What to do if there is audible interference in Alto Professional Extender transmission?
- W
  William MiddletonAug 6, 2025
  Audible interference can be frustrating. To address this, first, ensure the receiver and transmitter are within 200 feet (60 meters) and have a clear line of sight. Make sure the receiver isn't near metal objects or devices that could cause RF interference. Try changing the RF frequency and channel on both the transmitter and receiver, ensuring they match. If using multiple transmitter-receiver pairs, use only one pair at a time, or ensure they aren't using the same or adjacent frequencies. Adjusting the squelch control setting may also help. If a higher squelch setting is needed due to poor signal quality, try eliminating the source of interference or switching the channel to maintain signal range.

If issues persist, try changing the RF frequency and channel on both the transmitter and the receiver, making sure they are set to the same channel.

Also, check that both the transmitter and receiver are set to the same RF frequency and channel. Ensure that the receiver and transmitter are within 200 feet (60 meters) with a clear line of sight, and that the receiver isn't near metal objects or devices causing RF interference.
