NOAA Weather Radio on SDRTouch

This is a short demonstration of the NOAA Weather Radio stations in the VHF band (162.400 MHz to 162.550 MHz) as picked up by an RTL-SDR dongle on my Pixel 7 Pro using the SDRTouch app.

Notice that the frequencies 162.400, 162.450, 162.500 and 162.550 appear to be coming in loud and clear; the remaining 3 channels, 162.425, 162.475 and 162.525 are either incredibly weak or non-existent at my location.
