Very interesting. Have you seen the extremely slow CW
program called "Argo"? Written by Italian hams and may be of interest to you. I have it if you can't find it (very unlikely.) Seems to me I saw something on slow data a while back as well, but don't recall what or where. Please post any follow-up info or results to the group. Thanks.

No I haven't seen it, but I don't think you can really use CW for this to full effectiveness even if you've got a 1 hz analog bandpass filter, because it's hard to decorrelate a signal that slow with all kinds of intereference. I'd have thought you'd need spread spectrum. But I'm really not up on this kind of thing. |
