For the past week+ there has been some on-off keying intruder on the 40M CW band easily heard on both coasts of North America. It is occasionally QSY'ing anywhere from 7.04MHz to 7.07MHz and may be outside that range goo. It is often on a whole multiple of 500Hz. Although we are most often hearing one CW frequency with our rigs set at a normal bandwidth, I can often find an "evil twin" which is key-down while the other one is key-up, so I think it's more likely to be super-wide shift FSK. Below for example is me putting receiver 1 on 7.063MHz and the other on 7.070MHz circa 0400Z on Jan 30 2026. You see when one is key up the other is key down. The basic signal rate seems to 0.05seconds (20 Baud). Our CW-seeking brains seem to try to interpret it as CW because if we here one element at 0.05seconds we think it's a dit and another at 0.15 seconds our brains. I do not recognize 7kHz 20 baud FSK as a standard encoding anywhere but someone might know better than me. I'm gonna record some longer patches and see if I can recognize any framing.

Minster got his Novice license, WB2MAE, in 1977, when he was in his teens. He progressed from Advanced to Amateur Extra and, after a stint as W2D, he settled on the vanity call sign NA2AA in the 1990s to honor a mentor, N2AA, and the contest station he used to frequent, K2GL, in Tuxedo Park, New York. Minster’s ham radio pursuits have ranged far and wide over the years. His background includes National Traffic System training and participation in public service events, as well as contesting from home, club stations, and contest stations in the Caribbean — particularly on Bonaire, where he is a member of PJ4G. Primarily a CW operator, Minster collects unique and vintage bugs and keys. In addition to being an ARRL member, Minster is a member of AMSAT, the Frankford Radio Club, the Straight Key Century Club, CWops, and the North American QRP CW Club. “I spend every day of my life, one way or another, engaged in amateur radio. It is more than just a hobby for me; it is my community. It is where I live; where I have built lifelong friendships, and friendships that span the globe. Amateur radio allows me to dream and to experiment. I can’t wait to bring my energy and boundless enthusiasm in service to ARRL.” Minster earned a bachelor’s degree in computer engineering from The Ohio State University and has a special interest in satellites, digital communications, remote operation, and ham radio computing and software. He has written keyer software for the commercial market, and contest logging, packet, and satellite telemetry software for personal use.

Remember that lighting arresters will not protect your shack in the event of a direct strike! Best practice is to disconnect all antenna feed lines when lighting is active in your area. 73 & stay safe!
