Radios

Preferred Models

  1. Commercial two-way radios are used exclusively for our feeds, as they provide superior reception & audio quality over scanners or SDRs.
  2. Our standard radio hardware consists of one of two models:
    • Kenwood TK-7180 (Analog only)
    • Kenwood NX-700 (Analog & NXDN Digital)
  3. Other commercial radios (such as Motorola) may be used as long as they perform well & utilize line level audio, not the speaker jack.
    • The service manual will show how to tap into line level audio for your specific radio.

Kenwood Notes

  • Audio is tapped from the radio via the rear DB25 port using pins 17 (RX Filtered Audio Output) and 18 (Ground).
    • Do not use the speaker jack. The DB25 port provides superior audio quality.
    • Prebuilt audio cables for the TK-7180/NX-700 can be purchased on eBay at the following link:
    • Alternatively, you may assemble your own cable using a DB25 connector and a 3.5mm audio jack.
