I am getting proper communication with the radio but I can hear (<20kHz) the radio when it is communicating. The appropriate noise cancelling procedures have been taken on the power supply line. Is this normal for operation? If not, what might be causing this hum?
Iām not sure whats causing this but its not an expected behavior. Does all you 868LP modules have this issue? I would suggest you to get it replaced by contacting point of purchase.

I have experienced several of our modules chirping, not all of them. The radios are in an enclosed case that is in high humidity environments, so perhaps the sealing capability of the case has failed. I wanted to see if this was a known failure point for the modules. Thank you for your quick response.
