OFCOM to release new "airwaves" (sic)

Gosh! 700MHz and 3.6GHz spectrum to be auctioned. OFCOM provides such a useful service.

Manned lunar missions - NOT amateur radio

It seems amazing to me that the first manned landing on the moon was in 1969 when I was still at university! Looking back, it all seemed so routine, whereas we had no real idea how dangerous these missions were. Just think of the computing "power" we had back then. The fact that no-one has been back since the early 1970s speaks volumes.

I well remember that photo of earthrise taken by the crew of Apollo 8 in December 1968. It was stunning. Apollo 8 was the first manned trip around the moon. It did not land.

When will the next manned mission to the moon be and when will man go to Mars?

2m FT8 RX

Yet again, I am monitoring 2m FT8. Already 7 stations in 3 countries spotted with best DX DF6PW (633km). This sort of DX is spotted every day on 2m with this mode.

UPDATE 1219z: Now 12 stations in 4 countries spotted today so far on 2m FT8 RX.

Sunspots - Tuesday December 18th 2018

Solar flux is 70 and the sunspot number zero. A=6 and K=1.

Simple minds! - NOT amateur radio

A few weeks ago we bought a new clock for the hall. Every hour (not 2200-0500z) it plays a different birdsong briefly on the hour. Every time in makes a noise we laugh.

Simple things please simple minds!

Candlelit Carols - NOT amateur radio

Every Christmas our village church holds a carol service by candlelight. It is magical and usually packed. Whether a Christian or not, this sort of service marks the real start of Christmas.

Personally, I am unsure what I believe. The only thing I know is how little I know! Life/death/the universe are all mysteries. When we die I have no idea what, if anything, of "me" survives. Maybe my brain has evolved to the complex organ it is over billions of years. Perhaps we really just do return to dust. All I know is how little I understand. If anyone claims they know all the answers they are deluded. Maybe all religions are just attempts at answering "ultimate" questions.

Sunspots - Monday December 17th 2018

Solar flux is 70 and the sunspot number 0. A=2 and K=2.

2m FT8

Overnight, I remained on 2m FT8 RX. Even when the contest was over, there was still plenty of DX around. Most people appear have moved to WSJT-X V2.0 now.

Best DX at the moment is GW6TEO (371km) in west Wales.

UPDATE 1124z:  10 different stations in 4 countries spotted so far today on 2m FT8 RX with best DX DF6PW (633km).

UPDATE 1634z: Now 30 stations in 6 countries spotted today on 2m FT8 RX.

UPDATE 1832z: Now 36 stations in 7 countries spotted today on 2m FT8 RX.

UPDATE 1902z: These are the stations spotted today on the 2m big-wheel omni antenna on 2m FT8 RX.

VLF earth-mode transmitter

Before my 2013 stroke I enjoyed experimenting with VLF. Quite a few European amateurs were copied. This required special software, very narrow bandwidths and very long integration time. Casual listening does not work with very weak amateur signals!

In TX I was restricted, but did some useful experiments with VLF earth-mode. Best DX with 5W QRSS was 6km.
