Funny, how the Fox 5 video showed the radio on the county deputies belt....an XTS series Motorola radio! If I'm not mistaken can't they be programmed to operate digital too, even P25? All it would take is a flash of the radio and poof, the deputy on the analog system can press a button and talk on an Atlanta group.
Second, Atlanta's P25 system allowed for "patching," like when Atlanta PD/FD was on both their analog and new digital system before ATL went full-blown digital. Why can't they open up a patched talk group so the analog guys can chat with the digital guys? They did it a couple months ago!
Oh, but wait, I get it. They have to spend tens of millions of dollars first!
Brilliant!
