CFH made one peak (only at 24dBuV) at 0100z here and then dived into the noise for the rest of the night. Brian's plots show reduced levels on the single hop path to DCF39 but obviously not as dramatic. Brian's plot also shows about 3dB reduction in the normal daytime levels on Sunday, but with very little evidence of multipath so I presume this is increased absorption. Mid-day levels into Europe may improve and be enhanced over the next few days whilst the after-effects decay away. I would expect the poor night-time levels to last for about 10 days or so. The "short" sea path to Newfoundland seems to be able to carry Joe's signals across even under poor conditions.
