In my humble opinion, its a control box, and probably a prototype at
that. The reason I say proto is that the function switch is not human
engineered properly. The knobs are way too close together and any
ergo-engineer would handily reject the design. The fact that DME is
even mentioned is arguably for control purposes, only. And, what does
"DME off" mean? Is it the R/T unit or the audio ident? The low/stby and
hi refers to what? Selectable low/high us usually relegated to the
75Mhz marker beacon receiver. Now, it may well be that the concentric
freq knobs are the wrong ones. If smaller ones were used, maybe the
selector switch would be OK? Again, it screams out to be a proto box as
it does not comply with any standard ARINC label or layout.
