Hi Jacek, interesting but there is no real cause for absorption at present, and it would not affect groundwave. However there was a flare this morning at around 0400 0500z . This would have enhaced the skywave ay 225kHz and perhaps lead to destructive interference with the groundwave??

My DFCW-60 window is almost dark in the moment. [...] there seems to be increased absorption right now, maybe due to solar x-rays. i've just tried to show my daughter how a crystal radio works, and can barely receive Warsaw 1 on 225kHz (with active antenna and tuned circut). normally i would receive several stations with just a diode and low-impedance headphones. jacek |
