HF propagation

In the last few days (until today) I had given up on 8m. Today, I am back on the band and have been spotted by 4 stations including 2 in the Caribbean. F2 conditions appear to be quite good still. It is worth keeping an eye on propagation including the MUF.

Realtime HF Band Conditions

Southgate News reports on a real-time HF band conditions website. When I looked 10m was not even shown, encouraging the (often false) assumption that this band is a total waste of time for DX. OK, 10m is harder work now, but if no-one is there it will appear dead when in fact DX contacts can be made!

HF conditions - use the higher bands

For about a day, I went on 20m JT65. It was too easy, with spots all across Europe and the USA even with 2W and a poor antenna on 20m.

HF conditions are not as good as at the sunspot peak, but they are often better than people realise: of late the sunspot number has been in the 40s or higher and the solar flux has been above 80. Even 10m is capable of supporting DX, although few realise as they leave the higher bands and go for easy pickings on 20m or lower.

My strong recommendation is try digital modes on 10m. OK, it is not as easy as a few years ago, but DX still pops up. 10m remains "open" far more often than is realised, even in the quiet solar years What is needed is activity!

Amateur radio is about self training and exploring the boundaries. If you just want to speak across the planet you can video conference for free with Skype on the internet. 10m with digital modes and QRP is much more fun.

Second peak for cycle 24?

It looks more and more likely that cycle 24 is going to have a second peak with a greater magnitude than that of the first peak of Feb 2012. Today the sunspot count is 150. It will take several months before the smoothed sunspot number is known, but the indicators are good.

Recent excellent conditions on 10m are further evidence of good times. Since home from hospital (Jan 3rd) 10m has been open to N.America every afternoon that I have listened.

As the slope down to the minimum is more gradual than the ascent to the peak(s), we can expect decent HF conditions for a few years to come.

The new peak is not great and we may we be heading to a Maunder Minimum with very little sunspot activity for perhaps 40-50 years. Enjoy these HF conditions while you can  because we may not see them again in our lifetimes.

UPDATE 1300z:  My first report from the USA (running 2W WSPR) was as early as 1244z, indicating a VERY early 10m stateside opening today at my very low power level.. Conditions remain excellent on 10m.  7088km, not bad.
