Dmr

I am pretty certain that this will be ETSI 102 tier 2 compatible in the ham bands.

The FT1D FDMA version will not be TDMA capable, so it will be DMR in a 12.5 kHz channel in digital mode.

Looks like the messaging/GPS functions are enabled as well as image/data transfer modes as seen in commercial DMR tier 2 radios.

You can be quite sure the frequency mask will be locked down for NO OUT OF BAND TX, and there is probably some neutering of the DMR access so it cannot be used in the US on Part 90 systems.

Embedded GPS is a plus and an internal TNC as well if it is truly APRS capable.

Let's see the price point and whether it is disruptive enough to spur investments by stingy hams who think all radios should be under $100 - LOL

I am pretty sure this will not be a P25 CAI radio, just DMR/Analog with no TDMA.

No proof, just intuition here.

Craig

 

[mikewazowski]

I agree. Single frequency DMR with no timeslotting.

Unfortunately most people have assumed it will be P25.

I don't believe Yaesu would bring out two different standards.

I'm assuming (big mistake), that the timeslotted DMR radio will be backwards compatible with the non-timeslotted radio.

Hopefully they have the infrastructure ready to support both radios when they release it.

FT1D Vocoder

I think most, if not all, DMR implementations are using AMBE+ so I imagine the same vocoder will be used.

 

[kv5e]

$$$ ft-1d $$$

Currency coversion from Yen to US Dollar is at $~780.00 without marketing tweaks for US market.

I don't see this coming in at less than ~$600 with a bare bones charger and antenna.

Maybe some (cough cough, oh Ray Novak, cough) new promotions at Dayton might show up.

4FSK transceiver ASICS are pretty available now.....I know there's some Tier 1 DMR radios from PRC starting to be sold in ITU Region 1&3. Who knows what price compression is possible, although the Ham Market only radios without FCC approval for Part 90 might not see the numbers like Wouxun and other PRC manufacturers have made in market penetration.

Hytera has a nice Part 90 single band full featured DMR 2/3 with GPS and color/display at ~$700,

If this radio truly meets the DMR standard, then it will be TDMA (2-slot). And it will be compatible with MOTOTRBO.

John Rayfield, Jr. CETma

Time will tell if my speculation is true. NO reason a single slot radio cannot talk to others, but it is technically not a full implementation of Tier 2/3 then.

If it is a one-off 4FSK air interface like the then it will have trouble.

I am basing my guess upon Yaesu's reference to DMARC in their "bollocks" white paper.

Craig

 

[JRayfield]

Are you talking about simplex mode, when you refer to "single slot"?

I agree that since Yaesu referenced DMARC, that it's likely that they will come out with a DMR-compatible radio.

[kv5e]

John,

This is all speculation so they might be offering a single slot repeater system or who knows what.

They could be still working on TDMA on this device and flash upgrading later.....who knows.

I guess we will find out at Dayton.

If this is a 4 FSK DVOA type offering like the Unication U3, then it is a mistake on their part.

I have a question for you.

Have you implemented any designs in the mountain areas where propagation delays for TDMA start creating challenges?

I would be interested in your observations on this if you have.

Thanks in advance,

Craig

John, Criag..
With this popping up, why was the original broucher pulled???

My thought, the divorce from Mother M. (my opinion)

Emissions?

Evans,

I wondered if that was the reason they pulled the VXD-720 myself. Also, is it possible that Yaesu is waiting on the ARRL petition on 7K6FXE and 7K6FXD emissions to be added to the list of permitted emissions for the ARS.

I don't think the FCC cares if hams use "uncovered" DMR, but the permitted list does not include TDMA so maybe it is a legal point with them.

I have searched the OET files and found nothing there either.

The more DV the better in my book. More experimentation and learning is what I like about this hobby!

Craig

 

[JRayfield]

The VXD series of DMR products was/is not a 'Yaesu' product, it is a 'Vertex Standard' product. Yaesu has nothing to do with 'Vertex Standard', now. Vertex Standard is totally, 100%, Motorola-owned, now. So it makes sense that the VXD series of products will not be on the Yaesu website.

