The unofficial story is that there was a well-off listener to WGBH-FM who lived on the back side of Beacon Hill and couldn't reliably get the 89.7FM signal. He/she complained about it to the engineering department, they explained the problem, he/she offered a lot of money if they could find a solution, and viola! That's how 96.3 came to be. It's actually not uncommon.
This well-heeled individual was supposedly getting "multipath distortion" because Beacon Hill was blocking the primary WGBH signal from Blue Hill, and there were reflections of it from surrounding buildings, etc... WGBH pays MIT college station WMBR some rent for the tower space for the repeater, so as they say, "everybody wins".
I have a friend who lived on the back side (north face) of Beacon Hill, and without cable, it was impossible to watch any of the Boston TV stations which transmit from 128 Newton/Needham. Over a regular rabbit-ear antenna, each channel appeared as hundreds of superimposed "ghosts". New Hampshire stations came in very well, though. Channel 11 (PBS) from Durham was like a local.

I do kinda wish 96.3 would go away...it'd be a nice frequency for WRBB to be on.
I don't think that would be permitted. 96.3 was not originally a frequency that was considered open or available for anything in the area due to third-adjacent 96.9 Boston (and perhaps first-adjacent WSRS 96.1 Worcester). WGBH was originally first authorized to put the repeater on 97.7, but complaints from the old co-channel WCAV Brockton forced them off that frequency after a short time, and they had to explore other options.
I understand that the repeater was only allowed to go on 96.3 pending agreement from Greater Media due to their third-adjacent 96.9. The agreement was approved for 96.3, but only for the WGBH repeater which transmits with just five watts in a highly directional easterly pattern aimed at Beacon Hill. In other directions, it can't be heard clearly beyond a mile or so in East Cambridge, and directly across the Charles River in the immediate Back Bay. (I do barely get it two miles away here in Somerville, but very weak and noisy).
The directional five-watt WGBH repeater doesn't even cover clearly (if at all) at Northeastern University, where WRBB is located. WRBB would want, and have, to put more power and a modified pattern on 96.3 than that of the current WGBH repeater. Even ten watts non-directional would be a significant increase over what's currently there, and I don't know if either the FCC or Greater Media would agree to that on a frequency that was not even originally considered available.
