I'm still waiting on the band-pass filter so I've been messing around and trying to understand what is going on with the interference I am getting on 144MHz. While listening to the TX0 transmitter using my RTL SDR dongle I noticed something strange. There is a little "tail" that can audibly be heard and it can be seen on the waterfall. I took a screen video of this and shared a link to the video. Can anyone else confirm that their transmitter has this tailing off signal? Or maybe it's just a strange artifact with my SDR dongle?

The video is in 1080P so you can make it full screen to see better.
