Chile HF-Fax service log

And here is a HF-Fax log!

This is the schedule transmission logged from Chile CBV HF-Fax service, logged on 29 July 2155UTC, on 17144.59 USB:

171446.4 kHz 2155z

Many thanks to Nairam for providing the tip! He had better reception than mine as you can check his images here (schedule) and here (+36h prognosis). The transmission ended before the completion of the full schedule image.

73!

Emission for syntony Valparaiso Playa Ancha Radio CBV

A better "tuning aid chart" received today. While this is better than the previous one, still needed image processing (slant fix) and it's not complete. It is obvious I got the final part of the transmitted "chart".

8678 kHz, 2247z

The following transmissions were noisy so I didn't uploaded any of them. Again it is a stormy day, we had 2 X-ray flares within 20 hours.


3-day Solar-Geophysical Forecast issued Dec 14 at 22:00UTC

Solar Activity Forecast: Solar activity is expected to be moderate to high. Isolated X-class flares from Region 930 remains a possibility.

Geophysical Activity Forecast: The geomagnetic field is expected to range from active to major storm levels for 15 December. This activity is due to the CME observed on 13 December. Unsettled to active conditions are expected for 16 and 17 December.


That's not a promising forecast... It really discourages me from hunting other HF-Fax transmission from distant places... But right now I have Louisiana... Stay tuned...

New images from downbelow

Here are more images from CBV Valparaiso, Chile HF-Fax service. The quality is not stunning but remember, these traveled 13500 km under stormy weather! (Another X-ray flare occurred today, magnitude X3.4).

The frequency was 8677 kHz (-1.9 kHz if you use USB, as myself) and the time was 2210-2341z



8677 kHz, 2220z and 2241z



8677 kHz, 2310z and 2331z

The last one obviously is a sat image. The fact that the third picture is the best is in par with VOACAP's prediction of maximum SNR at 2300z. Impressing!

CBV Valparaiso Chile Meteo HF-Fax

This evening I decided to hunt for other Fax transmissions. I got Seoul and Chile! I tuned to 8677kHz at 2308z just in time to let the station introduces itself! Lucky me!

8677 kHz 2308z

The original decoded image was slanted, but I did my magic by simple image processing! Distance from me is about 12500 km. The farthest HF-Fax image I have! That's real DX!
