Replacing power from computer to separate power supply for Nooelec SAWBird H1+ LNA on Ptarmigan Array Milky-Way-Hydrogen-mapping computer

In order to stop me making the mistake of forgetting to run “Bias-tee-on” each time I restart this computer, I have added a separate 5V power supply to the LNA – also means I needed extra DC-block between LNA and SDR.
