Chris,
My guess is that you are hearing a low level digital noise (rather than
birdies) coming from the MCU as it illuminates the LEDs. The fact that
they disappear when you turn the LED brightness down leads me to that
conclusion.

With the antenna disconnected, I have noticed some very weak "birdies"
on most of the bands, with a 15 khz separation; most of them are below
the noise band level with a connected antenna; I made the test in a
remote place in the deep vcountryside in souith west of france, with a
KX3 poxered by battery ; natural or artificial noise level is very low.
but
these birdies disapear completely when the LED BRIGHTNESS COMMAND is
set to 1, and reapear when the command is set higher than 1.
