[Elecraft] K3 and YAMAHA CM-500

[ayoshida]

Hi all

Thanks for suggestions. My problem has been fixed.

a) Pin 1 is connected to Tip and Pin 7 is connected to sleeve.
b) Set FPH Bias and tap "7". Again tap "7"

Everything works as expected. I have same level now with FPH Bias.
I do not know why I need to tap "7"
