I plotted the carrier of 1400 CBG on Spectrum Laboratory today between 0930 and 1930 UTC
Sunrise here is around 0708 and sunset 1628 Distance to Gander NF is around 3400 km. http://paulc.mwcircle.org/cbg.jpg The yellow trace showing the frequency of CBG is undulating. It only faded out for around 90 minutes (1230 to 1400) and even then there is evidence that it wasn't totally lost. Amongst the random dots showing the carrier has been lost you can trace a few dots following the line of the CBG carrier. I'm not quite sure why the noise (red) is so much higher as the evening wears on - possibly the dreaded DRM on 1395 kHz. The green trace is the measured strength of the CBG carrier.
