I pulled these additional Charlotte broadcast frequencies up from the FCC database, I dont know if they are used for the related newstations choppers but you can try them out.
WSOC: 450.0125 MHz 450.4875 MHz 455.4875 MHz
KXEL: 450.65 MHz 455.05 MHz 455.15 MHz 455.25 MHz 455.65 MHz
Jackson Telecasters: 450.2125 MHz
North Carolina Broadcasting: 450.6125 MHz 455.6125 MHz
Also the following site is awsome.
AirNav: Airport Information
On the homepage click on advanced search then enter KCLT in the airport identifier box in section 1, then click off airports & click on heliports in section 2 then in airfield use click on private, public & military airfields then choose between 20 to 200 nautical miles in the 2nd. dropdown menu in section 3 then hit search, when the heliport list comes up just click on the left side blue helicopter icon to display all the heliports info.
Have fun.
