The standard Yellow LED resistor is 3.3K.
The Yellow LED typically uses about 3.3ma, though it varies a bit depending on the LED and specific purpose of the controller (ie: LVD).
R4 = 130 ohm
R5 = 8.2K typical, could be vary widely depending on the application.
Never had any noise issues before.
110' is a long ways.
I have no clue what radar would do to it.
Ross,
Is high HZ noise like that visible to the human eye?
I do not understand how it could oscillate slow enough to be detectable by eye.
Woof,
After trying it with the long wires disconnected, and if that solves the issue,
Might try connecting the remote Yellow LED in parallel with one fet's resistors, and a 100nF cap too. It couldn't hurt.
