QRZ's 12 days

I had a go at QRZ.com's 12 Days of QRZ challenge which began in December. QED, all you needed to do was make one acknowledged QSO per day for 12 days. I concentrated just on FT8. But there are endorsements for 12 QSOs over 12 days per each band in the challenge: 160, 80, 60, 40, 30, 20, 17, 15, 10, 6 and 2m. I managed all bands between 80 and 15, can't transmit on 160, 6 was always closed when I tried, and 2m would only yield one or two close contacts anyway. So I ignored those. I had had little success with 10m but later decided to have a go. Overall 10m seemed to come alive most days and all went well until the last couple of days where there were plenty of QSOs but very few acknowledgements in the QRZ logbook, some of which were only as a result of importing form LOTW. A table of this for no particular reason:

DateQSOsStars
18/144
20/111
23/132
25/132
26/132
27/121
28/162
29/111
20/122
1/211
2/2123
3/2121

So I had to work those last two days. I had a go at FT4 as well and one each of the 'Stars' for the 2nd and 3rd February were from FT4 QSOs.

There, a little trivia!
