> If you need to go lower, I (or someone else) would need to design a custom RFNM daughterboard for low frequencies. You could do direct conversion up to 150 MHz, so it should be a simple task and come with good performances.

If do ship oscilloscope daughterboard that you have on your site, would that work also as SW radio?

You'd probably want something way more sensitive than that, right? Something that goes well into the micro/nanovolts rather than millivolts. But it should be reasonably simple to do. Also the RTL board when designed with a good frontend should be a viable option.
