The article at PA0FRI's website has some photos of the loop being laid out along a chalked line on a piece of plywood. The results appear pretty good.

In the simplest terms: Your receiver provides the carrier. See 'Beat Frequency Oscillator' at Wikipedia

To answer your last question first. I believe that Sharp receives it's tracking data over a DDE link while SDRUno receives it over a virtual comm port. I haven't used SDRUno with Orbitron recently, but as I recall WispDDE must be set up to emulate a TS-2000 radio to communicate with SDRUno over a vi...

Thanks Paul
I thought perhaps it was an electronic fuse. I have one of these on a supply for a Mini Whip. In order to reset it after an overload, I must power it down and turn it back on.

You need an old version of SDRSharp, version 1361 or earlier, the newer versions will not support the ExtIO plugin which is available here in the downloads section of this site. Also the demod and tracker plugin you need must be the DotNet 3.5 version. The old SDRSharp 1361 is here: https://www.qsl....

In SDRUno 1.22/1.23:
In the RX Control Panel:
Right click inside the frequency display area.
The Tuning Step Popup will open.
Left click on the desired Step.

The current frequency step is displayed in the upper left corner of the frequency display window.

Are you sure of entering the correct frequency? An FM broadcast on say 105.5 FM will be entered in SDRUno as 105500000, 1220AM as 1220000. Also use the correct mode AM, FM etc and bandwidth for the signal you are hearing. You should be able to hear and see signals on the spectrum display on the AM o...
