To All

As requested by Jean-Jacques Delcourt, ON5PG, via Rik, ON7YD, I have measured the signal strength of GBR at about 16 kHz.

For comparison purposes I did the same on DCF139 at 138.38 kHz.

During the eclipse I measured every 5 minutes. Measurements before and after where made at random moments when I happened to be in the shack.

The antenna is a vertical with topload, untuned. The antenna was connected to the high impedance input of a selective level meter PSM-5 made by Wandel & Goltermann.

Bandwidth was 500 Hz
