[Elecraft] CM500 headset on K3S and KX3?

[Nr4c]

 I adapters needed. 

CM500 plugs right into the rear Mic and Phone jack on K3(s). 

Also the KX3, just turn OFF Bias and Buttons. 

PTT is available on rear PTT RCA jack on K3(s) and Tip and Shield on KX3 Accessary jack ( a 3/32 TRS Jack next to the I/Q  Jack).   Use switch of your choice;  an old J38 works real well here.  Use the “shoring bar” for long conversations.
