yes the status page shows fcs001/099.
When I PTT nothing on the sharkrf changes.
DP-ID is "Digital Personal" ID which is a unique identifier that every Fusion radio has from the factory. The pages from the FT-70 manual you attached are talking about when you go into GM (group mode) you can save other stations unique identifier "DP" ID to identify who in in that group you set up. DG-ID is for squelch that you can set up same or differently on TX and/or RX which is what you want to change on the fusion radio and the OpenSpot under the Settings tab in C4FM settings as SQL 0 thru 99 = DG-ID
