Hello,
I am wondering if there are faster and more precise methods of finding milar frequencies than mine. I use two methods - one is rtl_power on my RTL-SDR and Raspberry Pi - it gives a waterfall of power vs time and frequency - it is precise but the output is some kind of "post factum" of action .
The second method is a cheap handled spectrum analyser RF Explorer - its limitations is limited to 112 points "on screen" resolution - so 225-380MHz band gives 155MHz span / 112 equals about 1.38 MHz resolution and we want 25kHz - finding a correct freq needs at least two measurements - wide one and a narrower.
Do you have any methods or hardware that can speed up the process of acquisition of new mil air frequencies?
