[AMRadio] Viking Ranger problem

Is there a by-pass cap on the ¼" phone jack?  Usually, there's another 'leaf' on the jack that shorts out when no plug is inserted so that the rig does key up when put in the CW position.  

Check the inside of the plug for stray wires that might be shorting the tip and ground together.

After the physical inspection, check the clamp tube and its associated circuitry.

Good luck!
