Still life on MF and LF
It is some time since I was active on 137kHz and 472kHz WSPR, but there are still stations active I see. I shall return to 472kHz WSPR in the autumn and may even try some tests from this QTH on 137kHz. I do need a better antenna and earth system though. My earth-electrode "antenna" is remarkable, but I know I should be able to increase my ERP considerably with a loop or loaded long-wire. I managed 250km on WSPR with a loop at the old QTH on 137kHz and a vertical loop with similar loop area should be possible I think. I shall probably need help from locals with erection though in my present state. I might change to a 2m big-wheel stack at the same time?
Weeks since decent F2 spots on 10m here
Although EA8BVP (2986km) seems to spot my 500mW 10m WSPR signal on most days, it is some weeks now since I have been spotted on the band at greater distance. I know my antenna is not brilliant on 10m, but I was expecting more 10m spots from S.Africa and S.AmerĂca. I fear many have migrated to lower frequency bands now, which is a pity, or possibly other modes. At the last time I looked there were only 32 active 10m WSPR stations worldwide. A few months ago this was over 100.
Sunspots and 10m - June 24th 2015
Sunspot number has fallen to 61 (K=3) and 10m propagation is expected to be "poor".
UPDATE 1100z: K index has worsened a little to 4.

Nighttime DX on 6m
Although I was not spotted by any DX on 10m, I spotted on 6m WSPR, in the middle of the night at 2000km, a station in Finland (OH7AZL). Magic band! The "common wisdom" is this is Es although with these very northern openings especially at these odd times might be due to noctilucent cloud reflection? I wonder if any better equipped European stations were copied in Japan on 6m?

6m Es I presume
It is getting quite late in the day now, but I am spotting 6m Europeans by Es I assume. LA3JJ (993km), SQ6IUS (1158km) near Warsaw. As yet, I have not been spotted by any Europeans on 6m WSPR, just Gs. I assume this is Es, but these are all northern Europeans, so I always wonder if noctilucent clouds are someway involved? Probably not.
UPDATE 2214z: Sadly no Es DX appeared on 6m here after the LA3 and SQ6. I have checked all is well on 10m and 6m WSPR, so will run the station through the night, hoping to catch some DX by Es either overnight or first thing in the morning.

10m Es (no Es seen yet on 6m)
I4ZTO (1185km) was spotting me lunchtime on 10m WSPR by Es. On 6m, just locals and G stations by tropo/aircraft reflection.
UPDATE 1805z: Es on 10m from across Europe , but nothing like yesterday. 6m has only been G stations here all day so far.

Tidied the shack
I tend to use WSPR a lot at present because my voice is poor with 100% TX on 10m and 20% TX on 6m. I can be on both bands at the same time. Usually I monitor on a different PC in the lounge. If there is any problem I go to the shack to check and reset.
Although I have managed a little building, my fine motor skills are still far from good. The shack was becoming untidy. This morning I decided to give the shack a tidy! Although really superficial, it does look better. It is now XYL acceptable, I think.
UPDATE 1817z: My fine motor skills were put to the test today: my son managed to cut through the power cable of the hedge trimmer, so I had to mend it. I managed it OK and all was fine after I tested it.

Sunspots and 10m - June 23rd 2015
Sunspot number today is 77 with very disturbed conditions (K=8) and 10m - in fact all HF bands - expected to be "poor". Do not expect much on HF today. Es may give us some EU and possibly further DX on 10m and 6m.
Overnight and this morning I am just being spotted on 10m by local G4IKZ (18km). Although very early, no signs of Es here on 10m yet.
Best DX on 6m overnight was G0OQK (98km) - spots both given and received - and a single spot received from G8DOR (103km). A reminder that I use 1W ERP on 6m (V2000 vertical) and 500mW on 10m (Par 10/20/40m end fed low wire).
UPDATE 1026z: Conditions have improved a little with K=6 now. Still disturbed though.

New country (I think) on 6m WSPR
EA6GF (1428km) in JM19gm, has spotted me several times recently on 6m WSPR. This is the Balearic Is in the Med. Obviously Es. I have worked this country on QRP SSB on 6m in previous summers.
UPDATE 1428z: So far this summer, no sign of North African stations on 6m WSPR. In previous summer Es seasons CN8LI was a very regular reporter, but totally absent (for me) this summer.
UPDATE 1810z: 6m WSPR has been good all day with Es propagation. These are just the recent spots. As you can see, some of the signals are very strong.
UPDATE 1855z: Just exchanged 6m WSPR spots with CN8LI (2113km). Signals are strong too. Funny!

Thunder?
So far the weather here in East Anglia has been good today. I managed to cut both lawns this morning. It has just started to rain and there is a risk of thunder, although at the moment the storms are well east of this QTH. If the storm risk persists, I shall disconnect rigs and the PC. The rain is, of course, Sod's Law as I just erected the hose to water the grass later!
See http://www.lightningmaps.org/realtime?lang=en .
UPDATE 1445z: The sun is now shining again.
UPDATE 1706z: Thunder and lightning appeared here at 1645z, so I have closed down on both 10m and 6m, disconnected the antennas and the PC. According to the thunder maps, the storm was about 2 miles or less to the west. I'll monitor the maps and return to 10m and 6m WSPR when the storm has passed.
UPDATE 1810z: It looks like the storm has passed, so I have recommenced 10m and 6m WSPR.
