10m WSPR
Whilst beaconing on 6m JT65 I am also TXing on 10m WSPR (500mW). Certainly later, conditions seem to be favoring northern Europe.
Kazakstan on 6m
UN3M (3555km) in Kazakhstan was copied on 6m JT65 early this morning. He was in locator LO61. My own JT65 6m signal (1W ERP) has been spotted across Europe again. JT65 does seem much more productive than WSPR on 6m.

Tim Peake - NOT amateur radio
Thankfully, Tim Peake who had spent 6 months on board the ISS, has returned safely to Earth. He has done much for the UK in space. We must not forget that space is still a hazardous environment. Getting back from space is still very hazardous.
Es season in full swing.
6m JT65 spots received in last 12 hours (1W ERP) |
UPDATE 1228z: Plenty of JT65 reports on 6m this morning at 1W ERP.

The Quiet Sun and 10m
We could be entering a very long period of very low solar activity, quite unlike anything in modern times. With noise levels much higher on the lower HF bands we may be forced to VHF and UHF satellites to work DX we have become used to. Summertime Es may soon be the only practical propagation mode for DX on 10m.
Don't forget we are dealing with averages and some days will allow N-S F2 DX still on 10m.
I am a great supporter of WSPR and very much hope WSPR users will continue on 10m even when the prospects are not good. I suspect 10m is "open" far more often than people think. A casual tune over the band may result in nobody being heard, so people move down the bands. With regular WSPR use, short openings on 10m would be "smoked out". Since only low power is needed for WSPR, this is an ideal mode for the "quiet sun" years.

Tim Peake - NOT amateur radio
After 6 months in orbit on the ISS, UK astronaut Tim Peake returns to Earth tomorrow, Sunday, in a Russian Soyuz space module. Re-entry is always hazardous, so we all wish him a safe trip back to Earth. Rather him than me!
It is funny how we are friends with Russia in so many ways, yet there is still distrust of them and them of us in the West. The sooner we all learn that the Cold War ended in 1989 the better for us all.

UPDATE 1845z: So far, 3 G stations have spotted my 6m 1W ERP JT65 transmissions. No Es spots of me this evening, although I have only been on TX for about 75 minutes.
UPDATE 1912z: I see I am now spotting a couple of 6m stations on JT65 in Ukraine. I hope stations over there spot me too.
UPDATE 1920z: UX4UA (2082km) in KO50el has spotted me, so it did not take long! I have also been spotted by a couple of stations in Finland. Clearly Es.
UPDATE 2005z: DK0SC (827km) has spotted my 10m 500mW WSPR. I am being spotted all over Europe on 6m JT65 with 1W.

10m WSPR
My 500mW 10m WSPR beacon is still running with spots from all over Europe again today. I like the mode as you can monitor WSPRnet in the lounge, and just pop in to the shack if there is a problem or to do a time re-sync.
But I agree that JT65 does seem a better mode on 6m. WSPR would be fine on 6m if there was more activity. Also, I suspect the one minute TX cycle in JT65 is better, even though the mode is less good at digging weak signals from the noise. Overall, JT65 seems right for 6m.
For JT65, I have to use my PC and FT817, so if I want to try the mode on 10m I have to stop TXing on 6m. With 10m WSPR I can use my stand-alone W5OLF WSPR beacon and be on 6m JT65 at the same time. The tiny W5OLF WSPR beacon does not need external audio or a PC.

More JT65 on 6m
I am still on JT65 on 6m this morning and have been spotted by lots of Gs as well as in Spain and France by Es. I call CQ and try to get into the shack to answer calls. I have a couple of questions.
My questions are:
1. I really want to just beacon sometimes. What should I send that will appear on PSKreporter? Calling CQ when I am really beaconing seems wrong.
2. Is there a convention to call CQ in even (or odd) minutes?
Although I am WSPRing on 10m at the same time, surprisingly I have not been spotted yet on 10m.
On 6m I am now beaconing and sending "B G3XBM JO02" at 1W ERP. This seems to be being reported to PSKreporter.

