Why DMR is succeeding

A Happy Valentine's Day to everyone!

As many of you know, I am a big fan of DStar. Sure it has some limitations,
but for versatility, it is the best for ham radio in my opinion, because it
was designed for ham radio. Fusion can make that same claim, but I do not
see the versatility there.

DMR is a commercial standard adapted to amateur radio. It seems to be the
least flexible for amateur radio, but seems to be growing the fastest at
this point. The reason why is what I will try to answer.


DMR took over just as Microsoft did in the computer years. MS wasnted
about $ 50 and the other company (believe Digital Research) that I
forget the name of wanted about $ 150.

I company can not come out with a system for the population and keep
everything in house. Thatis what happened to D-Star, Betamax and some
of the eairly computer such as Texas Instruments. It also has to be the
less expensive, especially for hams. Copper wire was invented by 2 hams
arguing over a penny.



I'm no fan of DSTAR but how has it been kept 'in-house'? The overall
system isn't Icom's invention, in came out of work done by the JARL.
Icom did build the first kit based on the spec. and Kenwood offered the
odd one or two models.

The high price of DSTAR kit, certainly in the UK, is a large factor. A
DMR handheld can be bought (new) for about £100 ($150) a fraction of the
cheapest DSTAR radio. Unlike the US, surplus DMR kit isn't that common.

An interesting thing to notice: amateurs tend to like 'bells and
whistles' on their radios- memories, flashy displays, ...... which the
manufacturers are happy to 'feed' them. (Look at the new Kenwood DStar
handheld.) However, the cheap DMR radios are the Model T Fords - mass
produced for the wider market and functional. How long before amateurs
notice their don't need a colour display with a built in coffee maker?

It has been kept "in the amateur radio house".
DMR is mainly used outside of that, so there is a source of surplus
equipment, a large market with competition, and some manufacturers that
make amateur equipment as a special version of devices they also sell
on their regular market. This makes it easier for them to sell devices
at a lower pricepoint than amateur radio equipment manufacturers can.

That is a fair point but it is true of much of our other kit yet we
don't see the same situation we do with DSTAR and DMR.

The nearest parallel would be the availability of cheap 'Chinese'
analogue radios which have undercut the offerings from the traditional
amateur manufacturers which tend to offer more bells and whistles etc.
The latter are still on sale in the UK but, I suspect, are suffering.

I don't have an axe to grind here, I'm not in the business nor pro or
anti either DSTAR or DMR (I do have a DMR radio). I'm just trying to
understand where things are going.

Me neither. I am not QRV on any of the digital voice modes, as I consider
the voice quality of the typical codecs too low.

However, when looking at the state of the network here it is clear that
the initial deployment was on D-Star but it has largely been overtaken
by DMR. Especially now that free software is available to run the network
and there is no dependence on MARC and its policies anymore.

Fusion is a failure. Yaesu has failed to provide usable firmware for
the first repeater, and "to fix that" they have released new hardware,
essentially leaving those that bought the original kit in the cold.

As a result, people are now ripping out the controller hardware and
converting them to plain voice repeaters using a working controller.

I resisted for some time but decided to try DMR. I did try DStar using
other people's radios and have never been impressed.

I would say DMR will 'win' here, mainly due to price I suspect.

We have some Fusion boxes but it seems like madness for Yaesu to go for
another system.

If you mean analogue, I've not heard of that here.

Sure, but what really nailed is is their failure to implement it.
The repeater firmware and associated network application sucks, updates
have been promised for a long time and every time they were postponed,
and finally a new repeater appeared to solve the problem.
Most people here feel that they were lured into buying a cheap repeater,
understanding that Yaesu did this to promote sales of mobiles and portables,
and not knowing that they only did this to dump unusable hardware before
releasing a new type.

Usually analogue, but I have seen a tweet about multimode use as
well (MMDVM).

I wasn't aware of that, I confess to not following the progress of
Fusion, or lack of it, in detail.
