Greetings all, the question keeps coming up about YSF and Wires-X. What is the difference? Can I connect my hotspot to a Wires-X room? The answer really is NO, since YSF and Wires-X are not the same but use the same modulation technique.
You can however, by connecting your hotspot to a YSF Reflector room that is then bridged to Wires-X through a node radio or other system used, then be heard on a Wires-X room that is so equipped, such as we do with SkyHubLink. Gets complicated to understand
sometimes, but here is a more detailed explanation as is on our SkyHubLink website:
So, what is the difference between YSF and Yaesu "System Fusion"? This is a subject of confusion for some, so here is a simplified explanation:
Lets go over some terms that will make it easier to understand.
-
"FUSION" is simply Yaesu's marketing name for the FCC designation of the C4FM modulation scheme.
-
YSF is using the same modulation system, but is not part of the Yaesu company. The YSF Reflector network uses software bridges and node radio's to connect different systems together. YSF is not WIRES-X. But YSF uses a Yaesu radio using the C4FM modulation
techniques to communicate with a hotspot set to YSF mode. Some Wires-X rooms are bridged to the YSF network (such as we do with SkyHubLink, and others such as the Wires-X room America Link) to connect the different services available. You cannot connect
to Wires-X with a hotspot, but are connecting to YSF Reflector node then bridged to Wires-X. Its all about the modulation that Yaesu radios use, which is C4FM. The modulation technique C4FM stands
for Continuous Four Level Frequency Modulation, which is a special type of 4FSK, which is used in conjunction with FDMA - Frequency Division Multiple Access.
-
YSF, while the acronym stands for "Yaesu System Fusion" really isn't part of anything to do with Yaesu the company. Another group of brilliant minds got together to use the C4FM modulation system and created the YSF Reflector network that allows bridging of
systems like SkyHublink and allows users of Yaesu radios to then be able to communicate across modes using the Pi-Star software, YSF linked digital repeaters, and hotspots to access as the Yaesu Wires-X system is proprietary and doesn't allow this to be done
easily, if at all.
-
WIRES-X is simply Yaesu's marketing name again for their proprietary system of linking repeaters across the internet. Again, being proprietary, it doesn't allow bridging in its own rights to other modes. That is where the YSF link and SkyHubLinks Hub server
comes in to serve.
SkyHubLink uses a server computer running software that interconnects the YSF Reflector system with the rest of the AllStar and DMR and other modes. See the diagram of this at:
https://skyhublink.com/connections/ We employ a node link radio that is on the YSF Reflector network, YSF 92722 on SkyHubLink, on the frequencies of the Moffat Water treatment plant on 448.350. This repeater
is always locked to WIRES-X SkyHubLink room 46361 for this reason. From the main SkyHubLink Hub server connected to the YSF Reflector network, it goes out over the "node" radio that talks to the 448.350 Fusion WIRES-X repeater using the C4FM "System Fusion"
modulation, making the connection work, and thusly, if you are any of the SkyHubLink repeaters, you are heard on the WIRES-X portion of the system, and vice versa.
Any questions please feel free to ask anytime!
