Record Surface Noise Question

On records with even a mild noisy surface, I'm hearing it only in the right channel for more than the first half of the record and then pretty balanced when it gets past the middle through the end. Is this an alignment issue? I've tried to adjust anti-skate (I can do it on the fly) and it doesn't affect this at all. It happens on new or new-to-me used or old records that I've had forever. Everything. Arm is a Moerch UP4 and I use the MintLP protractor.
