Default Yaesu FT1DR/E

So, I opened a QST and found this "12.5 kHz C4FM FDMA" FT1DR/E on the back cover. I've never before felt like a description could tell me everything and nothing both at the same time. Any of you know what this is compatible (or maybe better, not compatible) with? For example, would it go through my 2 meter Quantar and be able to communicate with my EFJ 5100 in P25? Or is it something completely different (as if the amateur market needed another different digital protocol)? Anyone have an inside track on whether this thing can talk to anything other than itself (like the Alincos do/did/whatever)?

From what I hear, and this is secondhand mind you, Yeasu said that the digital mode is similar to P25, but entirely incompatible and unique, which to me seems a waste, but hey.

Go to the Digital Voice for Amatuer Use forum a bit futher down from this one. It's been hashed to death since the announcement that Yaesu was going to have digital voice radios. You'll not be the only one who has scratched their head over this topic

From what I heard from Yeasue when I was at Dayton. That the C4FM part was not P25 persay but was going to be a yaesu version of digital and also I was told by a Yaesu rep that the radio would also work with Motorola Trbo.

The whole world waited until Dayton for Yaesu to intro this radio. Sadly it will only talk in digital mode to another FT1DR, so it's quite useless. What a waste!!! GARY N4KVE

True. I think it's quite possible that yaesu thought our impulse would be to order that piece of crap with the mistaken impression that this would be a cheaper way to buy a P25 radio without having to deal with moto's protocol issues hoping the amateur radio consumers would bite, but not so much.
Yaesu marketing guru's dropped the ball this time.

Ya know, I wonder about what these amateur radio manufacturers in Japan think of their American market. I've always thought that they are less about performance and practical application, and more about toys and gadgets. I wonder if there is just so much of a cultural divide that they're pushing stuff to a market they just don't understand. At all.

Smile Why?

They make theses things so small and (silver) toy looking. The VX series overloaded with functions and features and tiny buttons, let alone menu structure that requires you to either memorize a 1/2" thick manual or buy an after market "cheat sheet manual" to carry with ya to remember what things do what. Again, Yaesu made a toy looking radio and this time they will be able to write off the American market as it isn't compatible with anything used here in the digital realm. I for one really wanted this to be DMR - TRBO compatible.. Oh, well. Build it and they will buy it. Wonder how many suckers will have to be first adapters and just gotta have one? But, I am just beating a dead horse, again. I am quite happy with DMR - TRBO it just works great for me. This weekend a phone call to HRO, a sales rep on the phone KNEW NOTHING about this radio at all!!! Yaesu struck out with this release. Ain't it grand.

C4FM FDMA is a new version of digital that is now being explored by many services. With this mode, you can go into the HF bands and listen to military and other digital SSB modes with this. It is new but much better than P25 and DSTAR. The autocorrect is ten times better than these other digital modes. You can setup the Yaesu FT1DR with software to convert between C4FM to P25. In time....this will be very useful as more are converting to this! Your one step ahead in technology!

More details, please.

AFAIK, the Yaesu System Fusion (YSF) version of C4FM and P25 are NOT compatible with one another and I am not aware of any software that would turn a YSF radio into a P25 radio. If it's true, I'd like to know more!

This must be the same software that will decrypt AES-256...let me tell you about a bridge in Brooklyn, NY I can make you a GREAT deal on.

I can confirm that Yaesu's use of C4FM FDMA is NOT compatible with P25, at least the way the FT-1DR comes from the factory. But it does sound better than D-Star. Looks like a "VHS vs Beta home video player" battle is brewing in the amateur radio world...may the best man win!

Guys - C4FM is just a modulation technique to get data from point A to point B. It's not the protocol that runs across it. NXDN and D-STAR are also C4FM, but the protocols are different.

Using C4FM doesn't mean that the equipment is directly able to communicate with one another.

I greatly doubt that anyone will develop a firmware flash to load in the P25 phase I protocol into these radios. If anyone does, it will probably be Yaesu to stretch the product into the P25 market -- and it probably would not be the version available to amateurs, locking out any desirable characteristics hams like (frequency agility...).

Since my original post in 2012, it seems these were intended to be stand-alone products within their own systems and are offered as-is. Can someone "hack" them? I don't see why not, but I sure don't have the time or expertise or equipment or desire to do that.
