So I got my 2 dongles and started browsing the frequencies. I notice the different modes like usb lsb and others. What do these modes do? If I change to lsb I can hear beeps pulses etc but fm there is no signal. So how do I know which mode to use and why would I use different modes? What are their purposes? I just want to get a grasp and understanding on when to switch to appropriate modes. I am curious about the frequency ranges too. What frequencies contain certain data.
Im curious how to use it optimally so I can start making sense of this stuff. Any info would be great. Thanks!
