[digitalradio] Re: Digital SSTV?
Yeah, Have not tried to copy "digital" SSTV for a long time. Got tired of fighting with all the RTTY signals in the PSK part of twenty meters this past weekend, so went up to 14.233 and tried using DigiTrx, didn't work. Guess they are now using HamPal now on "digital" SSTV. Two different formats, DigiTrx I think uses RDFT and is the "older" and first try at digital SSTV, HamPal is using DRM or Digital Radio Mondiale type encode/decode. Signals were to noisy and got to many errors that I gave up. I didn't feel up to asking for fills, would have taken all afternoon the way the noise was at my QTH. Went down to 14.230 and even with noise was at least able to view some kind of an image on Analog SSTV. Guess this upcomming weekend, January 14th, is another PSK contest, a total waste of time for me. Anyone want to mess with DominoEX or the newest version of MultiPsk, Patrick added "video ID" in the waterfall on some of the modes. For instance sending CQ on Olivia 500Hz, 16 tones one can see in the waterfall "Oliva 16T 500" before the CQ text is sent. The "image" is pretty weak, but at least a start to ID on all the MFSK type modes such as Olivia. Even works for BPSK31. The version number is 3.12 MultiPsk. http://f6cte.free.fr/ 73, Jerry - K0HZI --- In digitalradio@yahoogroups.com, "Danny Douglas" <[EMAIL PROTECTED]> wrote: 3 Choices are 2 too many for me.

[digitalradio] Re: Digital SSTV
Doc, The first RDFT "digital" SSTV software was built on Linux. One needed some of "CYGWIN" files installed on Windows HDD for it to work. I am not sure if there is "DRM" for hams on Linux yet? But for RDFT see: http://www.svs.net/wyman/examples/hdsstv/ There is also a digital sstv group on Yahoo: http://groups.yahoo.com/group/digsstv/ 73, Jerry - K0HZI --- In digitalradio@yahoogroups.com, kd4e <[EMAIL PROTECTED]> wrote: > > Any idea why they chose the WAV file format? > > Is it, and the MS version of windows, more a matter > of familiarity or is the WAV file format really the > most efficient of the many alternatives? > > Also, anyone know if there are Linux apps that handle > these formats, since an increasing number of Hams are > moving to Linux? > Thanks! & 73, doc kd4e Need a Digital mode QSO?

Re: [digitalradio] Re: Digital SSTV?
Yea Jerry I know the feeling. I did get a computer upgrade, thanks to my daughter buying herself an newer one and giving me her old 1.2 gig. I don't think that digital sstv is for me. I used to listen to the net during the week days on 7.173 and I could only get 10% of the pictures. I gave up and deleted that stuff off my computer.
