[Elecraft] [K3] Birdies

[John Bekema]

I am not sure if this is related to any wifi/switching power supply

Check an other picture:

The P3 is in 'Fixed tune mode' (so when you turn the dial, the green
bar will move)
You see that the 'birdies' move, quickly. At 50.024 you see a CW beacon.

When removing the antenna, the 'birdies' stay.
