Reflections about a remote mediumwave listeners station

The new K9AY with extended circumference has a height of 9.50 m, the single wire a total length of 26 m, which corresponds to a limb of 8 m or 5 m. No problem was the erection of the mast. Most of the work fell as wires had to be entangled and the almost ailing tree crown was felled. A first hearing test showed that it is not worse than v1.0. The freestanding position without disturbing tree crowns, better copper lines, improved grounding and other dimensions provided a more rounded sound picture. Better separation accuracy and better forward / reverse ratio are the decisive factors in my assessment.

The masthead of the tree on which the two antenna wires of the K9AY crossed broke at one of the last storms. The reconstruction is now done with stable material and even better antenna wires. The felled tree will also serve as a "scaffold". It is sheathed over a length of 4 m with a 75 mm HT pipe (plastic water pipe) and is thereby brought to a total height of 9,50 m. It replaces the original height of 7.50 m. This results in other lengths, namely longer wire lengths.

The 1mm green coated garden wire is connected to a classic beverage antenna matching set with 50 Ohms from / lowbandsystems.com /. It is a directional antenna which should be good on NA stations. First tests shows it's good working - also in the opposit direction East Africa - and some dB improvement compared to the K9AY switched into a NW-direction.

Welcome back to the blog!

Up from now there will be regular writing intervals again on the built-up of my remote garden station.

I used the HAM Radio Friedrichshafen to complete some gear which was missing. At the moment a couple of items wait for use in the station. A few changes in the antenna construction have been set due to mount problems.
