Re: [digitalradio] Re: How to choose Olivia tone/bandwidth parameters-- an idea
Hello Paul and all, You can found in my WEB site a paper (RS_ID_English.DOC file) which title is Digimode identifiers and which describes mainly Video ID and RS ID.

Re: [digitalradio] Re: How to choose Olivia tone/bandwidth parameters -- an idea
I seem to recall that the waterfall image (fax) has been available for some time with the digital image/data programs, e.g., WinDRM, and perhaps it was later adopted into some of the sound card programs? ARRL considers the mode to be digital J2D when sent as a sound card mode modulating an SSB transmitter. 73, Rick, KV9U Ian Wade wrote: That's exactly what I had in mind, but instead of sending text such as callsigns, you send some helpful information.

Oops, I should have read the rest of the posts first. Video ID - got it. I'll understand it more when I first see it.

No, not at all. Just watching the waterfall. I do not remember the little details. Patrick has replied as well, and you can look for them at http://f6cte.free.fr/PAPERS.ZIP, download the ZIP file and extract RS_ID_English.DOC. 73, Jose, CO2JA Paul wrote: Jose, But does that mean you need to be listening in Hell mode?

It's called Video ID and if you can see the waterfall you can read it. It blew me away the first time I saw it, I thought I was seeing things.
