I am having a funny problem with a few of my collars this week. I am getting a loud deep buzzing sound when I get the gain over 2. Only happening on two collars, Any ideas?

have you tried replacing the 9volt in the reciever?

When that battery gets low it makes all kinds of weird noises... pretty sure thats what it is.

Yep, that worked. The batery reading was still showing "6" but all is well with a new one, thanks
