Cover the wide-open spaces

With a whopping 40 watts of power and an external magnetic-mount antenna (sold separately), you'll enjoy remarkable range and reliability over open terrain. You'll be able to access 8 repeater channels and 15 high/low power channels with the easy-to-reach buttons, while 142 privacy codes make it highly unlikely that you'll trip over anyone else's transmissions. You can scan channels, too, so you won't miss anything important. You can use it to communicate with any other Midland GMRS radio, as well as most walkie-talkies.

Keep up with the weather

It's essential to keep up with changing conditions in the field, so the MXT400 gives you 10 NOAA weather channels. If a front's rolling in, you'll be able to plan accordingly and get to a safe place.

Clarity and control

This radio boats plenty of power, but it also offers some smart features. "Silent mode" operation ensures keeps distracting beeps and tones out of the mix entirely. You'll also appreciate features like auto-squelch, monitor mode, keypad lock, an external speaker jack, digital volume controls, and a backlit high-contrast LCD that's easy to see, day or night.

Installs wherever you need it

The MXT400 is easy to install in your home or vehicle. The detachable flip-frame mount secures on or under the dash, and you can slide the radio out when you need to. Midland includes a 12-volt adapter for mobile use. An antenna and mount (sold separately) are also recommended for this radio.

Product Research

Features

Overview: The Midland MXT400 is a GMRS (General Mobile Radio Service) two-way radio with a broadcast range of up to three times that of standard, hand-held, two-way radios (walkie talkies) providing a full 40 watts of power for a maximum operational range of up to 65 miles. Key features include: 15 high power GMRS channels, 8 repeater channels for increased range, 142 privacy codes, Auto channel-scan, and Silent Operation. The MXT400 is compatible with all Midland and most other brands of GMRS radios. Its compact and durable housing can be mounted under a dashboard or glove box with the included mounting hardware, and it also includes a hand-held PTT (push to talk) microphone. MXTA11 GMRS antenna and MXTA12 antenna mount sold separately.

Note: Operation of a GMRS radio requires an FCC license.

Range: With 40 watts of power, the MXT400 can provide exceptional communication range. The following is an estimated range guide:

  • Maximum distance is up to 65  miles line of sight with no obstructions.
  • 15 - 20 miles with partially obstructed line of sight (trees, small hills, etc).
  • 5 - 10 miles with major obstructions to line of sight (buildings, larger hills, mountains, etc).

Channels: The MXT400 provides 15 GMRS channels that can be selected manually or with the Auto-scan mode that continuously scans all 15 available channels for activity. It also includes a Monitor Mode that lets you check for activity on the currently selected channel. This mode also lets you adjust the volume of the radio if you're not receiving a signal from an assigned transmitter. The MXT400 has the ability to access up to 8 repeater channels which can significantly increase the radio's range and coverage area.

Squelch and Privacy: Squelch is the ability of a transmitter/receiver to suppress or mute the channel if the signal level weakens enough. This helps keep out unwanted channel noise and stray signals from other devices, especially when there's no signal being sent from a transmitting device. The MXT400 has adjustable Squelch sensitivity, with a level of 00 being the most sensitive allowing the squelch to open on very weak signals and a maximum setting of 09 which requires a very strong signal to open the squelch. The radio also features Privacy Codes via CTCSS (Continuous Tone Coded Squelch System) and DCS (Digitally Coded Squelch). These systems allow several users to share the same channel without disturbing each other. When CTCSS or DCS is enabled for a selected channel, the channel is muted to all incoming signals unless they carry the correct CTCSS or DCS tone. When a transmission with the correct tone is received, the mute is lifted and the voice audio can be heard. The MXT400 has 142 total Privacy Codes, 38 CTCSS and 104 DCS.

Menus: The following are the 11 menu options available on the MXT400:

  • TX: Transmit. This selection allows the transmitter to be disabled if using the radio as a receiver only.
  • Talk: Talk Around Function. This allows you to directly communicate with other radios in your group when the repeater is not active or out of range.
  • Comp: Voice Compander. This function is used to reduce background noise and enhance audio clarity, especially in long range communication.
  • Mute: Silent Operation. When this function is On, all operational "beeps" and "tones" are disabled.
  • Call: Call Alert. Used to select one of 5 available tones to alert of an incoming message.
  • TOT: Time Out Timer. This limits the amount of transmitting time the radio has per PTT activation.
  • APO: Auto Power-Off. Allows you to set a time interval to automatically power the radio off after no use.
  • SQL: Adjusts the Squelch Sensitivity.
