Autumn

And so is the vernal equinox. Tomorrow (23rd) is apparently the date when things start to get a bit more useful on the HF bands. During this last solar cycle I’ve developed an interest in propagation over and above what I would have as a normal ham. Still it seems that this cycle brings with it promises of propagation riches that don’t seem to come to light. I’m not holding out for a massive change but on reflection something like the spring would be greatly appreciated. Can you here me sun ;-)

End of the summer lull?

Some activity finally rolling in.

Theres hope for a few QSO’s to South America but only if I stay up very late. Not much chance of that at the moment though. A few more weeks should do the trick nicely!

Where’s all the activity gone?

All I seem to get at the moment is noise!

having had a pretty poor Es season compared to last year I have switched back to HF. This hasn’t really worked either…..There must be some radio gremlins floating about as I’ve hardly even heard a European station for weeks let alone someone from further afield. All I’m getting is a load of old noise.

Good for the XYL as its made me fit the new Freesat cabling ( I don’t do Sky) for our PVR. Tidy up the garden and other uninteresting home type tasks. I even managed to get out and do a 10 mile time trial on my bike last Tuesday. Another first.

Its amazing what else you end up doing when the bands are dead… 8-)

Am I dreaming?

Smoothed Sun Spot Numbers

W1AW reports through the regular bulletins that the sun spot numbers have changed a bit over the last few months to give an extended low. Something that is all too familiar if you try and listen out for DX at the moment.

Below is a graph of the smoothed numbers that are taken from the recent published numbers. I’ve added a polynomial trend line to show what the smoothed smoothed sun spot numbers look like.
