Amateur satellites
In all my time in amateur radio I have only had 1 QSO through a satellite and that was many years ago from 10m to 15m. I have rarely used low orbit satellites. In my early days I had fun listening to the download frequencies of Oscar 6 and 7. I recall hearing North Americans on 2m on late passes.
Sunspots - Monday July 29th 2019
Solar flux is 65 and the SSN 0. A=4 and K=2. Basically rubbish.

6m propagation from Europe to Australia
When I first heard of this I was sceptical, but the more I read the more I think this is true.
Apparently several stations were worked, so this very unlikely to be pirates. This appears to be E layer propagation, but multi-hop Es seems to be very unlikely. I am sure some of these long "real DX" paths are not multi-hop Es. As this was at the same time as a 6m opening to Japan on 6m, there is some speculation that this is whatever E layer propagation gets to Japan plus some TEP.
See southgatearc.org/news/2019/july/unusual-opening-from-europe-to-australia-on-50-mhz.htm

Oscar 100 - geosynchronous amateur satellite
As many will recall, I take the occasional peek at the Goonhilly web SDR, which monitors the narrowband transponder on Es'hail satellite, also known as Oscar 100.
In my view activity seems lower than a month ago. Certainly activity is not great and has definitely not increased as I once expected. Looking just now on a Saturday afternoon, the most I saw were 5 stations active on SSB at one time. By now I was quite expecting the main issue to be too many stations, possibly overloading the transponder.
It seems people have fun getting a signal through the satellite, then lose interest.

Scrabble - NOT amateur radio
It was a dull, wet day today, so we played Scrabble with the grandchildren. Our younger granddaughter kept score. She is better this time! The last time she played she forgot to record some scores.

Pye PF8 transceiver
In its day, this was a "state of the art" transceiver made by Pye Telecom. One of my early jobs was being part of the design team for this. We had all sorts of issues with the DC-DC converter noise. On my website is a PDF of the manual which may help some who convert these to 70cm amateur use.
They are quite rare and hard to find. Before you ask, I do not have one and do not know where to find one! Your best chance is on eBay I guess.

6m FT8
So far this morning, 11 stations spotted on 6m FT8 RX in the last 6 hours. As I write it is 0848z. So, early Es on 6m.
UPDATE 1413z: Now 54 stations spotted on 6m FT8 RX today.
UPDATE 2000z: Now 71 stations spotted on 6m FT8 RX today. All European and just one Moroccan spotted.
UPDATE 2040z: Although it is unlikely I shall spot much overnight, I am still on 6m FT8 RX, in the (slim) hope of a late opening or very early Es tomorrow.

Early logbooks
On my main website are some of my early logbooks. These are available as PDF files. These copies were made years ago. I have no idea why only some are there. Perhaps I was unable to locate some at that time. This must have been 12 years ago or more.

York Chocolate Story - NOT amateur radio
One of the things we did in York with the grandchildren was go on a one hour tour called "The York Chocolate Story". It was very good. At the end of the tour the little ones got to make chocolate lollipops.
Overall, the stay in York was very successful with the little ones having a very good time. For the first few days it was very hot, with high temperatures, although we had rain and (a bit) cooler weather on the last couple of days.

Back on 6m FT8
For the last few days, we have been in York with 2 of our grandchildren. Since returning home I have been on 6m FT8. This has been mostly RX, although a brief CQ got no 2-way QSOs, but was spotted by 6 stations including 3 in eastern Europe. On RX 21 stations spotted with the best being 9K2YM (4714km) in Kuwait.
UPDATE 2124z: Now 31 stations spotted since we returned mid-afternoon.

More spectrum available to share
OFCOM today announced that additional spectrum is expected to be made available. See OFCOM's website for more details. As far as I can tell this is just certain microwave bands.
Heat - NOT amateur radio
In the UK we are not used to the heat. In London it has been in the high 30s.
DXpedition to St Paul Is
There is a DXpedition to St Paul Island off Canada at the end of the month and early August. There is a piece on Southgate News about this.

Storm risk
We had thunder and lightning here last night but the storm risks have, for the moment, decreased as they have moved further east.
23 Jul 2019
Thunder risks
Over the next few days it is expected to get very hot in the UK. So hot that records could well be broken. With this can be a risk of thunderstorms, so I am QRT at the moment "just in case". The risks may be low, but I tend to disconnect antennas and power plugs.

