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.
- 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.
