You need to calibrate the sound card settings. I am not sure in DM780 but in MMSSTV you go to setup, Misc, then in the Clock settings set it for 12000 when running VAC
Hope this helps Bret WX7Y -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of John Vandenberg Sent: Saturday, January 17, 2009 11:04 AM To: FlexRadio@flex-radio.biz; John Vandenberg Subject: [Flexradio] FLEX5000A SSTV Running SSTV with DM780 using VAC (demo). The problem I have is that on about half the received pictures the slant is bad or the picture is partly shifted (horizontally anywere in the vert interval). The other pictures are perfect. Also how to do the SSTV calibration (don't find it in the menues) Any ideas highly appreciated.
