Guest Post by Robert Gulley K4PKM<\/p>\n

I wanted to pass along three useful references I came across from several posts in the Utility DXers Forum<\/a> posted by Steve Handler.<\/p>\n

The first is:<\/p>\n

“Radio Aids to Marine Navigation 2025 (Atlantic, St. Lawrence, Great Lakes, Lake Winnipeg, Arctic and Pacific<\/a>”<\/p>\n

(Both English and French versions are available, published by the Canadian Coast Guard)<\/p>\n

The second is:<\/p>\n

WORLDWIDE MARINE RADIOFACSIMILE BROADCAST SCHEDULES<\/a> published by the U.S. DEPARTMENT OF COMMERCE\u00a0 (WEFAX Weather Broadcasts, March 2025 edition)<\/p>\n

The Third is:<\/p>\n

US DOD \/ National Geospatial Agency Flight Information Handbook<\/a>\u00a0 (March 2018, 273 pages) containing frequencies and other interesting info<\/p><\/blockquote>\n

I suspect many SWLing readers are also on the Utility DXers Forum, but for those who may not be, or who might have missed these posts, I hope you find them useful!<\/p>\n
