500 kHz Distance Record Set

On January 17, Neil Schwanitz, V73NS/WD8CRT, on Roi-Namur in the Marshall Islands, received a signal from experimental station WD2XSH/20. This experimental station, operated by Rudy Severns N6LF, is located in Cottage Grove, Oregon — 4737 miles away from the island in the Kwajalein atoll. The 13 words-per-minute CW transmission was copyable by ear and also appeared in the Spectran capture; “SL” in the capture is from a non-directional beacon on 505 kHz located in Khomotovo, Russia.
