Not a bad day in March on Long Island to conquer strobe noise in Radios!
Things that worked:
****Keeping power supplies at wingtips
****Not using shielded 5 wire that came with unit, but 3 wire #22 twisted and shielded and grounded at power supply with shielded heat shrink to cover cable splice going right out to head
****Using twisted #22 that begins right at head for position LEDs (not run inside of shielded wire with high voltage)
****Using a core on "high voltage" cable, but it must be located after the shield begins. @100MHz 100 ohms or more ohms seems to help the most
****Using #18 twisted pair to feed unit. Must be twisted right up to the power supply
