Kazakhstan (again) on 6m JT65

UN7TW (5214km) was spotted on 6m JT65 this afternoon. This is a very long way on VHF. Although the considered view is this is multi-hop Es, I think some sort of chordal-Es is more probable.

UPDATE 1702z:  Still UN7TW as the best 6m DX.

Here's a dielema Roger,
I was transmitting both WSPR and JT65 sequentially from my U3 at 100mW on 6m. I was received in BOTH modes by SP7QLF at 1550km within a 3 minute time slot but my JT65 signal was logged at -18dB and the WSPR signal at -24dBm.

I would have expected the WSPR signal to have been better than the JT65 signal.

Any comment?

Ken, often with Es, the propagation can change within minutes. Also WSPR uses a 2 minute cycle whereas JT65 just 1 minute.
