[SFDXA] K4FK LoTW QSL milestone reached

 From the LOTW front page:

521,597,990    QSO records have been entered into the system.
75,601,748    QSL records have resulted. [that is, QSO record matches, = 2 QSLs 
per match]

LOTW average is 2x75,601,748/521,597,990 = 0.29 or 29%   ... that's on the basis 
of more than half a billion QSOs!
The actual error free rate is higher - there are a lot of errors uploaded.

73,
Kai

It's also true that RTTY QSOs in general tend to have a higher LoTW rate, I think because RTTY operation these days is computer-centric and nearly all RTTY operators have electronic logs.  The lowest HF LoTW QSL rate by mode, in my experience, is SSB, for I think a similar reason -- there is a positive correlation between electronic logging and LoTW participation, and SSB operation does not require a computer.
