I can see it in Swansea IO81CR

Using SDR-IQ, SDR-Radio software, 100m loop ant roughly E-W.

clearly visible, with hints of what appears to be a 7-second flutter 
together with some much slower fading.

It's there now and I've just restarted the grabber.
Only just over the noise here, but expect it to pick up later on.

Hello Paul-Henrik!

I can see no sign of the signal yet, at 16:45UTC! (Just SM6BGP testing)

I'm going to try making a passive tuned multi-turn loop tonight and see if I
can use it to get a bearing. I might be able to use this loop with an FT817
and if necessary a netbook showing a waterfall display to see a null in the
noise, even if I can't tell by ear.

I have a feeling it's not too close to me either!

Cheers,


John
