OK I was scanning with one of my SDS 200 scanners. Actually, I was scanning Vanderburgh P25 and SAFE T P25 systems. Went into menu and manage favorites and I decided to delete a system (conventional) that I wasn't even scanning. When the scanner went back to the scan screen hmmmm,...NOTHING TO SCAN. The programming appeared to still be loaded you could turn on and off the quick keys. Nothing to SCAN. ALL service types enabled, GPS was active even though I was home. Had to reprogram the SD card to get the scanner to scan again.
I just tried to reproduce this by deleting systems in the scanner but now it works as it is supposed to. Thank God for backups on computer. BTW, when I went to read the SD card with Sentinel it said the programming on every system had changed. Needless to say I told it to ignore those changes, cleared user data and rewrote the card. Works fine again. I have had issues with Sentinel changing stuff but not the scanner itself.
