  • Multi-waveform capability
  • Selective links in one net
  • User-friendly HMI (single-knob control for basic operation)

Brief description

The R&S®M3TR software defined radio family is a generation of high-performance digital radios. The lightweight R&S®MR300xH/R&S®MR300xU manpack radio offering solutions for all aspects of tactical communications as well as uniform and reduced interservice logistics forms the heart of the integrated communications system. A lightweight handheld version (R&S®MR3000P) supplements the radio family. As with the manpack radios, the R&S®MR3000P supports both open and secure communications modes.

Features & benefits

Voice communications

Analog voice

  • Analog voice - the following signal modulations are available:
    • J3E (USB, LSB)
    • A3E (AM)
    • H3E (AM)
    • F3E (FM)
  • Squelch - the following squelch types are supported:
    • Received signal strength indication (RSSI)
    • 150 Hz tone squelch
    • Signal squelch (CTCSS selective calling)
    • Syllabic squelch (digital recognition of voice components in signal)

Voice communications

Digital voice

  • For communications using the EPM (ECCM) methods R&S®SECOM-V, R&S®SECOM-H, R&S®SECOM-P and R&S®SECOS 5/16 TDMA, voice is digitally transmitted 
  • Secure voice enables encrypted connections in FF channels or together with ALE-3G
  • VoIP, SIP and phone patch: Voice over IP, especially with SIP and RTP protocols is the standard in many professional communications networks
  • Last ditch voice ensures that recipients receive voice messages in almost all circumstances

Data communications

  • HF wideband, MIL-STD-188-110C App. D
  • R&S®SECOS 5/16 TDMA
  • R&S®SECOM-V data mode
  • 72000 bit/s VHF/UHF modem
  • R&S®IPoA – IP radio transmission
  • R&S®IPoA message service
    • Alarm messages
    • Short data messages

EPM (ECCM) waveforms

  • R&S®SECOM-V - optimized for tactical communications and operates in the full VHF/UHF band
  • R&S®SECOM-H - a Rohde & Schwarz proprietary frequency hopping HF radiocommunications waveform
  • R&S®SECOS 5/16 TDMA - air-ground-air waveforms for interoperability in EPM (ECCM) mode between R&S®M3TR and R&S®M3AR and R&S®M3SR radios
  • HAVE QUICK II - the NATO ground-air-ground waveform HAVE QUICK II provides interoperability in EPM (ECCM) mode between the R&S®M3TR, R&S®M3AR, R&S®M3SR radios

Logistics and readiness

  • Low volume and weight
  • Built-in test down to module level
  • Common logistics concept for reduced costs throughout lifecycle
  • Common human-machine interface (R&S®MR300xH/R&S®MR300xU)
  • Automatic firmware update of external components
  • Synthesizer calibration via antenna connector
  • Minimal training required
  • Excellent flexibility
  • High MTBF
  • Low volume and weight
  • Power-saving mode
