472kHz WSPR - RX only now with preamp
Since 2055z I am on 472kHz RX only with the preamp in circuit. I shall stay on overnight to see if any new stations are copied. Up to now the conclusion is the preamp improves the sensitivity and S/N of stations, but I have copied the same stations without the preamp. What I need are a few new (to me) stations right on the threshold of copy.
Interest rates - NOT amateur radio
It has started. Gradually rates will rise across the world.
People had better get ready for life when borrowing costs more. I can
remember when interest rates hit 15% and mortgages were very expensive. At the moment borrowing (and being in debt) is very cheap, but history tells us these days will not last.

SLOWLY declining solar activity
The slide down from a solar maximum is (usually) slower than the climb from the minimum to the maximum. Very gradually, the sun is going "off the boil" and solar activity is slowly falling away. With each year for several years to come things will get progressively harder on the higher bands. Some are predicting the next maximum may be a "damp squib", so enjoy the conditions while they last. It is quite possible that 10m will never be as good again in the lifetimes of many of us. Certainly 10m is already not as good as a year ago. Although Es is good at any part of the cycle in late spring and summer, F2 DX is best around the peak of solar activity. In the past 6m has supported worldwide DX at times, but I think those days are sadly over.

Pruning - NOT amateur radio
At the moment, it is unseasonably mild for December here in the UK. Often at
this time of the year it is very misty and cold but at the moment it is
about 14 deg C and every chance of it getting even warmer. The grass is still growing. I cut it 2 weeks ago and it could really do with cutting yet again. Normally I stop cutting at the end of October.
Today, in between bursts of total exhaustion (stroke after-effect), I pruned two bushes in the garden. Working outside it felt more like April than December. I also noticed quite a few bulbs pushing through. Unless we get a really cold January we will soon have daffodils in bloom in the garden. Another 2 weeks? The ornamental cherry in the lawn needs a trim. This will have to wait.

More WSPRnet issues
Like many, I monitor WSPRnet to see who I am spotting and who is spotting me. In my case I often do this from the comfort of the lounge, whilst doing other things. I notice that WSPRnet is very slow again today. In fact, the last few times I tried it failed to connect at all.
UPDATE 1525z: WSPRnet seems to be working at the moment with a 472kHz spot of my 5mW ERP by M0LMH (223km) a short while ago. Sadly if WSPRnet is not reliable it rather ruins the "near instant feedback" of WSPR.
UPDATE 1652z: If WSPRnet really is just done by volunteers for free I am amazed it is as good as it is. I for one just use it and milk it. Like many, as anonymous says below, I'd happily chip in some cash to help provide a reliable service. Not all can afford to do so, but I use WSPRnet each and every day just about. Without WSPRnet, WSPR would not be a quarter as good as it is.

10m winter Es?
With several 10m WSPR spots received from Italy and Germany, I am wondering if this is winter Es? It is the right time of year and the right time of day. The main Es peak is May, June, July but there is often Es around Dec/Jan too. The peak is smaller, but it does happen. So far, no DX spots from further afield by F2 propagation.
Bargains - really?
Many of the larger dealers are offering special deals in the lead up to Christmas. But, are you really getting a bargain? For example, MLS have the FT1200 at less than £1000 after cash back. Maybe this radio is over-stocked as people prefer the IC7300 or the FT991?
Call me a cynic, but I think we are being offered discounts on radios that have not sold. As they say, "beware of Greeks bearing gifts". If something looks too good there is probably a catch. Of course, if you really want one of the discounted rigs then now is as good a time to buy as any.

No surprises on 472kHz overnight
With the same stations logged on RX and the same stations copying me on TX, there were no surprises on 472kHz (630m) WSPR overnight. We need more active stations on 472kHz WSPR.
Sunspots and 10m - Wed Dec 16th 2015
With a solar flux of 122, sunspot number of 64 (K=1) and 10m propagation expected to be "fair" today, 10m WSPR could be in reasonable shape today.

QSYed to 472kHz WSPR
About an hour ago I QSYed to 472kHz WSPR and went QRT on 10m and 6m. Although both EA5DOM (1525km) and PA3ABK/2 (306km) have been spotted, these did not upload to WSPRnet as my shack PC lost its internet connection. I have rebooted the PC, it has done its updates and seems to have the wi-fi/internet back in service since about 1900z. Let's hope it stays working!
UPDATE 2110z: All seems to be working on 472kHz WSPR with the internet connection to WSPRnet working from the shack PC. EA5DOM (1525km) is still the best DX on RX (no preamp) and DL-SWL (701km) the best DX on TX (5mW ERP) tonight.
