Adding D-STAR to a Yaesu DR-1X Fusion Repeater

[Tom Azlin W7SUA]

Hi.

Food for thought....

Turns out that the Yaesu FM/Fusion repeaters make excellent three mode
repeaters that can operate in FM, Fusion, and D-STAR mode on a per
transmission basis. The Fusion repeaters are so clean that they
discovered the bit error rate was much lower than when modifying older
Kenwood FM repeaters for D-STAR use.

Read about it at http://nwdigitalradio.com/introducing-the-udrc

This was reported by John Hays K7VE on the NW Digital Radio email
announcements group. Also sent out on the Yahoo pcrepeatercontroller
group that is where home brew non-Icom D-STAR radios and repeaters are
discussed.

Turns out that both the Fusion and D-STAR protocols are openly available
( if a bit obscure as some in Japanese) so appears was easy to make this
work. Also saw in another article that a ham in Florida is working on a
transceiver that will do FM, Fusion, and D-STAR. Is in the brass-board
stage now. This project also uses the unrestricted Codec2 vocoder
software as another alternative.

As an aside, the folks that make a GMSK Digital Voice modem board found
at http://dvrptr.net (that is used to roll your own D-STAR repeater) now
have created a DMR <-> D-STAR gateway. Software for that is available.

So getting to be not much proprietary in any of these digital voice
repeaters other than they all use the AMBE vocoders from Digital Voice
Systems, Inc that can be easily purchased in single unit quantities for
ham radio experimenting. If the mainstream manufactures will not
integrate these systems is up to the ham radio community.

Might be the NVFMA dual FM/P25 repeater can be tied to the NVFMA D-STAR
repeater is a similar way.

Thanks for reading this. Out here in central AZ very few D-STAR
repeaters but I know of seven Yaesu Fusion repeaters that have been
ordered. I am working on getting a D-STAR hot spot working and would
connect it to the NVFMA stack as soon as it is possible for me to link in.

Hi, Tom. Good to see you on this reflector. That's very interesting
about the ability to use the Yaesu FMT repeaters with a D-Star
interconnection.

I look forward to seeing and hearing you on the NVFMA gateway or through
Ref 25B.

Hi Steve,

Good to hear from you. I frequently forget to turn on my D-STAR HT and
connect to 025B. I will do this more often. I am running a little
Raspberry Pi with hot spot and ircDDB software. Hopefully soon I will
also be able to connect to NV4FM directly. Will try to remember tonight
as I usually join the VWS digital net which is around 7073 KHz in Olivia
16/500.

Pat and I were hoping to make it to NoVA this month but have changed our
plans. So in addition to connecting via D-STAR, I am up for HF skeds.
Mostly I operate various digital modes with my big 80m off set fed
inverted V.

Have also been playing with new mode/program FSQCALL on dial 10,144 KHz.
Out here in the West is a sort of party line.

Is fun living out here. just a few days ago a Bobcat sauntered across
our flagstone patio, stopped and turned to look at us for a few minutes,
then turned back and headed into our back yard desert landscape. Pat saw
him/her once before carrying a big rabbit across our patio.

Hi Steve.

I am still interested in the NVFMA and the D-STAR repeater there.

Here, so far not much interest in that add on board.

We have the K7NAZ repeater on the air with 2m and 70cm. Is about 45
miles from our house but line of sight up at 9300 ft. In June we hope to
get the gateway hooked up. Bit of a challenge bringing internet to the
mountain top without paying many hundreds a month if not many times that.

I hope to switch one of the bands to REF025 or as soon as the NV4FM
repeater can be linked to by me then perhaps directly.

Otherwise I am around on HF and set up a hot spot from time to time.

Hi Bill,

Not sure how that applies to discussion of Yaesu Fusion or JARL D-STAR.
