Hi, Artie The answer is "A" - everything goes through. According to some of the guys who have "taken D-STAR apart" (Robin AA4RC, Pete AE54PL), the DV (digital voice) signal has the low-speed data interleaved. Roughly translated, it's a little voice, then a little data, then back to voice, with some other "overhead" thrown in now and then. It would be difficult, I suppose, to separate them. So it all passes right through the repeater (and is also good on simplex). [Sales pitch ON] If you'd like to know more about how D-STAR is constructed, Robin gave a detailed talk at last year's Dayton D-STAR forum. There's a clip of it on my web site: www.arvideonews.com/Dayton The whole thing, several other D-STAR presentations at the forum, and the Friday night meeting (mostly fun stuff, but you get to meet more of the people who are moving D-STAR forward) is on the DVD - just $15 [sales pitch OFF]. 73, Gary KN4AQ ARVN: Amateur Radio//Video News Gary Pearce KN4AQ 508 Spencer Crest Ct.
