Rated 5 out of 5 by from Jeep Wrangler Rubicon MXT400 & MXTA26 WHIP ANTENNA I read the reviews before purchasing this radio and antenna. The radio and antenna certainly live up to the hype. It is small, light weight, and well built. The radio was engineered with inline fuses making it easy to work on should you blow one and also easy to add to a pillar switch pod. The repeater channels offer great range while wheeling or hunting. The MXT400 works well with hand held radios who are spotting while wheeling or communicating with blockers during pheasant hunting season. Easy to install, easy to use, and offers good communication clarity Jeep to Jeep or Jeep to handheld.

Rated 5 out of 5 by from I just installed this radio in my truck. Very impressive radio. The range talking to my wife who was using a Garmin Rino inside the house and me on the MXT400 on high power was about 7 miles in an urban setting. One of the reviews stated privacy codes did not work. I found that they do indeed work. Follow the manual on setting the codes. I suspect people are using the DCS codes vs the CTCSS codes where you look at the manual and cross reference the privacy code to the frequency you must select under CTCSS. Works perfect.

Rated 5 out of 5 by from One of the few legal (FCC part 95) radios. I received this radio 2 weeks ago. It is temporally using a Tram 1170 UHF mag mount antenna. The SWR is at 1.1 to 1. (Previously tuned to GMRS frequencies. With the antenna centered on my roof. Ford f250. I was using it on Long Beach Wa. On low power I was consistently hitting a repeater in Astoria Or. I had tried it on medium pwr, 22 watts, but that was not necessary as long as I was on the the beach. This is a distance of approximately 20+ miles. I do not know the height of the repeater in Astoria. Hope this helps. Keith T.

Rated 5 out of 5 by from MXT400 - Awesome Radio I bought this because several other members of our Jeep club have GMRS radios. I wanted a radio that had high watts, because there are times when we are overlanding that I want that extra power for further range. I have it installed in the Jeep along the right side of the center console and liked the quality and reliability of it that I purchased a Midland CB to communicate with the other members that don't have GMRS.

Rated 5 out of 5 by from Excellent Midland thank you for finally creating a decent user friendly GMRS TYPE ACCEPTED radio. Seems to be sturdily built for a bit of rough handling just don’t get it wet. One improvement would be a software update to allow some storage of multiple repeaters with same frequency different power and tones. This would make my trips back to New York easier to switch back and forth same repeater freq different tones. Not going to reduce stars though. Good rig.

Rated 5 out of 5 by from This radio blew my mind the first time I used it. The most range I’ve ever gotten from a GMRS radio. I was able to talk to a friend with another MXT400 who was over 10 miles away in a decently wooded area. Don’t forget your FCC license!

Rated 5 out of 5 by from Good Value for a Part 95E certified GMRS radio We have had a pair of MXT400's for a week or so. They appear to have very sensitive receive capability. I have been able to pick up an individuals FRS (1/2 watt) Radio Shack wireless intercom from 28 miles and they only have a short antenna inside the house. The only concern is that you can only set the PL or DPL tones for both receive and transmit on the same tones. Some repeaters have different tones for input and output. The work around is to transmit the tone to open the repeater and use the open receive (no squelch) for receive.

Rated 5 out of 5 by from MXT400 great radio Got this radio in December. I have been pleased since the install. I’m getting about 5 miles with my Jeep and a handheld walkie radio. The volume is fantastic. I purchased the external speaker and haven’t needed to instill it. Thank you MidlandUSA

Do I need to check the SWR when I install the radio/antenna or is it preset?

No need for a SWR meter with GMRS MicroMobiles, everything is already set.

Is the mxt400 compatible with a person to person intercom system ? 

Asked by: Thekid0085
It can likely be adapted by making a cable that plugs into both the external speaker jack and mic jack of the MXT400. For more information please contact [email protected]

Hello. I get the following message on the screen when I release the mic switch. DC-HI What does this mean?

Asked by: Borderpolman
The message "DC-HI" is the MXT400 detecting the input voltage above its normal operating range. The MXT400 high voltage detection is normally about 16V. It could be related to the type of vehicle it's installed in. If it only occurs briefly when PTT is released, that could indicate a smaller battery capacity.

When is the MTX400 replacement launching? I saw on another question here that on spring 2020 you guys will be launching the new radio. Do you have an exact release date or month? I just don’t want to buy the MTX400 if the new one is launching soon.

Asked by: DjManny128
Due to events out of our control we are now looking at a late 2020 release date.
