Warren, I recall copying Dex's 137 kHz signal a number of times in daylight. But those were QRSS60 transmissions. Think I could detect his signal at QRSS3 sometimes but this morning's signal at 74 kHz was better than that. Of course with a sample size of one conclusions can't yet be made. -- 73, Garry, K3SIW, EN52ta, Elgin, IL
