Re: BITX40 - 50Khz birdies

Possibly from oscillator of Arduino? Or if the LCD has an LED back light. I have noticed LEDs that light up my microphone buttons do this.

Hi,
BITX40 and Arduino connected. LCD 16x2 and rotary encoder.
Notice there are some birdies at approx 50Khz distance.
Anybody noticed this also and know the root cause?
