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:

Sunspots
Today's sunspot number is 90 (still going up again in recent days) with 20-30MHz propagation "normal". Conditions on 10m should remain good again. USA stations should be audible very soon again as well as South Americans. In the last few days, lack of activity rather than conditions have been the issue on 10m WSPR to South America.

160m WSPR
For a total change I have fired up the "strapped feeders" antenna on 160m WSPR. No spots yet given or received, but UK/Europe activity is very low so far this evening. If I manage to get out on 472kHz, it should work OK (but not brilliantly) on 160m.
Last night I meant to go on 70cms for the UKAC activity session, but I completely forgot about it!
UPDATE 1845z: Best DX report, of me, is from OZ7IT (853km) at -24dB S/N. My power out is 2W. My ERP (claimed as 1W) is more probably in the low mW region. I'll stay on 160m this evening, and probably overnight.

Will try a new band later
Later today, or this evening, I shall try WSPR on a new band, probably 160m or 80m with the "strapped feeder" antenna via my ATU. Both 630m (472kHz) and 10m are getting rather predictable! 160m or 80m will make an interesting change I think. I may try 60m too as I hold an NoV.
