I have similar issues with the H3-2d gimbal. I tried various methods of trying to suppress the interference including choking all connections with ferrite beads in an attempt to present a high impedance to the interference but without success.

It's obvious that once DJI release an updated version of a product they cease support of the legacy items.

Could solve this problem with a Ground Loop Isolator between Zenmuse and Video TX
