Yep Mike, I well remember that modulated CW. However, there were many times, when I was growing up in Nebraska, that I could copy the CW part when the A M audio just wasn't strong enough to hear. Of course, in those days, they sent every five minutes instead of every minute. Talk about dedication to WWV. I had a friend, when we were at the school for the blind, who literally stayed up all night once and listened to WWV for eight hours straight. When I asked him why he did it, he said, I just wanted to hear what it was like at night. Phil k0ns
