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
