Due to this co-channel interference, the carrier of Radio Iceland is fading fast up and down a few dB (motorboating). The transmitter on 187 kHz has a stable carrier here and at daytime the level is - 101 dBm. 16 minutes before the eclipse the level dropped to -117 dBm. This dip happened in the course of three minutes. After the dip the signal gradually increased to -80 dBm at the time of eclipse. It stayed at that level for 3 minutes and than gradually dropped to -101 dBm at 10:15 UTC. The increase in signal strength was 21 dB. 73, Roelof Bakker, pa0rdt Receiver: PERSEUS SDR Antenna: pa0rdt-Mini-Whip mounted 5 meter high.
