Dyson hand driers - NOT amateur radio

In recent days, these have had a bad press. These are the blade driers found in loos. The bad press claims they circulate germs in the air far more than paper towels. I am surprised by this as I thought most air was contained and they are very efficient and fast.

Staying on 5MHz WSPR

In the end, the "London" grandchildren have only just left for home, so I have decided it is too late in the day to QSY to 10m. Instead, I'll remain on 5MHz (60m) WSPR until tomorrow, hoping for some DX tonight.

5MHz WSPR overnight

Well, I stayed on 5MHz (60m) WSPR overnight. Best DX on TX was KK1D (5409km). In all, 40 different stations in 12 countries have copied me on 5MHz WSPR.  I think others are copying me better than I am copying them as my noise floor is quite high here. So far I have heard just 7 unique stations, all in the UK.  If I am going to use 5MHz (60m) in future years I need to reduce my noise floor on RX.

Later today, I shall probably go back on 10m WSPR.
 
We have our "London" grandchildren staying here this weekend with their mum and dad. They take priority.

Sunspots and 10m - Sun April 24th 2016

Solar flux is 79 and sunspot number just 11 (K=2). The forecast for 10m remains "poor".

5MHz WSPR overnight

WSPRnet sprang back to life this afternoon (I think). It disappeared sometime overnight after 0250z I believe. This eventually allowed me to see the best 5MHz DX last night on WSPR TX. This turned out to be a spot from AB4DF (6436km). There may have been others, but WSPRnet fell over, so I shall never know. I hope to be on 5MHz overnight, so let us hope WSPRnet works! My antenna is very poor and very low for 5MHz. I am amazed how far I got last night with 2W and this low, inefficient antenna.

UPDATE 2135z:  37 unique stations have spotted my 5MHz WSPR in just over a day. Probably more as WSPRnet was not working for much of the time. 5MHz is proving to be a very useful band.

New portable SDR transceiver

Amateur Radio Weekly reports on a new portable SDR transceiver due out in August this year. Price is expected to be less than $500.

Chernobyl pollution map - NOT amateur radio

A very interesting map showing the extent of radio active pollution in Europe after the Chernobyl nuclear accident in the 1980s.

5MHz WSPR - am I wasting my time?

With WSPRnet still not working I have no idea if last night's efforts were worthwhile or not on 5MHz. The chances are that no spots are/were reaching WSPRnet, so the last 12 hours or so were probably all in vain. If this continues I shall be forced to abandon WSPR, which would be a great shame as we enter the Es season, which benefits the higher HF bands, 6m, 4m and 2m.

Obama in the UK - NOT amateur radio

In the UK referendum I am likely to vote "IN" to remain in the EU but I get saddened by all the negativity and "spin" on both sides in this debate. The intervention by the current US president Obama does little good. We have not had a trade deal with the US before and who is likely to benefit? Well, the USA of course. Mr Obama, your intervention, although possibly well meant, is probably going to encourage people to vote "OUT".  It is fine to have an opinion (like I am amazed by the support in the USA for Trump) but if you were in the EU you would not want the centralism in Brussels.

The EU needs to change and the UK is better in there shaping it in my view. Your intervention is likely to backfire Mr Obama and is not helpful I am afraid.
