Cape Navel today and... yesterday

The ionosphere is disturbed again, but reception on 18238 kHz today at around (!) 1530z was the best I ever had! The transmission started early at 1523z, and was a "blurred" Surface Analysis chart.

18238 kHz, 1523z 12:00 Surface Analysis


But yesterday... a series of false starts:
  • 1538z: Transmission of a "blurred" Surface Analysis starts.
  • 1549z: Stops! Starts again!
  • 1552z: Starts again! Ends!
  • 1553z: New trial: Header only!
  • 1555z: New attempt, this one finishes normally at 1616z!

NMG New Orleans on higher frequency

I managed to log New Orleans on its highest frequency, 17146 kHz this afternoon. Here are three pictures:

17146 kHz, 1335z HIGH WIND/WAVES

17146 kHz 1350z 72 HR WAVE PERIOD/SWELL DIRECTION

17146 kHz, 1400z GOES IR TROPICAL SATELLITE IMAGE

ZSJ Cape Naval again

18 MHz was quieter this morning, but instead of a typical weather chart, I got this one:

18238 kHz, 1033z

Yes, It's only that. I have rotated the image. Also, some image editing magic to correct my decoder's fault of missing sync and adding the final part of the transmission. If you compare the header with my previous images, it's obvious that conditions were better. Cape Naval notoriously continues to transmit early or late, even only the header for a couple of times before transmitting a chart. At least some moments later got some charts:

18238 kHz, 1102z

18238 kHz, 1124z

Conditions stayed good in the afternoon; a "blurred" chart this time:

18238 kHz, 1532z


I like this station because it's so unpredictable. I can't wait sunspot number rise and have even better signals on 18 MHz! I like higher frequencies; they give cleaner and steadier HF-Fax images!

E25 different voice

A different announcer appeared today with the "control" message "830 11 12" at 1215z. His first (probably) performance was back on 10/11/2006. Check Ary's webpage for that sample. Listen here today's recording.

First E25 message for 2007

A short message in Arabic was the first one for 2007. Maybe this is their way to wish us happy new year. The translation was easy, since only 2 unique groups existed:

  • E25 9450 AM 1213z: Carrier, music intro, then OM calling "835 830 10" meaning "message for 835 only". Very good to excellent signal; low modulation. The message was:
7050/7050
5555/5555
5555/5555
5555/5555
5555/5555

Easy to translate. But of course maybe I did a mistake. Here is the whole transmission recording. Nice piece for learning Arabic numbers. So far I have learned sifr (0), khamsa (5), itnien (2), wahid (1) (I confuse itnien as 1 sometimes).

New Orleans HF-Fax schedule

The "Request for comments/Broadcast Schedule" chart from New Orleans HF-Fax service, as of 05/01:

12790 kHz, 2025z NMG New Orleans, Request for comments/Broadcast Schedule.

All-in-one plus QSL info! I hope the address is still valid!

Ice

I'll present you some HF-Fax images regarding ice & icebergs, which I received yesterday (Friday 05/01) from Hamburg HF-Fax service, and Boston. Here is the one I like most:

9110 kHz, 1810z, NMF Boston, Ice Chart.

I like the "CQ" in the beginning and the comment "The 2007 ice season has not opened"! DXers overlook the powerhouses but they can also send interesting charts like the following, instead of "surface analysis" and charts full of isobar lines!

7880 kHz, 2100z, DDK3 Hamburg/Pinneberg, Ice Conditions Chart Northwest Atlantic. (image rotated 180°)

7880 kHz, 2115z, DDK3 Hamburg/Pinneberg, Ice Conditions Chart West Baltic Sea.

By overlooking the "common" ones (Northwood & Hamburg) I have never logged the above chart, which is also beautiful!
