Independent Side Band. Used a lot by short wave feeder transmitters until the 80's, and previously by telephone companies in international links before satellite links became sort of a popular commodity,
I remember listening the ID of Tropical Telephone and Telegraph Company on my grandma's radio when I was a kid in the 60's. They used a partially supressed carrier (somehow understandable on a short wave AM radio). I also remember listening to VOA on ons sideband and AFRTS on the other some time later, when I was already a ham on my father's HRO-60. I have seen no software capable of generating it so far. Actually, it would require two sideband generators. I am not sure if a single sound card could actuallydo it. ISB has not been usual among hams, but could be interesting. Once I read a proposal for using SSTV on one sideband and audio on the other, but have heard noone doing that. 73, Jose, CO2JA --- Patricia Wilson escribió: > Pardon my ignorance but what is an ISB signal? > > On Sun, Oct 11, 2009 at 12:32 PM, rameuser <[email protected] > <mailto:[email protected]>> wrote: > > > > Does anyone know of software capable of generating an ISB signal? > The only soltion I am aware of involves using two SSB generators > on two sound cards.
