Radio Programming Options

The following does not apply to FRS, MURS, GMRS, LTE, Satellite, or IP radios.

Most business radios aren't ready to use out-of-the-box. So radio programming is needed to set the frequencies in the radio. For some radios the frequencies can be set through a menu interface. While other radios must be programmed using a PC, radio software, and a cable to connect the radios.

Here are your programming options:

  1. We can program your radios - with radio orders 
    • We provide basic radio programming for radios ordered through us. See the description below of basic radio programming.
    • Email us your Frequencies & Call Sign - the FCC requires dealers to verify your license before we program.
    • Please allow 1-2 days for first-time setup of radio programming.
    • Due to staffing limitations, we are not able to program radios purchased from other dealers.
  2. Match to your Previous Order
    • If you've ordered from us before we have your information stored.
  3. You can program the radio(s)
    • Connect Systems (all models): You can purchase software and cables from us. 
    • Kenwood ProTalk Business Radios (NX-P1300/NX-P1200 series, TK series, PKT)
      • Have pre-stored frequencies and you can easily program these radios through the radio's menu interface.
      • Custom frequencies will require dealer programming.
    • Icom (all models): Icom no longer allows dealers to sell software and cables over the internet. You may call us to discuss your options.
    • Motorola Business Radios (models beginning with CLP. CLS, RM, RD):
      • Have pre-stored business frequencies (Part 90). Software to program these radios is available on the Motorola website.
      • Just go to the product page on Motorola's website and you can download it for free. We can sell you the cable.
      • Custom frequencies will require dealer programming.
    • Motorola Commercial Radios (models beginning with CP, CM, MagOne):
      • Software to program these can be purchased directly from Motorola. We can sell you the cable.
    • Vertex Standard Radios:  You can purchase software and cables from us. (some cables have been discontinued)
  4. If you don't have a FCC license we can help you apply for one.
    • These licenses are for businesses, non-profit organizations, local and state government agencies.
    • We do all the work! Give us a call at 855-289-2929.
