* AMS (Automatic Mode Select) System Fusion

System Fusion is Yaesu’s digital operating mode.  It only works with Yaesu’s newer mobile and HT radios.  The SLSRC C4FM System Fusion repeaters operate in AMS (Automatic Mode Select).  AMS mode works in Digital Narrow (DN), Wide Voice (WV), Frequency Modulation (FM) and Data.  If you transmit in FM, you will receive in FM.  If you transmit in digital C4FM (DN, WV, Data) you will receive in digital.  If a FM user joins a digital conversation, all the Yaesu radios will automatically switch to FM to continue that conversation.  In FM mode, you must use a CTCSS tone of 141.3 Hz to access the repeater.  If you are operating in FM mode, please check to see if a digital conversation is in progress (BUSY light + S meter bars will be present) before you key up.  If you have a FM only radio, use the CTCSS tone to squelch out the C4FM digital hash.  If you have a “Busy Channel Lock Out” feature on your radio, you might want to turn it on for this frequency.  There is no courtesy tone on the SLSRC System Fusion repeaters & there is a very short squelch tail.  Timeout is 3min.

In Aug 2018 Yaesu put together an “Overview of System Fusion 2” YouTube video that is very informative on C4FM.  I encourage you to watch this video to get up to speed on the System Fusion environment.

In Sept 2018 Yaesu put together an “Overview of DG-ID and DP-ID” YouTube video.  Go check it out to learn more about this ID standard.
