VLF Loading Coil
Joe VO1NA sent me a nice photo of his VLF loading coil (8.277kHz), which I have copied here. For those carrying out radiated tests at VLF you have to be able to wind big coils! Sadly, the top coil arced in testing and had to be rewound.
10m JT65 today
At the moment I am on 10m JT65. There have been no spots so far. No Europeans by Es, no UK spots - nothing! I shall stick with it but without Es it could be a quiet day, HI.
UPDATE 1026z: Still nothing RX or TX on 10m JT65 here.

End of main Es season?
It is now early September, which the UK Met Office calls the start of autumn. Nights are starting to draw in and the days are shorter. With another day with no signs here of Es on 6m and 10m, I think we are definitely at the end of the Es season in the Northern Hemisphere. Yes there will still be some Es but nothing like the scale in the summer. Today, only UK spots on 10m WSPR and 6m JT65. Let us hope the F2 this autumn is not too bad on 10m. I think tomorrow I shall switch to 10m JT65.
JT65 - early success on 6m
Although there is no Es evident here yet, several UK stations have spotted me, and been spotted' on 6m JT65. Best DX spot is G1IDZ (182km).
UPDATE 0938z: On 10m WSPR nothing since M0DMC (15km) who was consistently spotting me until early this morning. I have checked that the 10m WSPR and 6m JT65 are synced to internet time.

Sunspots and 10m - Thursday Sept 1st 2016
It is hard to believe it is already September! Solar flux is 95 and the sunspot number 91 which is much higher than we have seen lately. K=4. The forecast for 10m F2 propagation remains "poor".

QST - thank you Rupert
Rupert G4XRV very kindly sent me a copy of September QST. Rupert reads my blog from time to time and saw that I had not seen the magazine in which my recent article appeared. This was very kind and much appreciated. Thank you Rupert.

Counting Sheep? - NOT amateur radio
This was one of my grandsons at our local farm shop and cafe. I wonder if he was counting sheep trying to get to sleep? He is eight, nearly nine.
Fun at the fair - NOT amateur radio
On Monday we went to the Fenland Country Fair.
Our grandchildren (5 and 8 years old) went on the helter-skelter twice. For the younger one, it was her first time.
They go home tomorrow.

Operating today
I decided to go on 10m WSPR (500mW) and 6m JT65 (1W ERP) today. 10m has been very quiet here but I had a number of UK spots of my QRP JT65 signal on 6m. My best report on 6m JT65 was from G0VUH (157km). So far, I have seen no evidence of Es here yet on either band.
Sunspots and 10m - Wednesday August 31st 2016
Solar flux is 99 and the sunspot number 64 today. K=2. The forecast for 10m F2 propagation remains "poor".
No Internet
Yesterday, we had no internet, so no posts were possible. I am very sorry. It is back today, so I hope to post more later, if the internet carries on working!

10m JT65 - South America yet again
PU2TWU (9572km) spotted me a little while ago on 10m JT65. I spotted EA8 (Canaries) about an hour ago. The latter could have been Es or F2. This is in the same direction as the South American station who spotted me. I am amazed how regularly I get spotted on 10m JT65 in South America with just 2W. My antenna is low and nothing special, so I hope my results encourage others to try 10m QRP.
Fenland Country Fair - NOT amateur radio
We have grandchildren here this week. Today, we went to the Fenland Country Fair at nearby Stow-cum-Quy, where we have been for several years.
Sadly, the toy Land Rovers (electric cars) were not there. Our grandson enjoys driving these.
They went on lots of rides and enjoyed their ice creams!

UPDATE 1930z: LU2FGL (11167km) in FF97 square was the best DX spotted on 10m JT65 this evening at 1902z.
UPDATE 2036z: With 4 different South Americans spotted on 10m JT65 (the latest was Paraguay), this is the best DX on the band for some time. I am still curious about the Es link as there was good Es in the right direction.

Return to 10m JT65
A short while ago, I QSYed back to 10m JT65 from 6m. There is more chance of DX on 10m especially this afternoon and evening.
UPDATE 1246z: We had a little rain about 30 minutes ago, but the weather looks good for most of the week ahead. We have grandchildren here, which is good.
UPDATE 1304z: Since returning to 10m I have not been spotted, or spotted, anyone yet!
UPDATE 1500z: All the 10m JT65 spots were Es at breakfast time, with nothing since, as yet.

Our garden - NOT amateur radio
Our garden is better in spring when the blossom is freshly out.
Our grass is going brown in places as we had quite a decent August after a poor start to summer. It always recovers after some rain.
The picture shows me next to one of our rowan trees in our garden with the windmill in the background. Richard G3TFX took the photo. He thinks I should string a long wire to the top of the mill! Of course the top and sails turn to face the wind. It moves several times in a week. Currently the sails are facing west. In this picture they are facing south.

5MHz
Southgate News reports that the SARL is trying to get a 100kHz slot at 5MHz. I think this is wise. A larger contiguous band would be so much more useful than the 15kHz worldwide allocation that was granted at WRC 2015. I hope CEPT countries try for a 100kHz wide 5MHz band. It could happen that quite a few countries allocate a 100kHz wide band on a secondary basis to the amateur service. In the coming quiet solar years this could become an important band.

