JT65 is proving useful for finding brief Es openings on 6m. In the last hour WN5LUF (6886km) in Missouri just appeared and disappeared. Maybe others will appear and maybe not. Earlier in the day a station in New England just came and went on 6m JT65.
Although you might expect 10m WSPR to be better, I seem to get better results on 6m JT65. This could be down to antennas, although there seems to be more activity on 6m JT65 than 10m WSPR.
