[Elecraft] K3 Screen displays " ERR PTT " msg

[Don Wilhelm]

Dave,

If you really mean that nothing but power is connected, then your K3 has 
a problem and it is time for an email to K3support at elecraft.com.
But, if you have a key or paddle connected, or a microphone connected or 
the RS-232 cable connected, try disconnecting those first.
ERR PTT says something is trying to key the K3 at the time you power on 
- it will inhibit everything until the key closure is cleared.
Key closure can be actual key, paddles, PTT or DTR/RTS keying through 
the serial port.  Check that nothing is contacting the XMIT button too.

73,
