The first concept of D-STAR that I saw used 10 Ghz for the point to

Wonder how much of the delay is inherent in the subscriber units, and
how much is attributed to the repeater ? Measure response on simplex,
then through a repeater, unless of course, these ducks aren't repeaters,
then it won't matter. Coffee time, Steve NU5D /K5CTX B, Temple, Texas

It's not a dumb question, but it is a common misconception.
The answer is, no.
If the I/O is the same, it cannot simultaneously retransmit and cannot
be deemed a repeater under the current Part 97 definition.
Part 97 does not consider simplex repeaters to be repeaters.

1. The repeater input and output frequencies are different.
2. It is TRUE full duplex, simultaneously retransmitting what it receives,
with only a few millisecond delay attributable to the bit regeneration process,
no more than is seen with many analog repeaters' anti-kerchunk delays.
3.

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
