It does indeed broadcast radioteletype and facsimile weather reports and forecasts on a number of HF frequencies. For those interested, I have appended some frequency information and a FAX schedule (perhaps out of date). At least here in New England, the CFH signals are quite strong and easily received. ------ CFH Radioteletype frequencies (some part-time): 75-baud radioteletype, 850-Hz shift: 4271, 6330, 6338, & 10536 kHz FEC radioteletype: 13351 kHz ------ Forwarded from rec.radio.shortwave: From: roskos@IDA.ORG (Eric Roskos) Subject: New CFH Fax Schedule Date: 29 Jan 90 00:50:20 GMT Organization: IDA, Alexandria, VA A few mornings ago I happened to be up at 5AM when CFH sends its Fax schedule, and thus recorded the current schedule. According to a note at the bottom, this is a new schedule as of 1/15/90, so here is the current schedule. (This was sent via Fax and is hand-transcribed below, so any errors are probably mine.) Note that while some of these charts are local to Nova Scotia in their coverage, others, such as the surface analysis, cover the entire east coast of the US. The Surface Analysis is the old-fashioned hand-drawn kind with the graphical symbols, rather than the digitally-produced NOAA kind with the nearly (if not entirely) illegible small numbers -- it's especially good if you're using a PK232 or other low-resolution device, since the large lines and lettering make it easy to read by comparsion to the NOAA charts.
