Which may simply mean nobody else has found and reported the transmission >> Those sites are (very) informative, but not authoritative as they rely upon (sometimes uncorroborated) input from all of us (some far more than most).
Also, a scan will not always report either the exact same frequency and symbol rate when repeated, nor will scans necessarily report a perfect match with any listed data (Where it exists).
So, an SR of 3743 is the same as one of 3744 in the context of what you are doing, and a frequency of 11517 is the same as 11518 too.
You are almost certainly picking up the exact same 15W transmission at strengths and quality that depend upon how far your dish is displaced from 15W. You detect something apparently from 16.2W and 18W respectively entirely because of the beamwidth of your dish. A bigger dish will not be so prone to this as the beamwidth decreases with size.
All you've done is pick up a hitherto unlisted (on the sites you referred to) transmission and led yourself up the garden path and the confusion is of your own (well-intentioned!) making.
