Except for the Simplex High Speed Data, (128K on 1250 Mhz) the i/o uses
an offset on DSTAR. 1292 uses either 12/20 Mhz. 440 in Temple uses 5
Mhz, and 2M uses whatever they can get. Look at the list of repeaters
on www.dstarusers.org for more details.
There is a delay caused by coding the voice in the transmitting
subscriber unit, and then decoding the voice in the receiving subscriber
unit, plus whatever delay is encounter in the repeater. There is also
delay in some squelch tail eliminator circuits - buffer the voice - and
chop off the burst of noise and unkey before it gets to the
transmitter. Works in function like reverse burst, but does not rely on
tone codes.
So far the only real argument deals with delay, and there are plenty of
analog repeaters with as much or more delay than DSTAR. Would running
your plain old FM repeater's audio thru a dsp board or an audio delay
for squelch tail elimination make it no longer a repeater ?

If the I/O is the same, it cannot "simultaneously retransmit" and cannot

Part 97 does not consider simplex repeaters to be repeaters.

My point exactly.
