BBC WorldService logged for 59 minutes from 0500 UTC. 22.27 dB max. SNR and 48.26 % decoded audio.

Perhaps the Solar flare did influence the reception yesterday, perhaps it didn't. The reception was very much the same again here this morning.

OT: Ionograms

Neil, which Ionogram are you looking at? Mostly I use Juliusruh as it is sort of halfway between my location and central Europe.

Ionosonde

Hi Terje, I use the ionosonde which is located at the Rutherford Appleton Laboratory. It is at a small village called Chilton (nearest town Didcot), which is about 35 km from my location, so should give me a good indication of my ionospheric conditions.

Thanks Neil,

I keep a list of different Ionogram sites. Ionograms are quite helpful sometimes. The reception of BBC this morning was not particularly good. Only 21.5% decoded audio.
