Rocky Talkies work with BCA radios, as well as other brands and options like Motorola, and other FRS radios. You will need to use a specific set of channels to interface, set privacy codes, and work with BCA radios. However, the manual for the Rocky Talkie walks through how to do this in detail for each kind of radio. This is a great feature as you can use your Rocky Talkie to communicate with friends who already have a different brand of two-way radio. There’s no need to replace them all.
