HF on RTL-SDR

So it turns out, that just by changing a DLL file in SDR# and changing from Quadrature to Q Branch, you can get HF on a dongle without an upconverter or modifications to the hardware. And most surprising of all is it actually works ok. I do have some AM broadcast breakthrough and I will need to add in a Highpass filter to remove it, but other than that, it looks like it works quite ok.
