There is no rule dictating USB or LSB on the bands (except 60m) but calling CQ on 20m LSB is like winking in the dark. You know what you are doing but nobody else does. You may as well turn the volume all the way down and call. You can also cause unnecessary QRM by calling on 14.200 LSB when someone is on 14.195 USB for example. Sticking with the proper convention is always the better idea. Personally I do not like mode versus frequency anyway. We in Canada have bandwidth emission rules that allows us to operate pretty much any mode as long as it fits in the bandwidth allowed which is typically 6 KHz on the HF bands. I can operate SSB voice on 14.001 USB legally if I want and even use narrow band FM on 21.105 if I want too as long as I watch the deviation. Not that I would mind you, but I could. I get a kick out of a lot of USA stations telling me I am out of band when operating USB 0n 14.125 or 21.150. <gotproof>
