Packer Talk Radio is a bunch of bloggers and Twitter people, but unsure if they post reports or just do a podcast talking to each other. http://www.blogtalkradio.com/packerstalk
In podcast form: http://packerstalk.com/category/podcasts/

These guys are on a few radio stations and the host is pretty legit. He looks at things from a standard analyst mode, but isn't too much of a homer and has decent guests. But I am not sure how much they do the Packers in training camp. They might do significant coverage because the Packers were still getting airplay in the Spring after the draft, but you will have to try them to find out. Not too newsy though, so you may have to check elsewhere for details. http://www.cheeseheadtalk.com
Also call themselves Talking Cheeseheads, but they are losing the Google battle over that name to the Packers Talk Radio link above.
