The label placed on the glass case in front of the ht has "C4FM" and "FDMA" in english
on it and if it is FDMA then it must be IMBE.
Either of these two links will answer your questions. Since Yaesu is part of Vertex and VertexBut, IMBE is a vocoder type. It can be implemented on any air interface as long as there is enough data to move it. C4FM on the label is just the modulation (air interface) type. That's my understanding or am I missing something?
We do not yet know the politics of this pre-release info. We may have to wait to get theIf it was P25 it would probably say P25 since that would be a huge selling point. If this were a Icom it would say DSTAR, not digital or C4FM, cuz that would not be the way to advertise it. prcguy
If it were DMR it would be TDMA and not FDMA.I bet it's some DMR thing.
Yes if you are referring to Motorola Astro P25Isn't conventional operation in IMBE the same as conventional operation in P25? GARY N4KVE
This is also possible but again we won't know more until an official announcement.It may be only for the Japanese market.
Yaesu (Vertex Standard) doesn't have any recent FCC Authorization grants for it.
