day it was installed.
Stormy autumn weather
PA0RDT MiniWhip.
Worked on the station again yesterday. The 50 Euro original PA0RDT MiniWhip antenna is mounted on a 2 meter iron rod and grounded at the base. To the right is the starting point of my beverage antenna and the underground cabling to the station. The MiniWhip works excellently, the relatively low rod was deliberately chosen because of the strong storms at my station. However, the signals are perfect due to the free environment.
