Why won't my Uniden UBC780XLT Scanner stop scanning?
- A
  Amy WilliamsAug 16, 2025
  If your Uniden Scanner won't stop scanning, you might need to adjust the squelch threshold. Also, check the antenna connection. Ensure that not too many channels are locked out, as this reduces the scanner's ability to find an active channel. Review each channel's frequency to confirm it's correctly stored in memory. It's also possible that none of the programmed frequencies are currently active.

  Patricia HardyAug 22, 2025
  If your Uniden Scanner isn't tracking an EDACS system properly, the logical channel numbers (frequencies) for the system might not be programmed in the correct order. Check frequency resources and reprogram. Also, make sure that all frequencies for the system are programmed. Check frequency resources.

  Amy BryanSep 1, 2025
  If your Uniden Scanner has improper reception, check the antenna connection or try moving and repositioning the antenna. You can also try moving the scanner to a different location. If you are in a remote area, you might need to use an optional multi-band antenna. Check with your dealer or a local electronics store for assistance.
