PU3RRW (10652km) was spotted 3 times (so far) this evening. This station in GF38tf is about as far south as one can get in Brazil and was a massive +9dB S/N for 5W on WSPR at times.
I wonder if TEP propagation was helping to give signals this strong on 10m.

More transatlantic 10m
Atlantic |
PY2RN (9550km) has been spotted on 10m WSPR several times already today. Southern Brazil is a long way from the UK but it is mostly a sea path.
10m oddity
10m WSPR early morning April 11th 2014 |
KH9/WA2YUN is shown as Wake Is, so this is probably genuine.

A glutton for punishment? 474.2kHz WSPR
I have just gone back on to 474.2kHz USB dial WSPR with 5mW ERP from the 15m spaced earth-electrode antenna. I must be a glutton for punishment!
So far this evening I have seen a couple of different Dutch stations and I have been seen a couple of times by PA3ABK/2 (306km) and once by F1AFJ (607km). The kit will be left on overnight to see if any new stations turn up.
WWV at 25MHz
The Southgate Amateur Radio News Page reports that WWV (Fort Collins) is experimenting at 25MHz for the first time since 1977 for a limited time.

6m TEP in the Far East and 10m propagation today
Over here, I can see no South African or other African WSPR stations active making 6m TEP attempts here a waste of time.
Later unique 10m WSPR spots of my 2W until 1744z. |
The first transatlantic spot was at 1108z when W4HFZ was copyable at 6819km. He was using 5W. There are other 4 area stations being copied too. The pattern this afternoon is similar to previous days on 10m.
My best DX today is FR1GZ (9724km) at 1550z. Just now I was spotted by VE6ODQ (6640km) in DO34ir (Athabasca).

XP3A - Nook, Greenland on 10m WSPR
For some reason (Win 8.1?) I have had issues today uploading my WSPR spots (that is of others) to the database. I have restarted the software and reset the clock and now all seems to be OK. Among the first uploads was a strong signal from XP3A in Nook, Greenland at 1932z.. Although strong (+4dB S/N) there was -4Hz Doppler on the signal, perhaps because the signal was coming through the Auroral Oval?
This was the first time I have seen/heard Greenland on 10m WSPR but I was lucky enough to work Greenland on 15m SSB handheld with my FT817 in my back garden some years ago on just a base loaded whip with a counterpoise! I think the mode then was double hop Es. It was an easy QSO. Being able to move the antenna for best signal helps.
Interestingly, a VE4 was suffering -4Hz Doppler just now (signal again passing through auroral oval?). I often see large Doppler shifts on signals crossing the Equator (e.g. on FR1GZ) and I assumes this is due to moving F layers (spread F) as signals cross the magnetic Equator. I would expect TEP signals to have considerable Doppler too.

Phlatlights
When I have repeated my over-the-horizon NLOS optical (red LED) tests at 481THz using LEDs bought from Hong Kong, I must remember to try my Phlatlights which are about 10dB stronger. I bought these nearly 2 years ago and have not yet fired these up! The ones I have already have heatsinks so it should be quite easy to use these for QRSS3 tests. In theory it should mean aiming a little less critical or greater range when "on-beam".
At 8.7km over the horizon with a clear sky, QRSS3 signals were about 10dB S/N with the 10mm HK LEDs, so with Phlatights and the same optics (100mm lenses) signals should be much stronger. More tests for when I am fitter.

10m today - still good

This weekend I may make a start on my Ultimate 3 WSPR beacon kit (see image above on Hans Summers' site). This is a complete (no PC needed) beacon kit for modes like WSPR and QRSS3 and very reasonably priced even if buying the GPS timing kit too. Mine cost £37 including postage from Japan with GPS.
I feel a bit better than I did and less clumsy. We'll see.

10m yesterday - a remarkable day
10m yesterday was quite remarkable here.
Nothing at all was seen until mid-afternoon and then the band just opened wide! K9AN (6505km) last spotted my 2W signal at 2308z, which is after midnight local time and HOURS after the band has normally died out. It had been dark for hours. One wonders if this was F2 or even multi-hop Es? I wonder what was happening on 6m transatlantic? I must check.
Even this morning conditions are encouraging with US7ISA (2634km) spotting my 2W as early as 0750z - very early and much earlier than stations were coming through yesterday. This is eastern Ukraine. Probably F layer but could, I guess, be early Es propagation.
