What area are you referring to? I hope to be able to monitor Phoenix FD wherever I can.
Most of Tempe PD's talkgroups are encrypted, with a few in the clear according to the database.
A is Phoenix PD.
B is Phoenix FD.
C is Chandler/Sun Lakes/Maricopa PD & FD. (Sun Lakes is MCSO.)
F is Tempe. (FD may or may not be carried on F.)
H is Scottsdale PD & FD.
That area.
For the most part, you'll probably be within range of B through that area. Unless you go too far east, into Mesa or Gilbert, then you may be best served by Simulcast C.
You may or may not always hear K6 or K9 on C/F/H, as I don't always hear K7 or K8 on Simulcast G here in the West Valley. (At least there's been instances in the past when this has occured for me.) The same goes for K10/11/12 for major incidents in the West Valley, if you're listening to C/F/H. They may not always be carried on C/F/H.
I forgot. Phoenix PD South Mountain precinct may be able to be heard on Simulcast C, as well as Simulcast A, of course.