Yet more houses - NOT amateur radio
It seems that every spare space in our village is used to build new homes. There are very few homes that "ordinary" folks can afford. This is a common story in many parts of the UK. Most being built are "executive" homes i.e. those that give the highest profits for the developers.

6m FT8 Es DX
At the moment (simply as it is convenient) I continue to monitor 6m FT8 RX. Already at 0800z there is plenty of Es DX coming through from southern Europe. So far, in the last 6 hours, 15 stations spotted.
UPDATE 0840z: A single 15 second CQ brought 8 spots with the best being CT1ILT (1436km).
UPDATE 1043z: Now 45 stations spotted on 6m FT8 RX in the last 6 hours, many by Es. All Europeans.
UPDATE 1525z: Supposedly TU2EZ (5209km) spotted. This could be genuine, but most of his spots were in the UK, so I am suspicious.
UPDATE 1852z: A recent CQ resulted in spots from all over southern Europe. My best spot was by CU2GI (2575km) in the Azores. So far today, 193 stations spotted, mostly Europeans by Es. Now QRT as we may have lightning later.

Es (sporadic E) propagation
Although in the northern hemisphere this tends to be best around May-August, it can occur at any time of the year bringing huge ranges on the VHF bands. There tends to be a smaller peak around December-January.
Southgate News has a link to a piece on Es. In my view, despite having experience of Es since (at least) the 1930s, the world still has much to learn about it.

Swifts - NOT amateur radio
Swifts are gathering in great numbers. This evening there must have been 50 or more on the wing eating insects on the wing over our heads. Many must be this year's youngsters.
In about a month most will be gone. The screaming will stop one day and we will realise the great migration has happened. It amazes me that these birds fly so far every year. Then we will have to wait until next April to see them again.

French animal deaths - NOT amateur radio
It seems (according to the BBC) that animals in France are dying in numbers far higher than expected for unknown reasons. Some of these deaths are near wind farms and mobile phone masts. Research has so far been inconclusive. It is odd and unexplained.

The next US president? - NOT amateur radio
Here is a puzzle. Enough people in the USA loved President Trump to get him elected whereas almost everywhere outside the USA he is viewed as a fool and incompetent.
It is honestly true that I have interacted with not a single person outside the USA that has a good word for him. Truly. Perhaps his "make America great again" mantra finds favour in the USA. Perhaps he will even get a second term in office.
There seems a great lack of real leaders in the world currently. Most seem to seek power for their own good rather than because they seek a greater good and are great statesmen. Given time, I hope this will change.
We need leaders with vision to see beyond their own self interest to the greater good of their nations and the world.

Great Es on 6m
Currently I am on 6m FT8 RX and there is a great Es opening, if not the best this summer. Although it is only 0853z 113 stations from all over Europe already copied.
Sunspots - Monday July 22nd 2019
Solar flux remains stubbornly at 67 and the sunspot number still 0. A=8 and K=2.
This feels, very much like sunspot minimum. At least we can look forward to better times, if not the great times of 60-70 years ago.

New friend? - NOT amateur radio
My daughter-in-law and 2 of our grandchildren are staying with friends in Suffolk.
Our granddaughter seems to have made a new friend that comes every time she calls it! Earlier in a video chat it sat on her shoulder then the phone!

Es' Hail satellite
As many will recall, I occasionally look at the activity on this geosynchronous satellite using the Goonhilly web SDR. As far as I can tell, activity levels are much the same as a few months ago. Some new people have come and some have gone. Most times there are around 6-8 active stations. At the moment I am not inclined to assemble gear for Oscar 100.

6m FT8
Good Es this morning on 6m. My brief CQ was spotted by 16 stations (no QSOs) as far away as Sardinia. On 6m FT8 RX 19 stations from all over Europe copied so far in the last few minutes.
UPDATE 0848z: 36 stations so far spotted this morning on 6m FT8 RX. My theory about most Es openings late in the season being to northern Europe is being tested! 😕
UPDATE 1400z: Now 158 stations spotted today on 6m FT8 RX with best DX being N4BP (7118km) in Florida, USA. A good day on 6m.
UPDATE 1614z: Now 206 stations spotted today on 6m FT8 RX. Just recently, Israel spotted.
UPDATE 1802z: Now 280 stations spotted on 6m FT8 RX today in 4 continents.
