Some better images from Honolulu

Yesterday evening I tried again on 11088 kHz and luckily the reception was a bit better! Now you can see a "real" map!

Unfortunately the test transmission is a short white chart with a black horizontal line...

That's better, isn't it? Compare it with the original:


I received two more complete charts until I quit due to excess noise but I think it's unnecessary to upload them now I have at least one good image from them. I'm happy I'm back to HF-FAX DXing, after a long time.

QUESTION: Does anyone of you know if they answer to QSL reports? Any ideas for how to send a proper QSL report? So far I got response only from amateurs, so far no response to a letter sent to Northwood and an e-mail sent to Hamburg...

And yes... Honolulu!

Propagationally speaking, Honolulu is more difficult than Wellington, New Zealand, even if it is closer (13700 km instead of 17400 km).

Yesterday, I had some luck with Honolulu!!! The frequency was 11088.1 kHz USB, starting at ~1723z till ~1834z.

Here is a comparison of my received images to the ones actually sent. Mine are the top (and noisy) ones:

Despite the noise, I think there is some resemblance with the original images. These are provided by NOAA and I was lucky to find the originals today since they keep only the latest images! I've got Honolulu! What do you think?
