Reflections about a remote shortwave 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.

A new project was started this week, the construction of a K9AY array with adjustable termination resistance, controller unit and relays. As you can see in the picture, the mast still causes problems. The heavy pole should be mounted nearby the other tree and still has to be passed by the tree crown. The white seat in the middle is the directors chair.