New rig - not at the moment
I was going to invest in an IC7300, but, for the moment, I have decided not to bother. The FT817 serves me well and I am not that interested in running more power. If the price drops a lot I might think again. The FT817 certainly serves my needs on 10m and 6m JT65 even on the middle power setting. I also have a transverter for 630m (see my design in the latest QST). I also have a stand-alone 500mW WSPR beacon for 10m.
Es - don't give up!
With another day with respectable Es on both 10m and 6m, the Es season is not yet over. OK there are probably fewer openings than a few months ago, but there are openings and when these bands are good for Es they are good. I recommend WSPR or JT65 as a way of detecting these openings. I find JT65 better on 6m as the levels of activity are greater. WSPR is theoretically able to work with even weaker signals. JT9-1 works on 10m and occupies far less bandwidth than JT65, which is already quite narrow and much better than CW.
UPDATE 1155z: Quite a few Es spots from Europe on 6m JT65. I'll probably switch to 10m JT65 shortly.
UPDATE 1825z: 10m Es has returned. Just been spotted in Sweden.

Early Es on 10m and 6m
I stayed on 10m JT65 overnight but switched to 6m JT65 around 0800z. There has been early Es on both bands, which is encouraging.

Chile - best DX tonight on 10m JT65
https://pskreporter.info/pskmap.html |
UPDATE 2145z: Lots of European Es now. This was very late but it is as good as any day this season now.
Storm risk gone - 6m JT65 in the morning (probably)
The storm risk has moved away over the Wash and into the North Sea. There are still storms in north Norfolk but they are moving away NE. So, I shall remain on 10m JT65 this evening. I could stay on overnight, but I shall probably go QRT later and come back tomorrow breakfast time on 6m JT65. There are fewer DX opportunities on 6m than 10m but more Gs on 6m than 10m JT65.

10m - an amazing band!
OK, so the sun is less active now but 10m is still filled with surprises! After a fairly average day with a few Es spots on JT65 from Scandinavia I get spotted in Southern Brazil! Now the band is open to Latvia, Sweden, Finland and Belarus to name a few, presumably by Es.

Football - NOT amateur radio
My old "local" team, Plymouth Argyle, had a dreadful start to the football season but have now won the last 3 games and are currently in the play-off places. Mind you, it is very early days. My current "local" team, Cambridge United, is currently at the very bottom of the league. Unless they buck up they could lose their league place at the end of the season.
Brazil (again) on 10m JT65
Another theory bites the dust....
PU2POP (9582km) has copied my QRP 10m JT65 in the last 20 minutes. As there was very little 10m Es here, this suggests F layer only. I was not expecting to reach South America today, although I was hopeful.
UPDATE 1545z: 10m Es now to Sweden and Finland.
UPDATE 1608z: The storms seem to have missed us, passing over Peterborough and Northampton. Mind you, I am still watching the maps with concern as I think there could be further risks later. New Es from Scandinavia in the last few minutes.

Back on air - 10m JT65
Whilst keeping one eye on the storm map, I have returned to JT65, this time on 10m, hoping to catch some DX to South America. Judging by the lack of Es in the right direction, I'd be quite surprised if my QRP 10m JT65 got that far today.
At the moment, the storms are giving us a miss, although things will get disconnected as soon as the risk increases. See http://www.lightningmaps.org/?lang=en .
UPDATE 1505z: A few minutes ago I was spotted on 10m JT65 by SM5EPO (1347km). Es I assume.

Gone QRT
There are thunderstorms moving up the country. At the moment these are tracking west of Cambridge but I have disconnected everything for now. I'll re-assess the risks later.
Before closing down I spotted 4 different UK stations and was spotted by 2 UK stations on 6m JT65. Up to now, I have seen no 6m Es today. When I reconnect things I'll probably come back on 10m JT65.
UPDATE 1240z: It looks like the storms are passing well west of us and we will miss them. It is just starting to spit the odd rain spot. I'll give it an hour then re-assess things.
UPDATE 1252z: Presently, the storm is over March up in the Fens and moving away and nowhere near us.
UPDATE 1402z: We seem to have missed this one. See http://www.convectiveweather.co.uk/forecast.php?date=2016-08-27 .
UPDATE 1408z: Instead of amateur radio we went picking blackberries, plums, apples and runner beans in the orchard next door. The owner is away and said, "help yourselves".

Solar flux is 82 today. Sunspot number is 44. K=1. Yet again the forecast for 10m F2 propagation remains "poor".
6m and 10m JT65 today
As most 10m DX seems to be late evening and afternoon, I decided to go on 6m at present. I was briefly on 10m JT65 first thing. Already I have been spotted bt a couple of UK stations on 6m and I have spotted some Gs too including G0GGG (241km).
There is an outside chance of storms after lunch, so I am keeping a watching brief.

Amateur Satellites
Next year, if all goes to plan, we may have an amateur satellite in a geosynchronous orbit permitting long distance propagation at almost any time day or night. As the solar activity declines, this could be a lifeline. I have little experience of amateur satellites and only had a single QSO via a low orbit satellite. Geosynchronous should mean lower Doppler and hours of operation whereas low orbit satellites go out of range within 20 minutes. Years ago I recall the excitement of hearing US and Canadians on Oscar 6 and 7 on 2m. Being on microwave bands should mean much greater transponder bandwidths. Also, dishes can be fixed as the satellite will always be in the same place in the sky like a TV satellite.

Brazil on 10m JT65 today
Well my theory about Es and F layer over the equator being needed to reach Brazil on 10m at this time of year seems to be holding up, after a fashion. PY2IQ (9585km) in Sao Paulo was copied at 1916z. There was some Es today, although not much. As the autumn "kicks in" we may see more South Americans by F2.
