Yaesu FTM-400XDR C4FM Transceiver Review

I like the large touch screen, in a world where everything is getting smaller this was a breath of fresh air. It is responsive, but a little difficult to see in direct sunlight. I like radios with remote heads, but the microphone cable plugs into the body.

I found it equally easy to program by hand or with the software. The cross band repeat is the best feature, it works well and I use it regularly. The radio does get hot on high power during long QSOs. I absolutely favor it over the FTM 300DR just for the display alone.

The microphone is adequate, but I find using the DTMF buttons difficult with my large fingers. The C4FM is clear and I do not do APRS so I can not review that. Dual band monitoring works nicely and is  great for monitoring 2 bands,  or talking on one and monitoring another.
