It could be that the ambient noise floor is getting into the rcvr..
Are there any AM stations around that can be picked up in your area? If so, See if the interference that your hearing is with this station also. If this is the case, It’s going to take a very strong signal to override the noise..
Have you made a test outside of the campus area.. Maybe 1/4 mi. away from the buildings? If it is set up correctly, You should be able to hear it that far away. This takes you away from all of the noise generated within the buildings. Or, take a portable radio with you and test right at the xmtr location. It may sound a little “Fuzzy” from overdriving the receiver but the noise should not be there unless it’s getting into your audio chain..
Changing frequency may help. The only way to know is to try..
