Rob, I have an SDR-100 as well which I use primarily for SWL'ing. I've been aggravated by the "DC Hump" as well and like you am wondering what can be done about it. I also have an SDR-IQ which isn't quite as sensitive as the SDR-1000 but works quite well and has no sign on the hump. I know that the SDR-IQ doesn't use a sound card and instead has the I_Q demodulator and decimator on board so perhaps that's why it doesn't have any hump, but it seems like this is a design defect with t he SDR-1000 that could be solved with a little effort.
