Yaesu FTM-400XDE vs Yaesu FTM-500DE
Home / Comparison / Yaesu FTM-400XDE vs Yaesu FTM-500DE
Yaesu FTM-400XDE or Yaesu FTM-500DE? I put both radios side by side: data from the manufacturers’ spec sheets and photos to the same scale. The Yaesu FTM-400XDE comes out ahead on weight and memory channels; the Yaesu FTM-500DE on Bluetooth and transmit current draw. Both radios support C4FM, so they’ll talk to each other digitally as well.
