I am formerly of Reading, but am now elsewhere. Given that I occasionally try to observe some of the changes in my former home. Basically I haven't seen much at all lately, except some notes to say that some of the analog talkgroups for pd fd and ems were also simulcasted as digital talkgroups. Usually when this is done it's during the a changeover period to digital while not all of the radios are changed. I also heard some chatter regarding encryption of the EMS traffic.
Again, just passing on what I have heard. You might want to send a private message to the last few that have made changes to the Reading trunked system on this site to see if they can help.
A BC780 will pick up the analog trunked with no problem, but if you are considering purchasing one, I would want an answer to the digital question.
