It appares based on this article posted by Macro Consulting that Boston Police will be upgrading their exsisting radio system to P25.
This project seems to be in its very early stages, so you should not have to change anything to listen to BPD in the immediate future, however if you are interested in monitoring the Boston Police in the future you may want to start saving up for a digital scanner.
It appares that after the upgrade they will remain UHF conventional on the same frequencies just in P25 digital mode, however there is little infomation avaible at this point in time. There is a therad over at Scan New England discussing this upgrade.
