Thunder and lightning - NOT amateur radio

For the last 20 minutes we have had thunder and lightning here. According to the time between the lightning and thunder it was about 1 mile away. My radios and PC will remain disconnected. Looking at the map linked below it seems to be tracking NW the worst may now have passed. It remains very dark outside and we can still hear thunder.

UPDATE 1830z:  Although the storm risk seems to have passed today, more storms are possible tomorrow, so I may leave things disconnected. 

Innocent until proved guilty? - NOT amateur radio

A recent case has arisen in which a man found guilty of a serious crime has professed his innocence to a number further charges. Mud sticks and innocent people get tarred even when they are later proved innocent.

Personally, I think no-one should be named until they are proved guilty of any crime. The law is an arse if innocent people are found guilty by the mob. I can think of several examples where lives have been ruined, wrongly. If guilty, the courts will find this and justice will be done.

Lightning maps

See http://www.lightningmaps.org/realtime?lang=en .

I find these maps very useful as they give advanced warnings of approaching storms. Even when storms are some way away you can get surges that can damage equipment. With approaching storms I tend to disconnect radios and PCs and unplug antennas and mains connectors.

Years ago, a friend at work got struck (his house) and I have always been a bit wary since. Thunder and lightning can be very nasty.

Sunspots and 10m - Thurs April 14th 2016

Solar flux is 112 today and the sunspot number 41 (K=3). The forecast for 10m propagation is yet again "poor".  It is unlikely I'll be on the band today as there is a risk of thunder and the band will be closed for DX later. I may go straight to 630m after dark.

472kHz last night

PA0RDT (243km) was best DX on TX on 472kHz WSPR last night. In all, three different stations spotted my 5mW ERP. It was a disappointing night on the band.

I have now gone QRT on all bands as there is thunder forecast. I may resume operations later when the threat is no longer with us.

CDARC 2m FM Net

This evening at 1900z I came on the 145.550MHz Cambridge Club net. I had a long chat with M0SND (Waterbeach) who gave me a 59+50dB report despite me running QRP to an omni-vertical. Alex is 92 years old  and was a regular on our Monday 2m net. It was good to talk with him again.

At one time (early 1970s) I was on the committee of the Cambridge club. It is some years since I last went to the club. I am not keen on driving in the dark these days.

See www.cdarc.co.uk  .

Return to 472kHz WSPR

We have been out most of the day at Felixstowe Ferry for a walk next to the sea and a lunch of fish (fresh) and chips at the old fashioned cafe that has been there since 1958.

I have been on 472kHz (630m) WSPR since 1936z. Only spots by M0LMH (223km) so far of my 5mW ERP, but the evening and night are young.

UPDATE 2100z:   LA8AV (1035km) is the best DX on RX so far tonight on 472kHz WSPR.

Steve G1KQH - NOT amateur radio

Steve did look for deals on eBay yesterday and found the Bluetooth smart watch for a little over £4. See yesterday's post. I do not understand how they do it for the price and ship it half way around the world.

Steve also sent me a link in which you can check MOT history.

40m WSPR overnight

No great DX last night with only European spots given and received overnight. On previous 40m WSPR outings I have been copied in North and South America and Australia. No such luck last night!

Sunspots and 10m - Wed April 13th 2016

Solar flux is 113 today. Sunspot number is 34 (K=4) and the forecast for 10m propagation is again "poor".

As there is a chance of thunder, I am not currently active on any band at present. I shall review the situation later.
