[Elecraft] K3s tx LED issue, need help

[Bryan Savill]

Here's my issue and it has just begun.
I'm using a Heil Proset with my K3s, when I switch to VOX the tx LED 
lights with no input.
With the headset on my head, if I touch the K3 case the LED goes out and 
I am able to tx while holding the case.
With the headset resting on my desk near the K3 the LED in not lit, but 
if I touch the headset the LED lights.
With the mic jack unplugged the LED does not light.
I've examined all jacks and lines
Seems like some sort of capacitance issue maybe.
Any help would be appreciated.
Thanks

73,
