Yes (of course) and no. W1VD received me quite well a few weeks ago, see https://dl.dropbox.com/u/19882028/LF/07_July2012.jpg Not to forget W1TAG: https://dl.dropbox.com/u/19882028/LF/DK7FC_Juli2012.jpg So there is some propagation in summer but of course it depends on the solar activity. Don't know how the condx have been yesterday. > One point from previous trials , If Spec-lab is used with > Opera , then SL must be set to 48Khz sample rate , or OP can > loose low level decode sensitivity. Why do you think so? As long as the frequency range of a SSB bandwidth at audio levels passes through the SL filter, then it should be fine. So 8 kHz SR should be fine. Of course it depends on which shift frequency you have to use. I have to use 11 kHz shift and so i choosed a SR of 30 kHz. 73, Stefan
