[Elecraft] Is this normal? KX3 ACC2 IO Lockup

[Don Wilhelm]

Dave,
Put a dummy load on the KX3 the next time you try that - it is going 
into transmit.

You have nothing connected to ACC2 - no voltage, no closed circuit. That 
means the voltage at ACC2 IO is LOw since there nothing applied to that 
input inside the KX3 - it is just a floating input.  Sooo, when you 
select LO=PTT in the menu, it asserts PTT on the KX3 - just as you told 
it to do.
