[App_rpt-users] Crackle

On both my acid installations I have a crackle on the tail. I noticed this first on my first installation using usbradio. I have since installed a second node on a different repeater using usbradio and hear this same crackle. I have a third node using simpleusb and do not hear this crackle The only reason I think usbradio it's heard on the tail almost like the squelch trying to adjust itself to compensate for a static burst. Has anyone ever heard this before? Maybe I'm all wet with my usbradio theory. It never bothered me but a few people have noticed it too so I figured I would ask.
