In the AnyTone D868UV programming software, there are channel options for both "Simplex TDMA" and "Talk Around". What's the difference?

If I recall correctly, DMR "talk around" and DMR simplex are actually the same. Each of these essentially use BOTH time slots without any time sync and only one voice path per channel. Simplex TDMA, on the other hand, uses either time slot 1 or time slot 2 and can accommodate two voice paths per channel, the same as DMR tier 2. Because of this difference, I don't think that DMR simplex is compatible with simplex TDMA.
Talkaround and Simplex are the same thing... It has nothing to do with Analog vs Digital.
OP is talking about chinese programming software not real life.Talkaround and Simplex are the same thing... It has nothing to do with Analog vs Digital.
"Talkaround" is in reference to repeater operation. When using a repeater your radio transmits on one frequency and receives on a different frequency. If you select the Talkaround option on the radio it immediately switches the transmit frequency to be the same as the receive frequency.
No. Talk around means talking on the output freq of a repeater, like was explained above. The “TAC” as in TAC310, is short for “tactical”. Many police departments have a main dispatch channel. But to keep traffic off the main dispatch channel, they will go to TAC1, or TAC2, etc. So to keep traffic off NA, after you make your contact on NA, you would go to TAC310, which doesn’t make sense because they are both on the same freq, & TS, so if one is busy, they are both busy.Bill - Thanks and you reminded me of something else I was going to write: "TAC" stands for Talk Around Channel. Hence there are DMR talkgroups labeled TAC310, TAC311, TAC312.... etc. In this case though the purpose of the "talkaround" is to avoid congestion of widely used talkgroups, such as the statewide or nationwide DMR talkgroups.

Yup, that's what it's coming to with 25 TG's jammed into 2 TS's.On both of my local repeaters (VHF & UHF) all TGs on slot 1 are PTT activated. On slot 2 every TG except True Local and Indiana Statewide are likewise PTT activated.
