My 1500 no longer keying externally

Hi Tim, Thanks for reply.

Yes, CWX works fine.

Yes, I have straight key (right now) connected directly to the key jack on the 1500 front panel.

As to settings, they appear to be OK to me, but I've written down most (except those that are default or cannot affect keying), but cannot see a way of attaching a file to this reply and cannot seem to paste them into this message.

The drag and drop did not work for me.

Here's the file that I typed up copying from the screens: ( X indicates box checked)

Hi Tim,

In my previous list, in the interest of brevity, I did not mention items if they were NOT checked.  Therefore, using a straight key plugged into the FRONT (no back jack as you said), Iambic is not checked.  Here is the relative portion of my previous list:

DSP->Keyer
  CW pitch freq 600 hz
  Break in  X enabled
  Delay ms 300
  Connections:
    Primary: radio
    Secondary: none
  X Disable UI MOX changes
  Options:
    X Sidetone
    X 2-wire cable
    AGC/ALC - n/a

Iambic is also not checked on the screen display either.

TNX for the rapid reply, appreciated.  Will try that shortly and if reset works will let you know, else will start ticket.  As I said originally, the keying used to work but I thought I may have changed something in the settings that killed it.
