Common buying questions
What replaces an RDX fleet?
Start with CP100d, then confirm band, analog settings, interface and accessories with our team. Existing accessories do not necessarily transfer to the new radio.
Can these radios work with my existing radios?
Share your current model numbers and channel settings before ordering. Matching the series name or channel number alone does not establish compatibility; the frequency band, operating mode and programmed settings must also match.
Is programming included?
Radio programming is available at no charge. Tell us which existing radios and channel settings you need to match, and request programming when ordering. Programming cannot add unsupported hardware or system features.
