C4FM Multiprotocol Server

a solution for connecting repeater bridges and hotspots using the C4FM / Yaesu Fusion 2 amateur radio digital protocol with excellent operational quality and customized configurations. It is a project developed by Kurt OE1KBC. In Italy the reference server is YCS222 and is interconnected with the BrandMeister 2222 network and the DMRPlus networkfor a complete and widespread presence on the territory. This C4FM reflector is available to all amateur radio colleagues and allows you to simplify connection management through a single and practical dashboard. Furthermore, if someone wants to do without managing their own YSF reflector, they can now easily rely on this system to continue normal operation with the new resources available. The YCS world reflectors are interconnected, so it is easily possible to make foreign QSOs as is already the case for the DMR and DSTAR world. Let's see in detail the operating procedures.

• REPEATER : connected repeaters and hotspots.
• DVMatrix : Here you can see DG-ID groups being passed to other YCS servers (similar to interlinks with DMR and D-STAR).
• ACTIVITY : last stations listened to
• DG-ID : the available DG-ID groups. The X indicates that the corresponding DG-ID group is permanently connected to the respective repeater / hotspot.
• DG-ID-LIST : list of DG-ID groups with their descriptions.
• GROUP : the “Group” column shows the fixed DG-ID groups (a kind of Talkgroup statically in the DMR world).
• RX / TX : QSOs in progress are displayed in green (origin) and orange (destination) . After a transmission there is 30 second protection (displayed in blue) against raid so that the repeater / hotspot continues to receive on the previously used DG-ID group and not on another DG-ID.
• MODE : DN / VW mode. Please ALWAYS use DN on your radio at this time.
• DG-ID : name of the DG-ID group.
• TYPE : System (protocol) with which the repeater / hotspot is connected: DR-2X / IMRS, YSF, FCS
• DG-ID numbers with yellow background : DG-ID numbers that can be manually selected (on demand) but cannot be activated permanently. Duration of the request: 10 minutes. It can be deactivated instantly by sending the TX DG-ID 00 (ZERO ZERO)

Who can we QSO with on YCS222 All digital amateur radio systems are very dynamic, this means that changes and new implementations and interconnections can be present frequently . To see “who we can talk to” you need to see the

To give some examples, the connection in YSF mode (ID DTMF # 22201) is combined with Group 22 (DG-ID 22) which corresponds to Italy. BrandMeister Italia is connected to this Group (through TG 22292 MULTIPROTOCOLLO ITALIA) and TG 222 of the Italian DMR + network ( IPSC2-IT-MLINK and IPSC2-IT-RPTR servers ). A great opportunity to do QSO !! Let's not forget also the HBLink.BrandMeister open-source system always connected to this Group and to the XLX DStar reflectors . Another example: if I want to speak with the Lazio multi-protocol, I have Group 30 ( DG-ID 30 corresponding to TG 2230) available , forTuscany Group 41 (DG-ID 41 corresponding to TG 2241 ) is always multi-protocol . Other interconnections can be requested by writing to info@grupporadiofirenze.net or to the managers of the servers indicated.
