First swallow (bird) seen in Devon - NOT amateur radio

A first swallow was reported in Devon yesterday. If this report is correct, this is the first seen this year. They usually start to arrive about now in Devon, but it is usually later up here in East Anglia.

VLF (8.97kHz) TX

8.97kHz 5W TX
Before my stroke in 2013 I did a fair bit of experimentation at VLF, successfully receiving quite a few European amateurs on VLF doing radiated tests. I did some "through-the-ground" utilities assisted earth-mode tests out to 6km using just a 5W transmitter. At some point I'd like to do more.

6m MSK144

This morning, I am again on 6m MSK144 RX. At the moment, the best DX is Switzerland.

UPDATE 1806z: GI4SNA (488km) brings my country total on 6m MSK144 to 17 now.

UPDATE 1834z: 7 stations in 5 countries received on 6m MSK144 RX today so far.

UKAC results

The results of the 2m and 70cm UKAC activity contests have been published and I notice I had points deducted for logging errors. These were me being careless - sometimes it is as if my brain runs at a slower rate than it once did and I fail to get everything written down. Later, I see there are missing data, but it is too late. I notice this with driving too - these days I drive slower as my reactions are not as fast.

Nonetheless, on both bands my scores were still respectable considering I use just 5W and a big-wheel omni on 2m and 5W and a 2m halo fed with lossy coax on 70cm! I enjoy these contests but I need to take more care with the logs in future. In the end, it is more about taking part than the actual scores, but I need to try harder. Getting accurate logs should be straightforward.

Performance of FT-817???
Very interesting well worthy of watching with a glass of beer..

Alien space travel? - NOT amateur radio

This is pure speculation and there may well be other explanations, but two Harvard scientists have speculated that alien lifeforms on distant planets may be travelling through the cosmos using powerful radio beams to power their sails.

Man has been searching for alien life for about 50 years. It is surprising that nothing has been found.

New cloud type - NOT amateur radio

Apparently, a new, rare cloud type has been officially acknowledged in a cloud atlas.

See http://www.bbc.co.uk/news/science-environment-39351843

Although I am not "into" clouds, I know some people are.

I do recall seeing lenticular clouds in the Yorkshire Dales some years ago.

Cowslips - NOT amateur radio

The first cowslips have appeared here and, by any measure, we are now officially in spring. The clocks go forward this coming weekend.

100 sand martins (birds) have been seen in Devon. These are migrants often seen returning about now. I remember my dad telling me when he first saw these over the golf course. He died in 1987 sadly. I miss him.
