[NLRS] No contest...

Speaking of LEDs and noise.  I noticed something a number of years ago while out in my rover while at stop-lights.
I'd be sitting there monitoring 2m SSB.  When I pulled up to the stop-lights, the noise level would go up a bunch.  And the noise would change as the stop-light flipped from Green to Yellow to Red.  I had  a crunch-craft beam pointing right at the stop light.  It certainly raised noise from over 100 yards out.

With the exponential rise in the use of LEDs it would not surprise me that the diodes and their power supplies are really adding a lot of noise to the VHF.
