Although there have been several openings from the UK to South America on 10m JT65 in the last week, I am beginning to think people are leaving the band and choosing lower bands on which to operate. This is a pity as it is rare for 10m not to open somewhere each week. It is not like the peaks of the solar cycle and the DX is certainly harder to find, but it is there on most days if you choose weak signal modes.
It you just want to chat, use lower bands or even Skype on the internet. If you want a challenge stick with 10m and switch to weak signal modes.
