Ok. I understood.
I asked you about it because I built a Automatic Antenna Tuner controlled by Arduino for my Magnetic Loop.
For while I can control it using a Android Device.
My Idea is control my Antenna Tuner also via a modified version of a SDR program. So, instead tuning my Magnetic Loop Antena using a SWR meter,
I intent do that via receiving signal lavel.
In this case, I start transmitting after the system is coupled.
If you wish, you can see my Antenna Tuner working in my Youtube Channel (PU2CLR). Direct link:
