But if it's a repeater AT ALL, it is PROHIBITED in the 145.5 - 145.8 sub-band! I wasn't commenting on the frequencies in use and the legality therein; I was just commenting that it can be serving two different functions concurrently.

The first concept of D-STAR that I saw used 10 Ghz for the point to point connections between sites. Internet is cheaper and we are hams. Some time back I said if it walks like a duck, looks like a duck, quacks like a duck, it just may be a duck. I believe DSTAR is a repeater. I also

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 Jamey
