I'm traveling so cannot do any experimenting at the moment (I'm visiting your tax dollars). IF I'm remembering correctly in the past when entering a simplex DMR frequency the TS field would gray out. I was working on a plug yesterday and noticed that the TS field was NOT grayed out on simplex DMR channels and could be set (TS1, TS2, Auto). Even before this while doing SFR experiments I noticed different behavior depending on how the "grayed out" TS was set. I would set it in duplex mode and then change frequency to simplex which would keep my setting even though it was now grayed out. What I wonder now is if there is a NON DCDM capability at all? When fields grayed out before it was implied. Maybe Auto TS accomplishes this for all practical purposes. Am I right with assuming when using a normal repeater that it responds (handshake) to subscriber with a MASTER clock sync? With moto radios you could select whether radio could be slave, master, or eligible for DCDM. I don't think I've seen that with other brand subscribers.
