Sporadic-E (Es)

So far, this has been a disappointing Es season. Things hopefully will change, but 8m has been very disappointing so far. By now, I was hoping for openings most days. 

UPDATE 1732z:  At the moment there seems to be a good Es opening in Eastern Europe. See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ for G7IZU's excellent website.

Distant Konik ponies - NOT amateur radio

We saw these in the distance on our a walk to Wicken Fen at the weekend. They are used to keep the grass short, naturally.

Cow parsley - NOT amateur radio


This field in Burwell is full of cow parsley at those time of year. 

Eddystone EC10 receivers

From time to time these still appear on auction sits like eBay, commanding ridiculous prices. As a young person these were highly coveted. In reality they were unbelievably poor. These days a low cost SDR dongle offers far superior performance for far less than the 1968 new price!

Keeping an eye on Es in Europe

Following Hugh's (HC02) suggestion, I am now looking at this map of 8m Es in Europe.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/8m-40mhz-spot-band/

On the same site is this map showing live Es data for other bands. I get the feeling 8m Es could be promising later.

10m 500mW WSPR TX (Tuesday)

My beacon was turned on at about 0820z. 

UPDATE 0924z:   So far just local spots.

UPDATE 1326z:  3 unique spots so far with the furthermost being deep in the Indian Ocean.
UPDATE 1903z: 
 7 unique spots today. I do not think there was any Es today.

UPDATE 2040z:  QRT.

Royal Gloucester Bell - NOT amateur radio

Yesterday we went to the exhibition at Norwich Castle Museum of the Royal Gloucester ship. This is the ship's bell. 

8m QRP FT8 (Tuesday)

As I was not on the air yesterday, I intend to go on 8m FT8 later. As the 10m antenna is available I will be on 10m WSPR TX with 500mW too. 

UPDATE 0927z:  Gear turned on about 0820z. No spots on RX or TX.

UPDATE 2044z:   QRT. It is now some days since I have had any spots on 8m FT8. Es seems to have been poor so far this season.

Sunspots - Tuesday May 16th 2023

Solar flux is 135 and the SSN 103. A=6 and K=1.  Numbers look back to normal.
