My recollection is that harmonics must be down 40 dB from the carrier. That's .1 Watt for WCTC. You didn't say how strong a signal you are receiving - if it's very strong it's surely more than .1 Watt and deserves a mention. If it's a wispy DX level signal, they may be within legal limits and wouldn't appreciate a false alarm.
If the 40 dB rule has changed since I last had to know these things, I'm sure one of our broadcast engineers will speak up right away.
