Advantage of DET
It enables DCS squelch operation even in poorer signal conditions.
Disadvantage of DET
When it is activated, suppose 2 stations are sharing the same channel and using the
DCS selective-calling technique and transmitting at the same time. After station A
with its corresponding DCS is gone, you may still hear station B even his DCS code is
different from A, although he can't open your DCS squelch by his signal alone.
