RX: 108-990MHz

The new FTM-400XD includes an improved GPS receiver that employs the latest in GPS technology providing faster and more accurate satellite searching fuctionality. These advancements will reduce GPS Time-to-First- Fix (TTF) thereby speeding up navigation and telemetry functions.


Yaesu FTM-400XDR - 2m/430MHz: 50W FM, C4FM FDMA w/ GPS for APRS(1200/9600bps), Micro SD
RX: 108-990MHz

The FTM-400XD uses C4FM FDMA (C4FM – 4-level FSK Modulation, FDMA – Frequency Division Multiple Access), which has been developed for the professional LMR communications. It uses this enhanced technology for a lower BER (bit error rate), resulting in stable communications without interruptions during mobile operations, even in a rapidly moving vehicle.

  1. Great UI, but still missing some features 5 Star Review

    Posted by on 12th Nov 2019

    I needed a dual band radio for emergency use in the back country. APRS was a top priority as I am in the mounatins and many mountain top repeaters beacon out on APRS. It is the best way to figure out what repeater you are line of sight with.

    I did not want a Fusion radio unless it also supported D-Star and DMR. It is inappropriate for a Yaesu to make a proprietary mode without also supporting the preexisting modes. Almost bought the TM-710, but in the end, that radio was way too much money for such an outdated feature set. Too bad they don't have a mobile equivalent to the TH-74. I just couldn't wait any longer for Kenwood to catch up.

    Back to the FTM-400. The UI is awesome. I was worried about a touchscreen in a vehicle, but it works well enough for how I use it.

    Analog sound quality seems good. Fusion sound quality is ok, but stations that are far away get rather pinched and nasally when bits start getting lost. Better than computer noise, but not sure that it is much nicer to hear than analog FM.

    APRS works great. You can put it in the B-band muted with voice alert on. It will happily run in that band independent of what you are doing in the A-band. No need to keep the B-band selected for transmit. It will only send APRS in B and you can transmit voice in A.

    Here are the disappointments:
    -Radio has GPS and my repeater source data has repeater lat and long. I should be able to input repeater locations and the radio should be able to filter the memories by distance so you can see what repeater is closest. There is no reason that this feature isn't implemented. It would have cost about 2 days of programmer time to implement. Not acceptable.
    -500 memories? there is an SD card slot. I should be able to program every repeater in the directory with the unlimited memory. Why the arbitrary limit on memory count? Why can't I download the world wide repeater directory from Yaesu every month and plug it into my radio. You could still have a internal memory list of say 500 for the local repeaters, but there is no reaon to make me have to program my radio to make it work when I am on the road.
    -APRS list sort feature is about useless as each new station comes in at the top and what you sorted is now scrolling away down the page. Sort should also sort each new incoming message.
    -You have to select VFO mode before clicking on an APRS message frequency, offset, and tone. C'mon Yaesu, you decided you need VFO mode, good for you, now switch the radio into VFO mode and program the frequency. That ould have been 1 additional line of code for you.
    -There is no way to see more than 1 relative station location. Should be a depiction of each station in 2D with range rings at 10,25,50, and 100 miles. No need for a background map, just need to see relative locations of each call sign. You have a touch screen, I should then be able to select a call based on location and message them.
    -Too easy to transmit on digital when you are on an analog channel. Would prefer if you could specify in the memories if it is a digital enabled channel or not.

    The rest is great, buy the radio, unless someone comes out with a D-Star+DMR+APRS+FM dual band mobile radio with a location sorted memory listing. The FTM-400 will be obsolete on that day.

  2. The Cadillac of Yaesu Fusion Mobile Radios 5 Star Review

    Posted by on 1st Oct 2018

    The Yaesu FTM-400XDR is the top of the line when it comes to Yaesu Fusion mobile radios! Crisp and bold transmit audio with plenty of high-end will guarantee that you will be heard and understood. Receive audio is clean and loud as well. This is a true dual band, dual receive radio which will allow you to monitor 2 analog signals at the same time or 1 analog and 1 digital voice signal at the same time. (You cannot monitor 2 digital voice signals at the same time; only the top band allows you to monitor digital voice).

    The micro SD card slot makes it a cinch to update the programming in your radio without having to drag a laptop into your car. (Note that firmware updates will most likely require that the radio be tethered to a PC; the special programming cable IS included and can be used for updating memory programming too). This radio came with the very latest firmware update already installed, so I didn't need to mess with that. My only wish is that this radio would be able to store the operating mode (ie: FM or DW or DN) into a memory channel as the newer FT-70 HT does.

    Thankfully, Yaesu has finally introduced several less expensive options for getting into Fusion, and from what I've heard, they are also great radios. However, the FTM-400XDR is the best of the best, and, thanks to a recent special at Main Trading Company, I got it for the best deal I've ever seen - and I've been watching for a few years.

  3. Yaesu FTM-400XDR 5 Star Review

    Posted by on 7th Jun 2018

    Initially ordered radio from MTC and they were out of stock and decided to order elsewhere. Then that night I received a call around 6pm telling me they had just gotten some in and wanted to know if I still was interested. I ordered one the very next day and am glad I did. I love the radio and it's exactly what I was looking for in a mobile rig. Replaced my FTM-100 which is now a Wires-X node radio. Really glad I ordered from MTC. Sure it might have cost a little more because I had to pay tax being that I live in Texas but the customer service is 2nd to none and I will continue ordering from MTC in the future.
