USA call areas

Maybe I am just too old, but I remember when W7 or W6 was on the west coast and W4 was on the east coast. These days it could be anywhere! In many ways we have gone backwards not forwards.

Sinclair portable

This dates from the 1960s I think and was a medium wave AM radio in kit form.

10m 500mW WSPR (Friday)

 When on 6m FT8 I can go on 10m WSPR with my beacon.

UPDATE 1415z:  11 spots mainly from the USA and Canada.

6m 5W FT8 (Friday)

I have now gone QRT on 10m FT8 and am now on 6m 5W FT8.

UPDATE 1540z:  33 stations have spotted me.

Wicken Fen

This is either the oldest, or nearly the oldest, National Trust reserve in England. 

It is about 6km from us.  It has a rich diversity of wildlife and they try to maintain the water levels so it is as the fens used to be before it became rich lands of agriculture. 

I have just been lent a book all about it. It is hard reading!

10m 4W FT8 (Friday)

For a change, I am on 4W 10m FT8 today. My gear was turned at breakfast time.

UPDATE 1222z:  Spotted by 202 stations with the best ZS2PA (9870km) in South Africa. See map.

Sunspots - Friday October 10th

Solar  flux is 122 and the SSN 87. A=5 and K=2.

10m 500mW WSPR (Thursday)

My beacon was turned on at about 1150z. The USA is starting to come through.

UPDATE 2142z:   27 stations are spotting me, including most of these in the USA or Canada. Best DX was a spot by ZD7GB (7611km). Now QRT.

6m 5W FT8 (Thursday)

My 5W 6m FT8 was turned on at about 1150z.

UPDATE 2135z:  22 spots with the furthest SM4VBO (1310km). Now QRT.

Is Russia in deep trouble?

Apparently OPEC+ has agreed to increase production still further, which is likely to result in a further fall in oil price per barrel. Also Ukraine drone strikes have been targeted at Russian oil processing leading to shortages at pumps. As Russia depends heavily on oil exports, this could really hurt.

Thursday plans

 Later, I expect to continue with 6m 5W FT8 and 500mW 10m WSPR.

Reflective sun

This was the setting sun reflected in the window of our local museum seen from our window.  The hedge is ours.

Sunspots - Thursday October 9th

 Solar flux is 120 and the SSN 109. A=11 and K=0.

6m and 10m FT8 or WSPR beaconing

To just beacon on 6m or 10m FT8 is easier than a full QSO.  Just beaconing just requires a very brief opening, whereas a full QSO takes several minutes.  In this respect FT4 might be better.

WSPR takes far longer which is one reason WSPR can be harder. Another is activity: I get the impression there are far more people on FT8 than WSPR. Also, even though WSPR can be decoded at much lower levels, local noise may bury weak signals, so unless there is a low local noise floor some openings may just be missed.

My overall conclusion is to stick with 6m FT8.

VLF up-converter

Yesterday I had an email saying the link to this page on my website was not working. It turned out this link was to my old site anyway, so I have corrected the link to point to the newer site.

See https://sites.google.com/view/g3xbm4/home/vlf/vlf-converter .

A reminder that this extremely unlikely to work with amateur VLF signals which need very narrow bandwidths and very accurate frequency. It is, however, suitable for general listening "down there".

Village cottage

Our village is a mixture of some old houses and new ones. This one is old, but I do not know when it was built. 

I guess it is 200m from our home?

8m operation

As I was not prepared to pay to do research I did not renew my 8m TX permit when it expired this summer. 

I was very disappointed by the very negative attitude of several PTTs even to very limited access to the band around solar maximum. I am told that it is still being used by some.  I really wish them well.

Instead, I have concentrated on 5W 6m FT8 to the V2000 vertical omni antenna.  This autumn my QRP has been spotted by 2 stations in Brazil on 6m.

10m 500mW WSPR (Wednesday)

 My beacon was turned on at about 0820z.

UPDATE 1835z:  8 stations have spotted me today with the furthest KY4UI (6834km) in Georgia USA.

UPDATE 1925z:  When I went QRT the furthest spot was again by DP0GVN (13685km) in Antarctica. In the last few weeks my 500mW has reached the German research base down there several times.

Flatlights

Before my 2013 stroke got in the way, I was hoping to get much further over the horizon with 481THz red light. 

To that end I purchased some very bright LEDs called Flatlights. These take (I am told) 8A from the power supply! The photo show the Flatlight that, sadly, did not get used.

In my earlier tests at just under 9km over the horizon there was no sign at all of a red light in the sky, yet the signal from my beacon was very clear on the PC.  

Even with that, far further would have been possible. As the sky was cloudless, I assume this was clear air scattering off dust particles. I did not try cloud-bounce where signals are reflected off the base of clouds. 

6m 5W FT8 (Wednesday)

My gear was turned on at about  0820z.

UPDATE 1939z: Spotted by 40 stations. See map.
