WebMay 3, 2024 · As far as reliability, though DCS was designed to be a very reliable signalling format, DPL is designed so that out of every three cycles of the word, only one is required for decode. My suspicion is that persistent interference can render it unreliable compared to CTCSS. Sent from my SM-T350 using Tapatalk. WebNov 17, 2005 · In CTCSS/CDCSS decode modes there are more options. Let's talk about unmuting first. Standard unmuting allows the correct CTCSS/CDCSS detection alone to determine when the receiver unmutes. AND unmuting involves both the carrier squelch circuit AND correct CTCSS/CDCSS decoding to unmute the receiver. The carrier …
