I haven't had a problem with the WWV tones. I first zero on WWV, then wait for the announcement that takes place at the end of every minute. While the announcers are giving the id and time, I check to be sure I am zero with the carrier (move REF OSC off frequency and make sure the beat reappears). There's plenty of time to do that during the announcement period. Even I need a bit longer, there's another announcement period 45 seconds later to check again. Of course, virtually ANY AM broadcast station will be on frequency too. After setting up on a BC band AM station, you can double check your zero beat on WWV if you like. Remember, you have to be a full 400 or 600 Hz off frequency before you're in danger of zero beating with the WWV tones by accident and, typically, you'll be within 1 or 2 Hz after zero beating to any AM station.
