I'm probably too late to be of use, but just for reference I'm hearing a lot of chatter tonight for SPD South (TGID:3312), East (TGID:3344) and West (TGID:3248) on at least KC Valcom 1 (851.8125).
Nothing in the past 20min for SPD North (TGID:2380), but maybe that's just slow......oh, ha. A little dyslexic there. North should be 3280.
Well, your post at least helped me find an error
