    4

    Dedicated Companion App

    Connect via USB-C OTG cable to Android/iOS Streamline apps to unlock stereo audio, visual images, text broadcasts, recording, and offline E-Learning.

    Getting started

    How the N88 works

    1

    Tune any band

    Receive MW, Shortwave (3–30 MHz) and VHF (87–108 MHz) in AM, FM or DRM. Use auto-scan, raster tuning or direct manual frequency entry, and save favourites to 4 physical preset buttons.

    2

    Connect the companion app

    Plug the N88 into an Android or iOS phone with a USB-C OTG cable to unlock stereo audio, images, text broadcasts, recording and offline E-Learning through the Streamline apps.

    3

    Stay protected with EWF

    In sleep mode the N88 wakes every 30 seconds to check for emergency signals, switches automatically to the warning broadcast, and raises the volume with a flashing OLED alert.

    Public Safety

    Emergency Warning Function (EWF)

    Public Safety & Disaster Relief Radio Broadcasts Without Internet

    The N88 natively supports the DRM Emergency Warning Function. During natural disasters or civil emergencies, broadcasting stations can wake up the radio and transmit crucial audio and text instructions.

    Auto-Wake (Sleep Mode): Wakes up every 30 seconds to check for active emergency warning signals.

    Automatic Channel Switch: Automatically switches to the emergency warning broadcast channel.

    Visual & Audio Alert: Flashing OLED screen and automatic volume increase (~77% level or higher).

    DRM Priority & AM/FM Fallback: Prioritises DRM digital channels and falls back to AM/FM if required.

    FAQ

    Frequently asked questions

    Digital Radio Mondiale (DRM) is the ITU-recommended digital standard for MW, SW and VHF broadcasting. It delivers clearer audio plus text and data services over the same long-range bands as AM/FM. The N88 receives DRM alongside traditional AM and FM.
    In sleep mode the N88 wakes every 30 seconds to check for active emergency signals. When a warning is broadcast, it switches automatically to the emergency channel, flashes the OLED screen and raises the volume to about 77% or higher. It prioritises DRM channels and falls back to AM/FM if required.
    The N88 runs on 3x AA batteries (Alkaline, Lithium, NiMH, NiZn or Zinc-Carbon). Alkaline and Lithium give over 24 hours of listening, NiZn 15–18 hours and Zinc-Carbon 4–8 hours. It can also run from 5V DC via USB-C, which bypasses the AA batteries.
    On Android: Streamline MF/HF (DRM30 medium and shortwave) and Streamline Plus VHF (DRM Mode E). On iOS: StreamLine App (MF/HF) and DRM Video Plus App (VHF). Connect the radio via a USB-C OTG cable.
    A fully extendable 360° telescopic whip covers HF and VHF. For Medium Wave, a loop antenna is built inside the lanyard, and the hanging lanyard also acts as a ground radial to boost Shortwave/VHF reception.
