So, it looks like the NWS had regenerated all the {radio}_same.zip shapefiles on the site back around August 2, 2020 -- they'd removed some data from those files (specifically the SAME/FIPS data), so the V3.03 script would just display 'undefined' for the SAME code.
I've written some scripts to run on noaaweatherradio.org and changed the generation program to include the SAME codes in the NWR-radios-data.js file which the script set uses.
So.. Version 3.04 is now ready, and as a plus, it includes the 'Remarks' section shown on the detail page for a NWR display.
The full package is available at
https://saratoga-weather.org/scripts-wxradio.php#wxradio for download.
If you're running V3.03 of the script, only two files have changed (NWR-radios.js, NWR-radios-inc.php) and can be downloaded from
here .. just replace the files on your site (no customization needed) and do a shift-reload of the page in your browser to get the new NWR-radios.js to load.
