I get the following error when trying to execute line 2 (the RadarServer declaration):

Are you, by chance, coming from a non-edu domain? Since the TDS is locked down to .edu only, siphon will only work there?
I need to catch the error and be more clear about what's going on (obviously), but the root cause is that you're getting a 403 (Unauthorized) error.
Sorry, we kinda have to be careful of data charges. One option, if you're looking for data from the last two weeks is to use our server at http://thredds.ucar.edu/thredds/
The other option is that you can browse and downloda the data over http directly from the S3 bucket at https://noaa-nexrad-level2.s3.amazonaws.com/index.html
