The NTIRN system has some users that their subscriber radio will over-the-air send a plain text alias. The SDS series scanners cannot decode the alias at this time, but with an SDR radio ($35 each - but 2 SDR radios is recommended for optimal decoding) and software (I use DSDPlus Fastlane - $25 lifetime) you can decode them using your computer.
Last I checked, those of us that monitor NTIRN with DSDPlus have decoded over 5,000 aliases (all aliases are uploaded to the cloud and if you have received a radio that someone else has previously got their alias, it will download it from the cloud, so you aren't waiting to recapture what others have done already) - but my last trip near Hurst (early March) didn't pick up any, so their radios may not be sending the over-the-air aliases.
The problem is, the file DSDPlus produces would have to be manipulated quite a bit to get something to load into Sentinel (or the SDS scanner app of your choice to make it useable for that scanner.
