Hi
I am also facing same issue. Yes this crosstalk is from other two ports at wifi card.
In my setup I am using Intel NUC where WiFi card is installed and I am using IPX to RP-SMA cables from card to outside for antennas connections.
In order to be sure about working condition of each antenna port at 2.5GHz as well as 5GHz, I have used cable connection instead of over the air between transmitter and receivers each one by one for all antenna ports outside and I have completely sealed the input ports of other two antennas while extracting CSI from one but still i can see spikes received by other two antennas ports.
In the end I came up with thoughts that due to not having proper coverup/shielding of the ports at the WiFi card I am receiving the spikes.
My question: How strong (in dB) are those spikes?
