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.
