Es propagation late in the season

It is very easy to generalise, but my experience is that 10m openings to more northerly stations become more common later in the season. If this is statistically significant (and I could be wrong) I have absolutely no idea why this should be so. As an example, there have been lots of 10m WSPR spots from the Faeroe Islands, Denmark and Germany today, but few from southern Europe.

Am I wrong? Have others seen this?

October QRP days for your diaries

From Oleg:

"Dear QRPers,
keep in your diaries the period of October 4 to 17.
This is a Sputnik QRPp Activity Days.
Categories:
- Sputnik
recommend  to  use  old  type  valves (preferably 1950-60-th), output
recommend  1  watt  or  less.  Series of "beep-beep-beep..." required
before or after transmission session;
- Vanguard
recommend  to  use  simplest  TX  with  Ge old type p-n-p transistors
(1950-60-th),  output  recommend 100 mW or less. Series of "V V V..."
required for identification;
- SWL
they must to log any TX sessions of Sputnik/Vanguard. High profile to
use  old type receivers (50-60-th produced) or home made RXs with old
type components;
Beacon  TXs accepted as Sputnik/Vanguard, identifications "beep-beep"
or "V V V" required.
Every  day  log  send to the "Center of Deep Space Communications" to
duty operator "mr72" :-) The each days totals will be published on the
Club 72 page daily.
Memorable  certificates of "Cosmonaut" or "Astronaut" will be sent to
each participants.
See  full  rules  on  the  Club  72  page, please. Last years results

Iceland - NOT amateur radio

Some years ago now we visited Iceland and were surprised just how beautiful it was. The photo shows where the first Icelandic parliament was held. I think this was 960AD.  This is on a fault line. There were lupins everywhere.

10m WSPR TX (Wednesday)

After several days now of decent Es on 10m, we are due for a quiet few days this late in the season. As usual, I am on 10m WSPR TX (500mW) ever hopeful.

UPDATE 0848z: Lots of Es spots by OY1OF (1164km) and some of his reports were very strong.

UPDATE 0950z: 3 unique spots so far this morning of my 500mW 10m WSPR beacon. Best DX is currently EA1KV (1304km).

UPDATE 1218z: Lots of Es again, with 7 unique 10m WSPR spots so far.

UPDATE  1345z: Now 13 unique spots of my little 500mW 10m WSPR beacon today.

Reach - NOT amateur radio

Our nearest village is Reach. This has no shops, one pub owned at one time by the villagers and is at the end of an earthwork built about 1400 years ago called the Devil's Dyke. At one time it was an important Fenland port. It still has one of the oldest fairs in the land opened by the mayor of Cambridge. The village green (shown in the photo) is in the centre of the village.

Just how do they do it?

The Banggood portable BF-UV8D retails on eBay for just  £14.25 with free shipping to the UK from China. In all honesty, just how can anyone compete?

This is a 5W RF 400-480MHz transceiver and comes complete with charger, back clip, antenna and battery. If I was Yaesu, Icom and Kenwood I'd throw in the towel now. Once the Chinese really wake up, the Japanese manufacturers have no chance of surviving. The Japanese will be driven more and more to niche markets, then die. I cannot see them staying around in the amateur market for too long.

At the moment the Japanese have quality on their side, but the Chinese will soon be as good. At the moment it seems everything, just about, is made in China. Recently I bought some Olympus binoculars - these said "Made in China". The Chinese seem to be able to make most things at prices that simply cannot be matched.

20 years from now we'll be living in a very different world.

You can buy a 433MHz module for just over £1 with free shipping from China!!

They make profits too, so how do they do it?

Drone - NOT amateur radio

Last night we had a drone above our house. I think it was taking photos of "our" windmill next door. I have mixed feelings about drones. They allow some very good photos and videos to be taken, but their uncontrolled use could be dangerous. Personally, I am in favour of some sort of licence.

UPDATE 0840z: Apparently the drone was inspecting the windmill sails (next door) to make sure they are safe.

6m FT8

It seems obvious to me that FT8 has become the de facto mode for digital QSOs on 6m. Bandwidth is narrow, it is better than CW and QSOs can be fast. Once again, I am monitoring 6m FT8 RX in the hope of catching some Es.

UPDATE 0838z: Best DX already is IZ7FLP (1840km) by Es.

UPDATE 0906z: Already 6m FT8 is going great with 6 countries spotted with the best DX being SV9RGI (2776km) on Crete. Yet again, good early Es.

Sunspots - Wednesday August 30th 2017

Solar flux is 85 today. The sunspot number is 35. A=10 and K=1.

QRT on all bands

The big plug was pulled at 1925z and I went QRT on all bands until the morning. In the end, Es was good yet again on both 10m WSPR and 6m FT8, even though it is late in the season.
