NOAA Weather Radio gnuradio receiver for RTL-SDR

NOAA Weather Radio is available in almost all areas of the country and a description of this service is available in the link below. http://www.nws.noaa.gov/nwr/ It is seven channels of NBFM centered on 162.475 MHz. Your local channel may be found here http://www.nws.noaa.gov/nwr/coverage/station_listing.html The GRC representation of a flow graph using RTL_SDR that will display all seven channels is seen below. This flowgraph will also display the entire band in the eighth plot. The sliders control squelch, RTL-SDR clock offset, a superfluous center of band control, and channel assignment. This flow graph will be avail shortly on my github repository. I am going to add a blog entry which will detail work underway, planned for future releases, and as always, it will always be GPL and your help will be welcomed. 73s Bob N4HY
