I am designing a custom 9600 baud link using a voice channel with the following specs: BW: 100-5Khz S/N = 35+ dB. Are there any "rules of thumb" about choice of carrier freq 2K ? 3k ? What about FSK deviation? With this type of system how does modulation index affect performance? High speed data communications is new to me; audio & RF is my thing. This link would not have any error correction other than "parity". "Shannon's law" shows this to be practical; but I am at a loss for what would be optimum. ? -- Chris Scott, C/E Public Radio, Western KY Univ, (502) 745-3834 SCOTTCR@WKUVX1.BITNET fx off: 745-2084 fx hm: 781-1232
