Instead of comparing the 300Hz power to a constant threshold, compare it to the power in nearby bins in order to determine S:N power at 300Hz. That should be self-adjusting. -- 73 de Brian, WB6RQN/J79BPL _______________________________________________ fldigi-alpha mailing list [email protected] https://lists.berlios.de/mailman/listinfo/fldigi-alpha
