That should certainly put you well inside WBAL's primary protected contour. I calculated the field strength of WTAM's lower primary digital sideband (i.e., the noise signal under WBAL) to be 0.42 mV/m. This is the 10% skywave value, which means the field strength would be exceed that value 10% of the time. That value would be 27 dB less than WBAL, which would certainly make the noise audible. It would be much worse closer to WBAL's NIF contour, however, which should be a cause for concern for them.
