After 3 minutes, QSYed to SEEDS which was in digitalker mode. Below is the best SSTV picture from SEEDS. Can anyone explain why the image is still noisy despite a full quieting 59+10db signal (with preamp on)?
The problem came from the background waves pattern as it was coming from an unregulated voltage or something is added in the signal from the original recording? I checked this week end on HF some SSTV transmissions HF and theses waves pattern where not present.
