The Granita board should already work down to 10 MHz. 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.

All existing SDR software should be supported via OsmoSDR.

Yes, it should work as a coherent receiver. There are some questions about unmatched I/Q pair trace lengths, but from what I heard from the experts as long as the clock is coherent (which it is), we should be able to correct those in software.

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.
