Three North American LF signals received in UK

Jim Moritz, M0BMU, in Hertfordshire, England, recently was able to receive LF signals transmitted by three North American stations operating on 2200 meters - in the vicinity of 137 kHz (137.777 kHz).

Copied using a computer equipped with ARGO software were the "QRSS120" very slow-speed CW signals from WD2XES, operated by John Andrews, W1TAG, in Massachusetts; Joe Craig, VO1NA, near St Johns, Newfoundland; and WD2XDW, operated by Laurence Howell, KL1X/5, in Oklahoma.

Moritz received the trio of signals October 29 at approximately 0300 UTC, reports Craig, who notes that Howell's LF CW signals also were detected recently in New Zealand. "The CW speed is very slow, taking two minutes to send a dit," Craig explained. "This corresponds to a speed of 0.01 WPM."