John you obviously did not know that yaesu displayed the vxd series on the amateur pages prior to getting kicked to the curb

[JRayfield]

That's make sense, since "Yaesu" still owned 20% of Vertex Standard. Once that arrangement ended, I can see why they wouldn't have it here.

Not sure what you mean by "kicked to the curb". Sounds like maybe you've got some kind of 'gripe' against Motorola?

Yaesu FT1D (C4FM Digital)

I was just reviewing the Yaesu brochure on-line again. Specifically, where it states:

".....At this point in time, Vertex Standard believes the C4FM (4-level FSK). FDMA or TDMA are the most suitable selections for Amateur radio applications. In early 2012, we will release a C4FM (4-level FSK) FDMA Handy-Talky and a Mobile transceiver into the Amateur market....."

I am actually more interested in a mobile than an HT, by any chance does anybody happen to know if it will be a Handy-Talky only at first? It sort of seems like that is what Yaesu has done in the past.

 

[N9NRA]

Intresting read here folks . I`ll be waiting patiently for Dayton to see just what comes off with this, my hope is this, personally i`d like to see some form of mototurbo, just so i could play with it a bit more than i got to last year . However, as has already been mentioned, i bet Yeasu is waiting on the ARRL filing with the FCC yet, just to see where that ends up going, reading what was in the original post was kinda confusing, but i have the feeling we`ll be seeing more info at Dayton. Keep your fingers crossed folks, and keep watchin`, it could get intresting. N9NRA

From interceptradio

 

[kb5udf]

tested it

Just back from yaesu booth tested 2 hts. Audio quality was good. brochure says 12.5khz c4fm fdma. Yaesu staff suggested there would be a later version of this radio that would be dmr compatible but not the initial version.

 

[kb5udf]

Upon further research

I've taken the time to educate myself a bit on the various digital two-way standards floating about.
Upon reflection with this data and the provided yaesu literature from Hamvention,
It sounds like the digital HT's I used are more angled to the NXDN flavor of digital rather than DMR;
the spec given for the HT's of C4FM and 12.5khz FDMA is consistent with NXDN, but is insufficient to show compatibility.

I'd take what I wrote previously about the yaesu's rep saying that there was DMR in its future, as he appeared to be not very enlightened about his products. (I had to figure out myself how to place
both units into digital mode, which turned out to be as simple as hitting a button with an italicized D).

Another reason to angle to the NXDN flavor of digital is potentially cost, while I know that DMR radios are coming down to more reasonble levels, it appears you can get by, from my research, with
a cheaper receiver (e.g. frequency stability of 2.5ppm vs .5 ppm needed for the TDMA of DMR). The VOCODER the FT1D uses is not specified in the product factsheet I received.

As a follow on to my above post I would add that the audio between HT's was very good to
my ears, despite being in a very noisy environment (a crowded arena). This suggests use
of an advanced vocoder.

 

[kv5e]

Thanks for the additional post.

FDMA is just a term to describe channelization. Users are divided by orthogonal frequencies or channels.
Analog repeaters are FDMA is all honesty.

TDMA or time division multiple access uses channel shared by users in the time domain or "slots". This technique requires a synchronization signal of some type or a disciplined time base. Precision timing data to keep users separated is most easliy done from the BTS with sync bursts transmitted to the user radios.

C4FM is term used originally by /\/\ for 4 FSK transmissions with a constant envelope. This modulation type can utilize Class C amplification which reduces the implementation costs. IMHO C4FM just means that the four level modulation has no amplitude component conveying information.

Four level modulation can also have amplitude modulation as in the case of phase II Project 25 where the amplification must have means of accurately controlling the amplitude envelope of the transmitted waveforms.

Yaesu lists the symbol rate as 9600 bps (control plane included) so that is going to take up 12.5 kHz channels unlike NXDN which fits in 6.25 kHz channels.

The TDMA is needed for DMR/P25 to meet the Part 90 narrowbanding requirements which state that the bandwidth and symbol rates needed for digital emission compliance are 4800 bps in a 6.25 kHz channel at a later date.

DMR and Project 25 phase II gets there by having two communications paths in a 9600 bps channel at 12.5 kHz occupied bandwidth.

TDMA can have some significant challenges once propagation delay becomes long enough to create synchronization problems. This has been an issue from the IS-136 days until today.
