The Canadian Station, CFH, runs at 100 wpm, 74.2 baud,
850 HZ shift.

"CANADIAN FORCES METOC CENTER, HALIFAX, NOVA SCOTIA, CANADA"

The frequencies are:

4271, 6496, 10536 and 13510 KHZ.
They are also on 122.5 KHZ, but I've never been able to hear them
there.
The 10536 channel is active 24 hours a day. The others are
more sporadic. I have copied this station from both sides
of the country.

CFH sends the weather reports for most of the larger airports
on the Eastern Seaboard. While the reports are coded, the coding
"key" can be found on the NOAA website, with some poking
around. The code is called "METAR". With a little practice you
can "read" the reports. Anyone who is an aircraft pilot would
immediately recognize the reports. CFH also sends plain text forecasts
for the Nova Scotia area. At times, they send the iceberg
reports (interesting to read). The FAX transmission are comprised
of weather maps for the North Atlantic area. I copy them using
a little AEA FAX gadget that plugs into the COM port and
uses simple software. It's got to be more than 10 years old now.

I have always been curious as to who CFH sends the weather to. I
have assumed it was ships at sea.

Most other RTTY stations that I have found send very little information;
most
of their transmissions are just identifiers.

Don't forget the ARRL bulletins. They're sent every weeknight around
6 or 7 PM (depending on whether or not it's daylight savings time).
They send at 60 wpm, 170 HZ shift and also sometimes on ASCII.
