anyone encountered this problem and can anyone point me in the right
direction to troubleshoot it? Thank you Sam in Colorado.

N0KEI-

While I haven't had that exact problem, I have had something similar.
It turned out that the rig was set for an automatic key but a simple key
was plugged in. The result was that one side of the automatic key input
was grounded by the single circuit key plug.

In my case, the keyed tones could be generated in modes other than CW,
even though the transmitter did not get keyed.
