ps.: regarding the antenna
Low power requires a good antenna. In the picture, I highlighted in red where the wire goes. The highest point is 10 meters, the two lower ones are fixed at 5 - 5 meters. With this delta loop antenna, I can use the device on 7, 14 and 21 MHz without an antenna tuner. The horizontal section is fixed at a distance of approx. 20 meters. Since I have a small area, this seems like a good solution.
Important: I often have to change the location of the transmission frequency, because the 100-watt weak signal stations suppress me. I note that I have managed several dx qso's using this method.
The log data only shows qso's made with sBitx.
