Excessive splatter?

Hello all! I've recently noticed on my 6400 that there seems to be excessive splatter or something else that's going on. It happens on all bands, but doesn't seem to hurt or harm anything. Here's a link to what's happening https://youtu.be/I35UEJsEiVE

    Hi Justin, you can't judge signal quality by looking at the transmit signal that way. If you want the real picture, you need to open a second panadapter and put the rig into Full Duplex (FDX). Then put the RX and TX on different antenna ports.

    Now when you transmit, you will see the signal as it comes off the air.

    There are several very good videos on YouTube describing the setup.

    Thanks for that advice KD0RC! I tried that, and it seems like it may just be local, just in case though, I did record it. Here's the link, https://youtu.be/v-zmxN5ms2o

    Your second video shows everything is fine. What you see in the second receiver will most likely be buried in someone's local noise floor. I wouldn't worry about it unless someone complains.

    HI Justin, those artifacts are at least 60 dB down from the carrier (the FCC requires -43 dB). The top of the signal is off scale, so it may be even more than that. In any event, you are producing a very clean (and very legal) signal over the air.

    The tx signal observed on the screen is just what “bleeds over” into the receiver before the final filtering of the tx signal.
