Hello ,
when working with DX stations, I receive on the bands. lots of local interference from plasma TVs, phone chargers or power supplies for LED lighting. I made an external antenna and turned on diversity. I move the radius point in the circle but there is no reaction. I connected the external noise killer X-phase home made on the same antenna and there was a strong reaction. Do I need to set any additional parameters in setup Thetis? I connected antenna No. 2 to the RX2 BNC socket on the back of the anan 7000 DLE MKII. What else do you need to pay attention to for Diversity to work?

Depending on the band I'm working, I may need to change one or more of the options in the Phasing Control panel:

Hello Mark,
I have the same setup as shown in the screenshot. Today I switched the second antenna to the RX2 input and diversity started. work. However, this is a complicated process because a lot depends on the antenna and the type of interference. I decided to install a vertical external antenna, which will definitely improve the diversity operation to the noise coming from the outside. I am sending a screenshot of what it looks like on a day when the 80 m band is inactive. In the evening, when there is progation, this noise is less. If you have any advice on which vertical antenna to mount to eliminate this noise, please.

Set same band on both VFOs, A and B, or diversity will not work.

Thanks for the hint. Switched from 80m where diversity worked to show noise at 40m. At 80m I was reducing the noise and both VFOs were in sync.
