Odd clouds - NOT amateur radio

These odd clouds appeared as a FaceBook memory from 2019. I was wondering if they were fribratus clouds? Let me know what you think. I cannot remember what the day was like.

This was "our" windmill seen out the window.

Next SAQ (17.2kHz CW) test transmission

Next Sunday, this historic alternator TX is transmitting for Alexanderson Day on July 4th. I have a QSL card somewhere from them for a transmission many years ago. This is a good chance to test your VLF system.

10m FT8 in the last day with the loop

Compared with a half decent outside 10m antenna I know my loop (50cm across, indoors) is at least 1 S point down. This means stations others copy, I miss. 

Nonetheless, 197 spots in the last day is not bad. These were in Europe, Africa and South America. In the next few weeks with help, I hope to get a decent outside antenna up for 10m.

10m FT8 RX

 

Stations spotted

At 0653z, my 10m FT8 RX was turned on with the tiny indoor loop. So far (at 0700z) no spots.

UPDATE 0710z:   Just M0BPQ (74km) spotted.

UPDATE 1020z:   140 stations spotted on RX. Mostly Es. The map shows the stations spotted on RX at 0950z.

UPDATE 1336z:   247 stations spotted on 10m FT8 RX.

UPDATE 2120z: 336 stations spotted today on 10m FT8 RX. QRT shortly.

Replacing the slats - NOT amateur radio

The 200 year old windmill next door is being repainted. Today, they've started to put the slats back on the sails. 

Backscatter compendium

The microwave bands are an area of amateur radio that I have never got seriously interested in, although we can only do so much I guess. Quite a few people are doing ATV at 5.6GHz using low cost modules.

Years ago I bought the "Backscatter compendium". This is now available free to download.

30THz tests

 Working on optical frequencies at 481THz seems easier!

Grandchildren - NOT amateur radio

We are lucky to see quite a lot of some of the grandchildren. 

Here two of them are with their granny. 

eBay fan - NOT amateur radio

Talking about eBay made me think about a fan my wife bought off eBay many years ago. See photo of the fan.
