Upgrade! Yaesu FTM-400XDR Review

Yaesu FTM-400XDR

I recently purchased the Yaesu FTM-400XDR VHF/UHF C4FM transceiver while on sale for Christmas 2018.  I’ve been wanting this radio for a couple years, and finally the moon and stars aligned just right so I made the purchase.  So far this has been a great decision, I definitely recommend this radio!

Here’s what I like:

  • Super sexy 3.5″ full color screen with remote mount and cable included.
  • Touch screen operation!!
  • Dual band VHF/UHF, cross-band capable.
  • Dual receivers – scan and monitor two banks at the same time.
  • GPS position reporting – APRS and C4FM.
  • Built-in APRS modem – see distance and location of other reporting stations.
  • Altitude, clock and timer.
  • Program and back up using SD card and/or included USB cable.
  • Excellent quality audio, both transmit and receive.
  • C4FM digital, automatic mode select (AMS) or fixed analog, wide or narrow digital.

Annoying quirks:

  • The display is mounted separate from the radio body, no way to mount to the body.
  • The display may be mounted several feet away from the radio body.  The display is where the action is!  But the speaker is built into the body, a problem if you mount it under a seat or in the trunk of your car.
  • The microphone is plugged into the radio body, not in the display.
  • Depending on your installation, you may need to buy extension cables for your microphone and external speaker.
  • WIRES-X digital C4FM only works on Band “A”.
  • APRS only works on band “B”.
  • If you forget to turn off the APRS modem, band “B” will not receive regular analog transmissions.  You may see signals received on the display, but no audio comes through.
  • (April 2019) I recently started using a digital MMDVM hotspot (generic china “JumboSpot”).  Tuned band “A” to the hotspot frequency and it seemed to connect okay.  But I heard an annoying beep noise at the beginning of each received transmission.  I was able to remove the noise by setting the radio in fixed Digital Narrow mode.  Perhaps I was hearing a bit of digital noise while the Automatic Mode Select figured out what I was receiving then switched to digital mode.

  1. Just turn off the mite setting with APRS mute and you can hear audio while your radio listens for packets

    1. Hi Jimmy,

      The Yaesu FTM-400 is highly recommended and I’m sure you will enjoy it! I love the large color display, it’s easy on my tired eyes.

      I was running a “chinesium” generic hotspot powered by a Raspberry Pi Zero. Unfortunately the performance is not up to standard with lots of lag and weird noise spikes, so I unplugged it until I get around to upgrades.
