Another Indonesian on 6m JT65?

Today, out of the blue, I (supposedly) spotted 7A4TOI (13582km) in Indonesia at 1145z on 6m JT65. Although this could be genuine, I am pretty sure this station is a pirate somewhere in Europe. It would be great if this was a true 6m spot.

UPDATE 1933z: The Caribbean and South America now being spotted on 6m JT65. I think these are genuine!

Sunspots and 10m - Saturday June 17th 2017

Solar flux is 74 today and the sunspot number 28. A=24 and K=4. 10m? Maybe Es but F layer doubtful, especially with K=4.

UPDATE 0915z: No sign of Es on 10m or 6m here yet.

What a difference a day makes

Yesterday I had spotted lots of Japanese stations by now on 6m JT65. Today my only spots so far on 6m JT65 have been G stations. No Es yet on the band here.

UPDATE 1330z: Some Es now on 6m JT65.

Long long 6m JT65 paths - what mode?

The very long paths on 6m JT65 are intriguing me. The common wisdom is these are "multi-hop sporadic E". Sorry, but I just don't believe it.

Some paths may be multi-hop Es sometimes (e.g. to Israel) but I think we are seeing some other sort of E layer propagation, maybe some sort of chordal hop? The Far East spots may be due to mesospheric cloud ionisation?

Some of the very long 6m paths may be pirates, but the Japanese spots are genuine and have occurred several times already in the last few weeks.

I am no propagation expert, but would love to hear from experts who might really know what is going on.

We are in 2017 and there are still unsolved mysteries.

What amazes me is there appears to be no-one trying to span Europe to Japan on higher VHF bands or even microwaves. This path opens every year at this time on 6m and should be possible at higher frequencies especially with big antennas and high power such as stations equipped for 23cm EME. Suitably equipped stations know where to beam, know when, know the best times. So? If you are suitably equipped set up some skeds!

Sunspots and 10m - Friday June 16th 2017

Solar flux is 77 today. Sunspot number is 28 today. A=4 and K=2. 10m? Well there is plenty of Es on 10m and 6m, but no F layer propagation noted here.

13 Japanese stations spotted today on 6m JT65

This is the best day so far this season on 6m JT65 with 13 (thirteen) different Japanese stations spotted around breakfast time today. Interesting that none at all was from Tokyo or its suburbs. Sadly, no spots of me from Japan.

I am amazed how easily I am spotting these with my poor setup here.

At the moment, I am still on 6m JT65 in beacon mode sending "B G3XBM JO02" near the top of the JT65 sub-section.

UPDATE 0932z: as well as all the Japanese spots on 6m JT65 I notice 7A7YYZ (13582km) was spotted early on 6m JT65. If genuine, this is long way on a VHF band. I have spotted different Indonesians several times, and find it hard to think they are all pirates. There were so many Japanese that I am sure Far East 6m propagation is genuine.

Gilbert and Sullivan - NOT amateur radio

Every year, about this time, we attend a performance of Gilbert and Sullivan (Victorian comic opera) in a barn in a local village. This is an amateur cast but the performance is always first class. This year they did "Princess Ida", a work with which I was not familiar.
