Mysterious Fequencies / Groups on 396XT

My scanner keeps stopping on a few items I can not find anywhere in the programmed data in order to delete them. They are just noise, never nothing intelligible.



Examples from Screen:



Newport News

GRP:----------



Newport News

ID:3536

3536

S0:1-----------

GRP:----------



I have searched all frequencies list and they appear nowhere ??!! It says Newport News, but they do not exist.



Any Ideas??



This is driving me nutty.... :)
