This Another way which was suggested to me as an improvement to my soundcard based VFSKCW program is to introduce a wobble on consecutive elements. For example, say the difference between the "dots" and "dashs" is 10Hz. My software detects consecutive dots or dashs and "wobbles" consecutive elements by some % of the difference, nominally 10%. So consecutive elements wobble by 1Hz. The amount of wobble is adjustable to allow better differentiation under marginal conditions. 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- ULF, ELF, VLF & LF Experimentation InfraSonic Experimentation Laser Comms DX Amateur Radio Astronomy =============================================
