Much to my surprise W4MO (7177km) running 1W from Florida, has just been spotted, by me, on WSPR at 2120z and 2128z.. After the mainly N-S propagation this came as a surprise.
With a lot of Doppler (2Hz) I wondered at first if this was coming by moving spread-F from clouds close to the equator? We saw similar a few evenings back. He has just spotted me (-26dB S/N) with 0Hz drift, so that is my spread-F theory gone out of the window!
Still puzzled why just W4 (Florida) call area though i.e.. only lower latitudes of the USA.

GB3VHF
The GB3VHF beacon on 144.430MHz (and soon to be GB3UHF on 432.430MHz) is 107km more or less due south of here. Although it is decent signal on the 3el beam, it does not move the FT817 S-meter.
Does anyone know roughly the difference in the Cambridge area of this compared with the old Wrotham beacon? As I recall it Wrotham was a lot stronger.
A weaker signal is no problem, but I hope it is not just me that gets the Fairseat beacon on the North Downs in Kent weaker than the old Wrotham beacon used to be.
I expect to be able to copy the GB3UHF beacon when it comes on-air on 432.430MHz. Currently it is awaiting site sharing permission. It already has a licence from OFCOM.

10m - all N-S so far today
No signs (yet anyway) of North American stations. PY4AJ and FR1GZ are there, along with others, but all these are N-S rather than E-W paths. I suspect this is going to be the pattern in the months ahead with fewer openings across the N.Atlantic. Summer time we will get a few E-W openings on 10m and 6m by multi-hop Es too.
The path to 4X1RF seems to be regularly open. This is a single hop by F-layer.
UPDATE 1800z: IK1WVQ has been consistent in the last hour. I assume the propagation is Es. IZ6QZB is spotting me.
UPDATE 1902z: EA5CYA being spotted. Es.
UPDATE 2050z: M0MVB (30km) the only station exchanging spots with in last hour. Has the 10m band died out for today? No, then I spot EA5CYA again!
UPDATE 2110z: After resetting the clock and restarting the WSPR software (yes, it had stopped) I see that EA5CYA running 200mW WSPR is still a decent signal. This must be Es.

Unique 10m WSPR spots to 1420z
No stateside spots yet today. These are the unique station spots on 10m WSPR today. Most were spotted many times.
Slow deep fading on 2m
As the PI7CIS beacon on 2m seems a good propagation indicator it was interesting to see what happened in the rain today around 1325z. Whereas the beacon seems to be nearly always copyable, but not moving the S-meter on the FT817, it was in a deep,slow fade around 5 minutes long just now - still there, but maybe 6dB weaker. Looks like it is copyable most of the time but a bad fade would make it not readable.
10m WSPR - 0845z start today
An earlier 10m WSPR start today. Sunspot count 81 and 20-30MHz conditions "normal" so expect some Asians and South Americans and even a chance of N.America later in the day.
On 2m, the PI7CIS beacon (228km) is a consistent, if weak but fully readable, signal but the co-sited 70cm beacon cannot be detected at all.
By 0854z EX1UN and DL5ZBS had been spotted here and 4X1RF has spotted my 2W strongly twice. At 0907z FR1GZ (9724km) was spotted with a good signal. Everything as expected.
UPDATE 1120z: As well as a good crop of DX, there are plenty of EU stations in this morning's WSPR log including F, LA and DL These could well be by Es propagation.

10m WSPR this evening and (maybe) PI7CIS UHF?
Because of various non-radio factors I was " late on parade" getting on 10m WSPR today. I did not turn the rig on until 1750z. As yet, no spots given or received, but sunspot count is 80, and 20-30MHz conditions supposed to be "poor" with quite disturbed conditions.
UPDATE 1834z: At 1832z just spotted CE3YP (Chile, 5W, FF46qn, 11742km) at -24dB S/N.
The other RX (70cms on the 5el beam), may have detected faint traces of the PI7CIS beacon on 70cms. Signals were well LF of the indicated beacon frequency (about 1kHz) and were too weak to copy the callsign. There was something there for about 5secs at RST229. Looks like this beacon will only be copied under lift conditions.
UPDATE 1915z: At 1906z PY2RN (9550km) was spotted at -14dB S/N. A little later he was -9dB.
UPDATE 2030z: No further reports in the last hour. Unless there are very late surprises, like last night, this is probably it for tonight. I was surprised to spot Chile and Brazil on 10m WSPR!
UPDATE 2100z: I have closed the station for the night. A last look for PI7CIS (UHF beacon) was not successful.

VHF/UHF beacons PI7CIS Holland
Although I can copy the VHF beacon PI7CIS (144.416MHz) almost 100% of the time on my small 3el VHF beam (callsign clear but S-meter does not move on FT817) I have still to copy the co-sited UHF beacon with the same callsign. On UHF (432.416MHz) I have the same low loss coax (Westflex) and a co-located 5el beam on the very same beam heading. I know this beacon is not GPS locked, so it may drift, but I am surprised not to have yet detected it at all, even allowing for the additional losses in the feeder (maybe a few dB?).
Indications are this 75W, coastally located (Scheveningen) beacon, is operational, unless anyone knows better? The antenna is reported to be a dipole aiming 90/270 degrees which would be poor in my direction.
Anyone know the PI7CIS UHF beacon's current status please?

The next solar cycle?
Many are suggesting the next solar cycle (cycle 25) will have a very small peak and that we may even be entering a period with very few sunspots, not unlike the Maunder Minimum of the late 1600s. Truth is no-one can be sure. If it happens, the best propagation on 10m will be summertime Es - no bad thing. We will have to use 10m mainly for local traffic - it is a big band and a good choice for this.

Beacon hunting
Maybe tomorrow evening I need to do a good search for 70cm beacons in range under (near) flat conditions. There is a distinct lack of UK 70cm beacons, with even the very good GB3BSL beacon near Bristol now QRT. This would have been copied, I feel sure, at this QTH. Some of the nearer European ones may be receivable. PI7CIS (on 70cm) is probably my best hope. I can copy the co-sited 2m beacon.
