[Elecraft] K3s won't go into transmit

[Peter Dougherty]

Hi guys,
I think I may have either misconnected something or blown the PTT line after
re-connecting my K3s from stand-alone Field Day mode back to being integrated
into my main shack using MK-II hardware.  I cannot assert PTT to the radio via
any means except manually using the XMIT/tune button or CW keying via the
paddle. My footswitch, handswitch and MicroKeyer-II PTT controls are all
inactive, and I'm in a bit of a panic since I know I didn't change any wiring; I
just disconnected everything to bring it outside yesterday.

Any ideas where I can start to look?

For any of you MK-II users, I have the MK-PTT IN line going to the KEY OUT jack,
and the wire marked PTT-IN going to the PTT-IN jack. The MK-II will put the
radio into transmit for CW, but not for RTTY, voice keying  or any digital mode.
I'm beginning to think I may have damaged the radio at this point and could
urgently use some assistance.
