Optical kit

One of my Facebook memories today is of testing my 481THz optical kit in the garden of the old QTH. In those days I was fit and well. These days, field work has proved impossible although I still hope to restart one day. The photo is here as a reminder (to me!).  And, no, I was not looking at that attractive girl up the street!

All the optical kit was homemade and easy to assemble and test in the back of the garage with very basic test gear. Even the software used was free. Over the horizon testing with optical kit was challenging and great fun. Results amazed me.

10m antenna for the Es season

As we are about to enter the Es (sporadic-E) season in the northern hemisphere, quite a few people will be looking for a quick, simple, effective and low cost antenna for 10m. May I introduce the Homebase-10 antenna?

By scaling the size, it will also work on 6m and 4m too. At the old QTH it was used for many years. You'll be hard pressed to find something as simple as effective. It appeared in Practical Wireless some years ago.

This has been on this blog before, but many will not have seen it I guess.

Still no swallows - NOT amateur radio

By now, I have usually seen a swallow back from South Africa. They started arriving in Devon in March, but as yet, I have still not seen one! Numbers are dropping, but this is now very late.

10m FT8

After a very brief TX period, (no reports) I am again monitoring 10m FT8 RX, more in hope than expectation. But, if you do TX, I shall be there, HI.

UPDATE 0634z: Well there's a surprise! DB6LL (651km) in the Hamburg area has already been spotted on 10m FT8.

UPDATE 0816z: No further spots so far today.

UPDATE 1634z: 10m FT8  spots from Indonesia, Middle East, Africa and South America. A good 10m FT8 day without a doubt. Sunspot number? Zero!

Where I was born and brought up - NOT amateur radio

Until I went to university, I lived in the South Hams of Devon. This picture was taken 8 years ago, but it probably hasn't changed much in 1000 years. We know my ancestors owned a piece of land near here in 1428. I can trace the family tree right back to  about 1550 with no breaks. Our family has probably been hereabouts for thousands of years.  BTW, Thurlestone (this place) means "rock with a hole" so Thurlestone Rock has been there a long time!

Sunspots - Friday April 20th 2018

Solar flux is 70 today. Sunspot number remains zero. A=5 and K=1.

New Software

I just downloaded WSJT-X V1.9 rc3 and it seems to work fine with stations spotted from all over Europe on 40m FT8 RX in the last 15 minutes.

Kings - NOT amateur radio

As we are "local" we get cards which give us free entry into the Cambridge colleges. People come right across the world to see sights we take for granted. One photo shows Kings College Chapel and another the Wren Library and some punts.

Where we ate yesterday - NOT amateur radio

As mentioned before we visited Harleston and Diss yesterday. We ate lunch in Harleston in an antiques centre surrounded by old books and ephemera.
