Just a note about feedback. Feedback is a particular sound caused by a particular thing. One cannot call the problem described here feedback because it's not caused by a microphone and speaker "connected" to the same loop. The different names for sounds cannot be used interchangeably. You cannot call a car horn a "hum" or the sound birds make a "rumble." We use the appropriate name for each sound. Why that is is above my pay grade. It's just the way it is.
This seems pretty basic and the reason it's important here is because it can be hard to diagnose problems through a forum and if we use the wrong words for things, and in this case we're deliberately doing so, it just makes it harder to solve for everyone having to deal with it, both now and in the future for people searching old posts.
Hopefully, the folks dealing with the problem can find an answer despite the mis-information.
Lets just call it the unwanted sound ...for me is not working well and if its a hum or a horn it's a sound that its not suppose to be there .
We need to find the cause of this unwanted sound , this is my set up
Gimble / iosd mini / fpv hub / avl58 transmitter
Cos it could be the new USB gimble or the fpv hub or avl58 , I would rule out the iosd but you'll never know and about the interference board some said it didn't make any differance with or with out it so .
If we could post the set up here maybe we will narrow it down before starting unplugging and pluging different components .
