Yaesu FTM-400XDR

The FTM-400XDR is a very common 2m/70cm C4FM/FM touchscreen mobile. No CAT control on this model. Audio and an active-low PTT come from the 10-pin mini-DIN DATA port to a USB radio interface. Program channels from the front panel or Yaesu programming software; ORLP cannot change frequency at runtime. For an analog ORLP node, operate the radio in FM (analog) mode — do not link C4FM (System Fusion) digital audio into an analog node.
