What to do if the Albrecht Receiver scan won’t stop?

  Emily GriffithJul 31, 2025
  If the Albrecht Receiver scan won't stop, several factors could be at play. First, the squelch might need adjustment. Also, ensure that the antenna connection is secure. Another reason might be that one or more channels are locked out, so verify that the channels you want to scan are not locked out. It's also possible that the channel’s frequency isn’t stored in memory, so ensure the channel’s frequency is stored. Finally, the channel might not be active; in that case, wait for a transmission on the channel.

  Anthony FletcherAug 9, 2025
  If you're experiencing improper reception with your Albrecht Receiver, start by checking the antenna connection and try moving or repositioning the antenna. Additionally, try moving the receiver to a different location. If you are in a remote area, consider that you might need an optional multi-band antenna. Check with your dealer or local electronics store.
