With good Es still on both 10m and 6m, I am reluctant to swap from JT65 on 6m to JT65 and JT9-1 on 10m. As I've said before, it is a case of "either or" on 10m JT65 as I cannot use my W5OLF beacon stand alone as it only works on 10m WSPR. For 10m JT modes I need the FT817 and the PC. I am sure there is more activity on JT modes (certainly true on 6m).
Even though JT modes are less good than WSPR, this is made up for by the 1 minute cycle time and greater activity. I shall probably swap to 10m JT modes mid-August.
