2). How close is your pixel loop to you other antenna? Could the tuning of the transmit antenna be detuning your loop or interacting with it in some way.
Just a couple stabs in the dark.

Those signals you see come up out of the noise floor are valid JT-65 / JT-9 signals, that is what troubles me about this issue. It truly affects what stations can be heard or copied. I checked the switching voltage, no change. I do not have any ferrites on the power lead or the switching signal. On the video I am bypassing the ATU not activating it, so I doubt if it is RF getting into something. Thanks again for your reply
I would appreciate your findings from your pixel. it appears to me that the ATU is in the RF path for RX-A, I'm not sure why that would be from a design stand point. I am going to test with another antenna on the RX-A port. I think it will occur regardless of antenna type on the RX-A port.
I know this discussion was for the 6500, but certainly with the 6700, a single ATU cannot be in both RX-A and RX-B paths. I would not expect the 6500 signal path to be that different.

Perhaps a factory reset is in order. Something else to consider. Like all of us, you imported your profiles. Have you tweaked and resaved at least one default set of profiles under the new version? I would think that at least the GLOBAL profile might handle some features slightly different.
Thanks for your reply. Just tried a different antenna and I still see the issue. It does not appear to be as pronounced but the substitute antenna is not as quiet as the Pixel. I have opened a help desk ticket and received a reply from Dudley, I am confident He will get it sorted out. I will report back the findings.
