Nino, I could certainly support "narrow" spread spectrum modes with higher baud rates if they can outperform other modes. Have you tried Chip modes with wider bandwidths (at least a voice width channel) on either HF or at least on VHF to see how they perform?
When you say 8 times more efficient for 2400 baud vs 300 baud, do you mean it is more robust or that the speed is that much faster? If Chip 64 was the bandwidth of MT-63 (either 1 or 2 KHz) and could have any baud rate, how would it compare with speed and robustness? 73, Rick, KV9U Nino Porcino (IZ8BLY) wrote: > while traditional narrowband modes can't make advantage of higher > baudrates, > because of the reduced sensitivity, "spread spectrum" modes can.
