Sunspots today
Sunspot count today is down again, this time to 39 but 20-30MHz propagation remains "normal" so some decent F2 propagation is likely. I expect the USA to be audible around lunchtime onwards. These days, it is the norm. South Americans are usually copyable on WSPR as long as there are active stations.

First Spanish station logged on 472kHz
At 2352z last night EA3NE (1198km) in JN11an square in Spain was copied at -30dB S/N on WSPR. He is NW of Barcelona. This is with a totally unmodified FT817 (original version) and my "strapped feeders" compromise antenna.
On TX, sadly no new reporters yet again. I think on RX I have now received most of the active stations on 472kHz WSPR.

Back on 472kHz WSPR
This evening I have returned to my 5mW ERP WSPRing on 472kHz. As yet, just the same stations are spotting me and being spotted. All being well, I shall leave things running through the night. Hopefully the PC will not decide to close down at 3am as it did last night. G3ZJO is a better signal now and he seems to be receiving better. I am on the "strapped feeders" antenna tonight rather than the earth-electrode. Incidentally, SP5XSB has been very pleased with MF results with his low milliwatts ERP signal from his earth-electrode antenna.
UPDATE 1922z: F1AFJ (607km) is already being spotted here at -30dB S/N (just) at 1922z. He is some way down in France JN06ht square. Half an hour later he was 6dB stronger
UPDATE 2145z: F5WK (436km) has been spotted here 21 times already this evening on 472kHz WSPR. His signal has averaged about -21dB S/N so far, peaking at -17dB S/N. He is located in the Pairs area and claims to use 500mW ERP.

Driving again
For the last few days I have been allowed to drive the car again. It had been 13 months without driving because of my brain bleed. Several (safe) journeys later I am, at last, starting to think again about doing some field experiments. Local driving/sitting in the car is fine, but doing any physical activity tires me totally and I still feel very wobbly when on my feet. Doing the simplest of VLF or light beam field test is likely to exhaust me. Field work will be on the agenda soon, but I may need my wife to help set things up "in the field".

Predictable 10m WSPR
10m WSPR has been predictable again today with my first spot by a USA station W3CXW (5886km) at 1158z and several times since. CX2ABP (11127km) has been spotted here 9 times this afternoon already by 1414z. Conditions to North and South America are good on 10m today.
80m WSPR overnight
Unfortunately my Windows 7 PC decided to try an update at around 0300z so the PC (and WSPR software) closed down about then and never restarted until I helped it at breakfast time! All 80m WSPR results are before the (premature) close down or just after breakfast.
Best spot of my signal was from OH8HTG (2002km) a couple of times. Even my "useless" 80m antenna can get spots across Europe it seems.

Now trying 80m WSPR since 1812z
After the successes on 160m WSPR last night, this evening I am having a go with the "strapped feeders" antenna on 80m WSPR. The first 2W (from FT817) burst resulted in 5 reports across the UK, Belgium and The Netherlands. Reports are generally good. My first receive burst netted 3 stations.
UPDATE 1900z: A decent selection of Western Europeans spotting me and being spotted.
UPDATE 2135z: Best DX on 80m WSPR so far this evening is OH8GKP (1994km).

10m WSPR - busy today
10m WSPR is "humming" today with lots of stateside stations, Europeans and CX2ABP (11127km) coming through here or spotting my 2W. I have just downloaded beta release WSPR V4.0 r4171 which seems stable, but lacks the scrolling waterfall.

160m WSPR overnight
WSPR really is a very good mode. Overnight I left my 160m WSPR running, just using the strapped feeder to my V2000 and Par end-fed antenna tuned with an ATU against mains ground.
Even this most rubbish antenna seems to get me spots over 1000km on 160m WSPR when running 2W from the FT817. Although I claim 1W ERP, I suspect the real ERP is in the milliwatt region. Best DX spot was by SM7WZI (1007km) who copied me several times after midnight. Tonight, I may try 80m for a change.
On 160m WSPR receive the best DX was OZ7IT at 853km:
