Honolulu FAX audible on 16 MHz

Unfortunately I haven't got a decent map from Honolulu HF-FAX service on 16133.10 kHz USB, but I can hear it right now (1830z). My ears can detect the presence of fax signal but the software decoder just gives a very noisy printout.

I managed to log Honolulu on 16133.10 kHz USB this morning at 0715z, and also on 11088.10 kHz but still no clear image reception... While the HF conditions gizmo in my blog says Poor, I wonder if these... 11(!) sunspots makes the difference!
