Not many agencies even use BP due to it's extremely weak nature. If you have a need to listen to BP just buy a Moto radio or an ADCR25 board.

Just an example, but we can see a mixture of BP and other enc mode. If you can use, for example, TYT md380 how can you start to try to do a work? I have to underline that sometimes there is no possibilities to obtain the things you mentioned in your post.
Thanks for your time
