Some WWV action
And no, all the spikes to the left aren't noise, they are stations. 
Slide over just a hair, and there is all of 40m and 20m including everything in between. 
Zoom in on 40m since I have my dipole hooked up 
Reach over and flip the upconverter out Here are some FM broadcast stations on the same 40m horizontal dipole. 
I am still playing around with gain setting but it is pretty awesome. Get yours here |
These SDR receivers have impressed me, but I've never spent enough time to completely understand their operation. What is used to allow the reception of the lower frequencies beyond it's advertised range of 24-1800Mhz? I'm sure that I am missing something obvious...

The most common method is to use an up converter. I use the Ham it up and like it. The video I posted is using the airspy's extra ADC and sampling direct, this can also be done with RTL dongles but you have to be careful |

My problem is that I'd have to buy a separate computer to run it as well, which is what largely keeps me out of data land in general. I've got a netbook that I'm currently using periodically, but that is inadequate for SDR.
They claim this runs 24mhz-1.8ghz, how are you getting HF on it? |
