SSN’s still very low

Alex | October 7, 2008

The suns having a lazy autumn. or spring depending on you hemisphere. The numbers through on the ARRL propagation bulletin make for a fairly low reading with what is reported to be a a bit of a pattern where a sunspot appears for a few days then is quick to disappear. The chart below shows the decline and makes for interesting reading / viewing. As expected there are a number of theories but as yet I’m not sure what it tells us.

Propagation?

Alex | July 30, 2008

I can confirm that there is little or no propagation going on at my QTH. Just look at the current graphs. There maybe some sporadic E floating about but I can say for certain that when I turn on my HF rig, there’s nothing at all to be heard.

Lucky I’m traveling further south for a few days soon so I can at least hopefully have a few QSO’s whilst qrp in the centre of England. Theres always a chance that somewhere in the UK there’ll be a lift.

Sometimes these lows can be low if you get what I mean :-(

Google earth and the ionosphere

Alex | June 3, 2008

You may have noticed that there are more and more applications coming to light that make use of google earth. the first that I came across was logging and I was pretty impressed with what I saw, next was dx clusters and that too sent me sky high with what this integration can do for us mere mortals.the list was growing and growing and nicely done it was too.

Now the ARRL has reported that there is a virtual ionosphere that can be superimposed onto your very own google earth.

I upgraded my installation through the faithful synaptic and I am really impressed with what you get. the work is done by CAPS (Communication Alert and Prediction System) and the details are here. A screenshot of it displaying the foF2 fro today on my machine is below.