Gilbert and Sullivan - NOT amateur radio
This evening we went with friends to nearby Swaffham Bulbeck for a
Gilbert and Sullivan performance of "The Pirates of Penzance". Every
June a local barn is taken over to do a G+S production. It is part of
our year. The performance was excellent. It always is good. The cast is amateur but they always put on a first class show. At one point it rained heavily. Luckily the lights stayed on!
Sunspots and 10m - Wed June 15th 2016
Solar flux is 87 today and sunspot number 26 (K=3). 10m F2 propagation is forecast to remain "poor".
It is hard to believe we are approaching the summer solstice and the longest day. It seems 5 minutes since Christmas and the shortest day.

Still on 6m JT65
Today, I shall remain on JT65 on 6m, but continue with WSPR on 10m. A couple of G stations have already spotted my CQ on 6m in JT65, but no Es as yet. I have seen CQs from other G stations on 6m JT65.
UPDATE 1240z: On 6m JT65 I have spotted GU8BFO (374km) and OZ0TFW (829km) as well as several G stations.

Now active on 6m JT65
For the last hour or thereabouts I have been on 6m JT65 rather than WSPR. I am still just using the FT817 and the V2000 vertical omni fed with (lossy) RG58 coax.
Much to my surprise I am being spotted by G0LFF (146km) not far north of Brighton. At the moment I am calling CQ every 2 minutes, but I shall probably switch to RX only until after breakfast. There seems to be more activity on this mode than WSPR on 6m. It will be interesting to see what I spot, and who I can work, by Es tomorrow using this mode.
UPDATE 2050z: On 6m JT65 I have now switched to RX only until after breakfast tomorrow.

70cm UKAC contest - dreadful!
Well, although I only have 5W and a 2m omni antenna I usually have a go in this contest and give a few points out. Tonight was truly dreadful. I only worked 2 stations in the limited time I was active and only heard 3 stations in total. Conditions seemed very flat and activity low. Usually I can work far more stations at greater range.
Anne's old house - NOT amateur radio
We have a friend who has been to visit me most months. She lives in a
VERY old house. Today we walked to her house for tea and scones.
This roof, to the rear of her house, is a real problem in heavy rain as gallons and gallons of water flows off it, causing her cellar to flood. She has taken measures to minimise the problems but she is always nervous with heavy rain around.

QRT on 10m and 6m WSPR - thunderstorm risk
As there are storms moving this way, I decided to go QRT on both 10m and 6m WSPR and disconnect antennas and power plugs. The shack PC is also off and disconnected. Once the risk passes, I may reconnect. This could be some hours.
See www.lightningmaps.org to see where the storms are.

West Coast Canada to Africa on 6m
See http://www.amateurradio.com/ for a report by Steve VE7SL of his 6m exploits. This sounds like Es but on these very long paths I question the conventional theories of multi-hop Es. I wonder if this is some kind of chordal-hop Es? As I reported yesterday, my QRP 6m WSPR was spotted for the 3rd year running in Israel. It could be multi-hop but I have my doubts.
There is also the possibility of mesospheric noctilucent clouds being involved in some very long paths on 6m such as Europe to Japan. This 8000km + path seems to be there most summers. We have much still to learn.

Hornets in Kent - NOT amateur radio
One of our sons who lives near Canterbury, Kent, UK reports lots of hornet sightings this year. Maybe it is as they are quite near to France? Normally they are quite uncommon but he has seen lots this month alone. Of course it could be global warming and we are beginning to see less common insects more often? I have seen a few beetles and flies in the garden that I do not recognise. Perhaps they have always been around. I have asked my son to take some photos.

SAQ transmission
"Grimeton Radio Station was listed as a world heritage site because, its original equipment is an exceptionally well-preserved example of the development of communication technology. In fact, it is still in working order.
Grimeton (call sign SAQ) still transmits a message to the world twice a year: at the Alexanderson Day (Sunday at the end of June/beginning of July) and at Christmas Eve. The frequency is 17.2 kHz CW."
Next transmission is July 3rd 2016. I am lucky to have a QSL card for their VLF transmission some years ago.

