Flawless FDMA Fidelity.

Optimized for line-of-sight propagation over vast distances, the VR-P25V Series utilizes an integrated high-linearity RF design to amplify 136-174MHz frequencies. It preserves the delicate frequency modulation profiles of both P25 Phase 1 (FDMA) and high-grade Analog FM / Marine bands with absolute zero audio clipping or data packet loss.

📢 Comprehensive Interoperability Matrix (Who Can Use This?)

1. Supported Digital FDMA Protocols & Systems:

  • P25 Phase 1 (C4FM): Seamlessly compatible with VHF public safety radios (Motorola APX/XTS series, Kenwood NEXEDGE P25, Harris VHF).
  • NXDN / IDAS / dPMR: Fully boosts Kenwood NEXEDGE and ICOM IDAS digital VHF business radio networks.

2. Supported Conventional Analog & FM Systems:

  • VHF Amateur Ham Radio: Works with all conventional analog 2-meter hams and business band portables (Baofeng, Yaesu, Icom, Kenwood, Quansheng VHF editions).
  • Marine & Wildlife Fleets: Perfect for high-power VHF marine radio conversions used in coastal tracking, search and rescue (SAR), and open-field off-road routing.

⚠️ SYSTEM NOTE: This unit is strictly optimized for FDMA & Analog architecture. It does NOT support TDMA protocols (such as DMR Tier II or P25 Phase 2).
