UPDATE 1435z: More South Americans spotted (Uruguay and Northern Brazil) so 8 South Americans spotted so far. Canary Is, EA8CYL (2988km), is the best DX yet on 10m JT65 TX. I think the European spots may be Es.
UPDATE 1446z: No signs of the USA on 10m JT65 as yet. It is about this time I'd expect this path to briefly open. Maybe later in the month?
UPDATE 1504z: Another South African spotted on 10m JT65. ZS1ALJ (9697km) around Cape Town spotted. BTW, Cape Town is a beautiful city. South Africa is a beautiful country, although we get more insects in our bedroom in 1 night than we saw in the whole of South Africa in several weeks! Seeing "the big 5" animals wild in the Kruger National Park was splendid though. South Africa surprised us. It was far greener than we expected and the scenery was so different depending where you were: some places were like Scotland, other parts like the Med, and other parts wild open plains. It is not a place I'd like to live, but it is well worth a visit if you get a chance. We went a few years ago.
UPDATE 1645z: ZS1CM in Western Cape has also been spotted on 10m JT65. Currently 13 different South American stations spotted on 10m JT65.
