There's no secret to the confirmation rate except that I am biased to work stations that have recent uploads to LoTW. DX Suite Spot Collector highlights the spots differently, that's where I focus first.
This last week brought me (possibly) 3 or more new dxccs. I've worked the T30UN expedition on 5 or 6 bands now, and I worked the 4W1A group on 20 RTTY this morning. I worked them Friday, too, but that contact was not in their log, but today I am in the log. Plus the VU7W this morning on 10.
Gotta go turn the crank some more.? PLUS... 6M e-skip season is coming soon...
