MicroMobile Two Way Radio is rated 4.8 out of 5 by 58.
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 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 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 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 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 2 out of 5 by from Feature packed. But missing vital items So far, not sure if it's really any better then the MXT115, which I purchased right after t he 400. It's a bigger radio so if anything, the extra power is fine even if it's missing what I consider one of 3 important items it SHOULD have come with. 1. No 12v accessory plug/cable. Sure, it has a fused cable but seems someone forgot to pack the accessory plug end of the cable. This comes with the MXT115 2. No antenna. Ok, again, the MXT115 comes with one, this does not. I used both radios on my purchased antenna. They seem the have the SAME distance. 3. 400 has no WX channels. Again, the MXT115 does. Why this feature was ignored kinda makes the 115 a better option for outdoor use. Just saying, the radio itself is fine. If all you care about is the power, and ok with picking out and buying your own radio, go for it. But IMO, the MXT115 is a MUCH better deal, has about the same range from my tests and comes with a much better out of the box experience and features.

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 4 out of 5 by from Functionality works great. Features are nice. The only issue I have with it is that it is only 35W, not the advertised 40W, according to my power meter. I would still buy the radio, but please note that it didn’t put out the rated power.

Will future MXT400 releases (or similar successor products) have NOAA channels? I would really like this weather capability in my Tractor without a separate device.

Can the receive ctcss be turned off when accessing repeaters, even when the transmit ctcss is necessary to open the repeater? Got a gmrs repeater locally using different receive vs transmit tones.

Asked by: DB66
Negative, at this time we cannot do split PL tones but it is a focus for our next MicroMobile radio due out in Spring of 2020!

I have limited dashboard space but want a 40W transceiver. I have a 75-822 CB and want the the integrated microphone/display from the MXT275 to go with it. Will that mic work with the MXT400?

Asked by: Derphound01
Hello there, The 75-822 is a CB radio and the MXT275 is a GMRS radio, so you will not be able to use parts interchangeably as they function on two completely different bands. The MXT400 is also a GMRS radio but you are unable to use the MXT275 mic with it again because that is not the intended function of those radios. The "brains" of the MXT275 radio are actually in the mic, so it will only function with it's base. We will have a new higher powered GMRS MicroMobile this Winter that will use the same set up of the MXT275 mic. Opt in to receiving emails from us to keep an eye out for updates!

Does any of the micro GMRS radios, also be able to talk on FRS channels? or is it just GMRS channels?

Asked by: Newbie
If you mean the FRS channels 8-14 that would be a negative - the FCC does not allow for radios to transmit over .5W of power on those channels nor are you allowed to have radios with detached antennas on those channels. All FRS radios can access channels 1-7 and 15 - 22 however, so you are able to communicate with FRS radios as long as you are using those!
