• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Vertex has been making and selling P25 commercial HTs for several years now. It's not such a stretch for them to come out with a dualband P25 radio under the Yaesu (amateur line) brand. Remember that they're now owned by Motorola.

Very interesting... Too bad Yaesu does not update their website often enough

It would be nice if it was P25, but as we all know just because it's IMBE doesnt mean its P25. I'll keep my fingers crossed.

But, 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?


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.

It may be only for the Japanese market.
Yaesu (Vertex Standard) doesn't have any recent FCC Authorization grants for it.

Either of these two links will answer your questions. Since Yaesu is part of Vertex and Vertex
is now owned by Motorola you can draw your own conclusions after reading the info in those links.

Project 25 - Wikipedia, the free encyclopedia

Project 25 - The RadioReference Wiki

If 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
We do not yet know the politics of this pre-release info. We may have to wait to get the
skinny on that, but if it was DSTAR it would not be IMBE but rather AMBE.

I bet it's some DMR thing.
If it were DMR it would be TDMA and not FDMA.

Isn't conventional operation in IMBE the same as conventional operation in P25? GARY N4KVE
Yes if you are referring to Motorola Astro P25

It may be only for the Japanese market.
Yaesu (Vertex Standard) doesn't have any recent FCC Authorization grants for it.
This is also possible but again we won't know more until an official announcement.

MOTOTRBO is TDMA. IDAS (Icom) and NEXEDGE (Kenwood) DMR are FDMA.

Also, M/A Com's ProVoice uses the C4FM, IMBE and FDMA as well. That is why their radios are capable of using ProVoice or P25. The European TETRA is also based on C4FM an FDMA.
