I've been running FT4 for a while now. 20 meters usually has the most activity. I've had 41 contacts this month so far. Most have been on 40 and 20. A few have been on 15. 15 is very spotty. 20 is the best.
I am usually around on one of those band from 1500 to 2000 UTC several day a week.
I'll watch for dates and times for FT4 Roundup.
Keep On Ham'n
