I thought I had worked them on 40 meter CW several days ago. The operator had my call wrong but patiently listened for a correction and came back with the correct call. However it never made it into their ClubLog page.
Today the conditions were pretty good from 3 PM local to 5:30 local — good strong 40 meter RTTY signal on 7.044.4 (tones up 1500 Hz). After almost 2 hours of calling I finally got a response!

The pileup was about 15 KHz wide. At the time it was running about 8 JA stations to 2 US stations (with EU asked to standby).
