The 436 is the only digital scanner I have, so trying a different radio isn't possible.
Programming it via the Sentinel software. Have tried ID scanning, ID search, and the Discovery function on the radio, all to no avail. Also tried a frequency search through the 800 band, also with nothing. All done from within visual range of their tower. Picked up VIPER just fine, and another, what sounded like paging system.
Due to the age of the information in the database I even tried programming using every available trunking option in the Sentinel (P25 X2, P25 One Freq, etc)
The manual claims and indicator of ENC will be shown when it detects an encrypted transmission, none was ever displayed. Only DAT, and on very rare instances LNK. But never any audio.
Tried using the Discovery function to look for new talk groups on VIPER thinking maybe they had switched to it, again nothing, least not from New Bern.
