When I use lower band (7MHz, load DTV7 SCODE) it doesn't work, then I go in the high band (8MHz, load DTV78, DTV8 SCODE) and have channels and can watch TV. If I go now in the lower band (7MHz, don't reload SCODE) it works. This effect is for me a bug. > The fix for it should be at xc3028. Please propose a patch for it.
