I think ALE and HF DV could be a fantastic mix. It would certainly help optimise paths under some circumstances. Might not be so good for large roundtables (someone who knows ALE could prove me wrong), but certainly for point to point (e.g. distant mobile user to gateway) applications, I see ALE being very beneficial here. > >Take a look at DRM who is already doing it at a commercial broadcast level. > >Since DRM exists and is in use, then I guess the Digital Voice >(music) on HF HAS caught on. Haven't tried DRM on shortwave, but then again, I was never much of a SWL to begin with. Been a while since I've tuned a receiver outside the ham bands. ;) 73 de VK3JED / VK3IRL http://vkradio.com
