The Band 3 topic you bring up again. I recall that your band pass filters were for Band 20. So I’m confused about that. Pointers appreciated.
I would think that the best way to go is to use this and to test each part of your rig in isolation and/or discretely.
Maybe LimeSuiteGui is a bit complicated for basic testing. Even though I know it’s designed exactly for that.
Or maybe you’re past the need for this. Sorry if I’m not offering anything new here.
I guess I’m acting as a sounding board…
Do you have one of those inexpensive SDR dongles for tx/rx tests?
