    Timing Advance Blip Help

    Hello
    I have about 3 cells in my timing advance log that reads very odd 20 sec in.
    Not sure what would cause this.

    Its a known issue with that dataloging software. That glitch happens when the timing advance goes Negative.

    What's the workaround people are using for this glitch if any?
