LINK, DATA, Slot1

[MrFTAMan]

While scanning with the SDS200, I see the P25, P25 P2, and others pop up on the top of display. I understand the P25 and P25 P2. I see DATA, LINK, Slot1. What does these mean? Will there be any others that would pop up?

I don't have a manual nearby but I believe DATA means it's receiving control channel data LINK means receiving voice SLOT1 refers to which time slot is being used
Phase 1 uses frequency division multiple access
Phase 2 uses time division multiple access - one of two time slots is used effectively halving the bandwidth from a normal 12.5 kHz to 6.25 khz

LNK appears when data is received on a voice channel in Receive/Hold Modes.

DAT appears when data is received on a control channel in Receive/Hold Modes.

ENC appears if the channel is receiving encrypted voice and is muted in Receive/Hold Modes.

Full list is here (scroll down past pink tables)
