Hî,
Thanks for the tip ! Unfortunately the tuning circuit which was included in my set has only a rectangle coil form.
What also surprised me was the fact that the bar antenna has no litze wire, only solid copper wire. The same wire was also used in a legacy block.
I thought that the litze wire has better qualities concerning stray capacitances in HF circuits.
The litze wire is used in the tuning block.
many greetings
