Pulsing noise on specific ant selection combination

Tom

I have strange pulsation that make work impossible. It is strange that I experience this problem only in specific combination of ant inputs.

Receiving and transmitting antenna should be different to eliminate the problem, for example ANT1 as receiving and ANT2 as transmitting....or vice versa.

RX A is not working with neither ANT1 nor ANT2 as transmitting antenna.

RX B is working with both ANT1 or ANT2 as transmitting antennas.

The same behaviour is persistent without actual antennas connected.

Please check video to understand the symptoms.
