Building A System Fusion Simplex Node.
(Part1)
Forward:- From Yaesu UK.
System Fusion is Yaesu’s implementation of Digital
Amateur Radio, utilizing C4FM 4-level FSK Technology to transmit digital voice
and data over the Amateur radio bands. In the early 2000’s GMSK emerged in the
Amateur radio market as the dominant digital mode, however in 2013 Yaesu
introduced “System Fusion” which quickly became the dominating digital format
in Amateur radio because of quality, reliability and enhanced performance in a
wide range of environments.
The design of System Fusion was genius, allowing it to be
used as a digital or analogue system meaning hams did not have to go out and
replace their beloved favourite radio and buy more equipment to use the local
repeater. Well not strait away at leased 😊
This was something I hated about Dstar – If your local
repeater group “upgraded” the system to Dstar you had to go out and buy new
Icom only gear and let me tell you this was flipping expensive when Dstar hit
the market!
Along with the expense of Dstar, I personally found it
quite hard to setup & use. It was very overwhelming to me having to
register my call on a website just to use my radio.
“Maybe this has changed?”
Then I saw System Fusion & the Wire-x System.
To me the Wires-X system looks like EchoLink on steroids
with all the rooms & ability to drive the link or repeater anywhere you
want.
If you are running on Analogue then the use of DTMF Tones
are required to access the rooms you wish to access much like EchoLink, however if you are on Digital then you can get
the list of rooms sent to your radio!
Talking of Radios – Here are a couple, a HT & a Mobile.
I had been trying to convince my local ham radio club to
setup something digital for a while to no avail because at my location, Near
Malin Head – Co. Donegal, there are no digital systems to play with at all.
My plan is to setup a simplex system on UHF. I’m using
UHF as we run a 2m repeater here EI2IPG on EchoLink.
I think for the time being the system is going to be on
analogue as I don’t have any digital radios for this project, but I do have a
few handhelds I can use to monitor and talk through the system with.
The node radio is going to be a Motorola GM340 as I have
one of these setup on UHF Simplex.
The other item I need is a Wire-X Interface, the HRI-200
A company called Moonraker in the UK (www.moonraker.eu) had the interface in stock
so I ordered one.
This Interface will allow me to take full advantage of
the Wires-X system and give me the following features.
APRS
Voice Mail
News & WX
Warnings
Text messaging

Like I said before a fantastic system.
They sell a neat little device that plugs into the back
of the Motorola radios 16 pin socket to give you a 6-pin socket like on the
back of the Yaesu radio. (Motorola
Connector to mini-Din adaptors)
I believe these to have the same “industry Standard”
wiring so I should be able to plug the interface into this without any problems
– But I will be checking the wiring diagrams before use!
The Motorola
Connector to mini-Din adaptors are in kit form and are €7.50 + delivery to
Ireland.
At this moment in time I’m just waiting for items to
arrive to start building the node / link.
Check back soon when we start to build up all the parts
into a working system.