Sunspots and 10m - Tues June 14th 2016
Solar flux is 89 today. Sunspot number is 27 (K=2) but 10m F2 propagation remains "poor".
Early start on 6m WSPR and 10m WSPR
OZ7IT (853km) was spotting my 1W ERP 6m WSPR at 0658z this morning. I assume this is Es, but early.
UPDATE 0900z: Steve VE7SL has suggested I monitor JT65 on 6m instead of WSPR as activity levels are higher. I am seriously considering this.
UPDATE 1002z: Lots of 10m WSPR spots from stations in Scandinavia this morning. Nothing more on 6m WSPR.

10m still open (Es)
It is 2106z and my 500mW 10m WSPR is still being copied around Europe. 10m WSPR has been good for Es all day. My "gut" feel is reports on 6m Es are generally much stronger than 10m, but there are too few WSPR stations on 6m.
UPDATE 2120z: IU1DZZ (973km) is still spotting me on 10m WSPR.
UPDATE 2138z: Now DK6UG (633km) is spotting me on 10m WSPR.

I am very sorry folks. About 30 minutes ago I cut my front lawn and now it is really raining very hard. According to the maps (see link) the thunder and lightning are heading this way. I shall stay on 10m and 6m WSPR for a little while, but I may well have to disconnect things soon.
UPDATE 1715z: Well, although it rained hard, the storms decided to miss us, so I am still active on 10m and 6m WSPR.

Israel (again) on 6m WSPR
For the third year running my 1W ERP has been spotted in Israel on 6m WSPR by 4X1RF (3519km). This is a long way on VHF. It has now happened at this QTH for the last 3 summers! It seems too strong and regular for multi-hop Es. To me, it seems more like some sort of chordal-hop Es.

PW QRP 2m contest - missed it again
Yet again I managed to miss the Practical Wireless 2m QRP contest yesterday. It would have been a good test of my simple station too. It is many years since I seriously entered this 2m contest. This was back in the days of AM I think and we operated portable with a big beam. These days, it would be from home with just my big-wheel omni.

At the moment there are thunderstorms in the UK, but these seem to be out to the west and in the Oxford area according to http://www.lightningmaps.org . I shall remain on 10m WSPR and 6m WSPR,but if they get nearer I shall go QRT.
They seem to be moving this way - maybe disconnect everything in a few hours?
Unlike weather forecasts these are actual storms. At this time of year especially, it is worth going to the linked maps to keep an eye on storm progress.

UK Weather Forecasts are Rubbish - NOT amateur radio
OK, I moan about weather forecasts a lot and here I go again.
Yesterday the forecast for OUR VILLAGE on the day said rain showers all afternoon. It was dry until we went to bed.
Today OUR VILLAGE was supposed to be dry all day. It is raining!
If you cannot rely on the forecast for NOW, what IS the point? Before readers tell me how complex our UK weather is may I say, yet again, our forecasts are rubbish.
The only reliable weather forecast in the UK is to look out of the darn window.
Millions have been spent on super-computers to enable better forecasting - oh yes?
UPDATE 1400z: Perhaps the best is to look at the forecast and assume the opposite?

All quiet so far on 10m WSPR and 6m WSPR
It is now, as I write this, 0800z. So far, both 10m and 6m WSPR have been very quiet although it is very early still. Certainly there have been no signs here of Es as yet.
UPDATE 1140z: So far just a single spot on 10m WSPR from HA9AL (1455km). Nothing as yet on 6m WSPR.
UPDATE 1306z: Apart from the above Es spot, just G4KPX (14km) spotting me on 10m WSPR. All still quiet here on 6m WSPR.
UPDATE 1342z: Spots exchanged with G4NRG (58km) on 6m WSPR. I am giving him much better reported S/N. OK, he is running a little more power, but maybe he has a higher local noise level?
UPDATE 1712z: OZ7IT (853km) has just spotted me strongly (+10dB S/N) on 6m WSPR. This is incredibly strong - more than a local! It implies just uW would have been enough.
UPDATE 1852z: OZ5XN (812km) running 5W WSPR was a colossal signal on 6m WSPR at +13dB S/N. Almost like he is in the same street!
