>> I did go to the menu.  The CW KEYER was turned to "OFF".  I switched it to "Mode A"; still continued RF output.   I switched it to "Mode B", still continued RF output.  Same results with the key plug inserted or removed.  I returned the switch to "OFF".

>> Using the menu I switched the KEYING LOOP from "OFF" to "ON". The transmitting stopped and the receiver was working as normal.  Put the key plug in; keying had no effect.
>> Hopefully I'll have time this weekend to get the case off.
