The best way is to show it with a photo

Re: Signals moving the opposite way of my tuning
Hello,
the signals moving from left to right must be "ghosts", that is mirror products due to overload/intermodulation in a tuner stage. Try to reduce tuner gain.
Are there strong local stations near you?

I suppose they are artifact (images and so on).
It is common in a "low cost" sdr systems.
Trying to reduce those artifact -- setting gain, bw, filtering etc... -- is part of our hobby...
Maybe not the best part... sometime can be annoying...

Re: Signals moving the opposite way of my tuning
I have one station near me "BBC radio Devon" i have another cheap (£5) radio and it picks up this station no matter what frequency you are tuned to if it is connected to my big antenna.
Talking of the antenna it is probbaly the worst you could think of in the worst location
Yes thats right a cb aerial covered on both sides by a roof by any chance was the roof acting as a mirror?
Also dont laugh too much at my artwork i never got a proper picture of it
