Steve, the percentage of the confirmed QSOs should be much higher, probably closer to 50%.

In my experience, Steve should not expect an overall 50% confirmation on a log going back 18 years.

Since being licensed in January 1990, I have logged 24,538 QSOs in CW, Phone, RTTY, PSK, Pactor, and FT8. My overall LoTW confirmation rate is 27%. Dividing my log into three 9-year intervals and determining the LoTW confirmation rate for each interval reveals that confirmation rate is inversely proportional to age:

1990-1999: 11%

1999-2008: 28%

2008-2017: 48%

Steve's overall 33% confirmation rate for QSOs made since 2001 is consistent with this pattern.


There is another factor: digital mode ops are more likely to QSL via LoTW because they are more likely to use a computer for logging; from my entire log:

Phone: 19%

CW: 27%

Digital: 37%

Thus the higher the percentage of digital mode QSOs you've logged, the higher your LoTW confirmation rate will likely be.


Slicing and dicing the digital modes shows both of these factors at work:

Pactor: 0%

PSK: 33%

RTTY: 38%

FT8: 74%

All FT8 QSOs were made since July, so their confirmation rate is driven by both their recency and their high probability of computer logging.

from: Uses LOTW? No
to: Uses LOTW? Yes

How about to Uses LOTW? Yes yes, five hundred thousand times yes!

And Clublog too. Below shows very-good-but-not-quite-perfect cross-reference match both ways on Clublog:



Thanks for all the Q's, Steve!

@N3QE,
hi my good CW  and contest friend…
Yes LOTW was easy for me because of using Clublog before I only had to push one button and all my QSOs were exported from Clublog to LOTW. great.
Sorry for our missing QSOs I think its me having the bad ears…

Steve, the percentage of the confirmed QSOs should be much higher, probably closer to 50%. I wonder if some of your logs may be in your local time instead of UTC.

If his logs go back to 2001, his match rate should not be so high.  LOTW was insignificant until 2004 and took a while to ramp up, too.  A lot of folks have not bothered to go back to QSO number one (those may be on paper or otherwise hard to access) and in their individual cases, decided to upload from whatever date they registered.
