| Looks like raw 8 bit data packets (one or more silent symbols in between the data packets) The start/stop bits are basically reduced to a "silence" bit or bits. It really is not a binary sequence per se, but ternary (3k symbol, 1k symbol, silence symbol). Even though it saves on frame sync, this is not going to work as well as a binary system when there is HF selective fading. 73 Chen, W7AY _______________________________________________ RTTY mailing list RTTY@contesting.com http://lists.contesting.com/mailman/listinfo/rtty |
