Sub-audible tones (CTCSS) or digital (DCS)?   Which do you use and why? Is one better than the other? is the digital coding more reliable than the sub-audible tones? I see that the repeater operators seem to always use CTCSS.   I am hoping this isn't one of those "Which engine oil is best?" topics?   I am trying to determine what channel and method of squelch to use between my base and the HT.   Thank you in advance...
