I would be very careful of transmitting on the same frequency as WWVB. It is very likely illegal.

That’s a very good point but the transmission power is extremely weak and won’t propagate more than 1m.

Quite possibly, however the range is stated in centimetres so practically it’s unlikely to be a concern.
