IF Bandwidth setting / dBm accuracy in measurements

I want to measure the accuracy of an unknown noise source from 15 - 25 MHz. (I have several I need to measure). As a test, I have a known calibrated noise source of 68 MK @ 20 MHz.

dBm accuracy

I've been using the Spectrum Analyzer software with my RSP1. I wanted to explore it's possibilities by measuring in dBm, the Temperature in kK of a known noise source.

VFO knob for RaspberryPi

Has anyone, or does anyone know of, designed and or build a VFO (external) device for the Raspberry Pi as a tuner? I know they have them for the Windows version of SDRUno. Wondered if anyone has made one work with the Pi version.

Re: Windows 7 driver issues - help

Ok, I tried one more time and I have SDRuno 1.13 installed and running on my RSP1. It probably took 15 minutes for it to install the drivers after "searching windows update" for something.

I've installed RSP1s and RSP2s on several computers so installing the software isn't new to me. I had it running on this computer until 2 days ago.
