I talk about LEDs quite a lot at work, Paul, in the context of using NVGs.  
Many airports and obstructions are now lit with LEDs with core wavelengths 
below 650nm.  There are filters in NVGs at that wavelength, for specific 
reasons, so the lights don’t show very well – unless they are cheapo LED which 
have a wider spread of wavelengths, I believe.

I wonder therefore if the cheapo LEDs are the ones that transmit and jam your 
radio frequencies.
