Anyone???

Hello Everyone:

Have an issue with my XTL, that I was hoping someone could help me out with before I have to resort to sending it to the Depot and spending an outrageous amount of money. As I mentioned, I have an XTL500, O3 Control Head, Mid Power, UHF-2 Band. The radio has been in my truck and ...

So basically, I am "SOL" if I want to use the O3? It would have two be two of the same of two of either the O2, O5 or O7 heads in any combination.

Is it possible to run two different control heads off of a single APX7500 chassis? I'd like to run a O3 up front and an O5 in the back of a 2015 Tahoe for a Fire Department.

Thanks,
Nick
