A nice HF-Fax picture from Tokyo

Last night I decided to give a try to JMH HF-Fax service. I only got this nice picture at 1930 UTC on the highest (13988 kHz) JMH frequency:

13988.5 kHz, 1930z
24HR SURFACE PRESSURE, WIND, FOG, ICING, SEA ICE PROG

The following transmissions were noisy so 1930z sets a limit for the reception on 14 MHz from Japan to my Location.

JMH new frequencies confirmed

It seems that the image I posted earlier from JMH Tokyo HF-Fax Service was the best so far... I have trouble getting a decent image from Japan. The good news? I confirmed all three frequencies (2 new, one old) of JMH. Here is the broadcast schedule, effective 1 March 2007 (source JMA).

JMH Japan HF-Fax service frequencies

The latest HF-Fax frequencies for JMH Japan HF-Fax service are:

3622.5 kHz
7795.0 kHz
13988.5 kHz

(all H24, 120/576)
Myself have logged 7795 and 13988.5 kHz. Here is today's test transmission at 1300z:
There is some QRM from a digital station few Hz lower. That caused my decoder to choose 60 LPM instead of 120 so I cropped the resulting image.

JJC Kyodo News Agency, Japan, HF-Fax

How a newspaper looks like if faxed through shortwave? My receiver gives an answer!


12746 kHz 1200z

That's how it looks like! Kyodo News provides weather, news & sports in Japanese & English via HF-Fax. Probably it is the only HF-Fax station which provides such info.

One thing to note, the service uses 60 RPM, in contrast to 120 RPM which is more common. Here and here (hi Chris!) you can read more about HF-Fax reception instructions and jargon.

Additional info can be found in Wikipedia's entry about Radiofax.
