Pier, can you clarify what you mean by a single key? Do you mean a straight key, or a single lever paddle?

I¡®m usually using a single key and switched it with one that has a reversed polarity. If I change the setting under menu=>CW Key=>Rev (Enabled/Disabled) nothing changes on the key input. One key would then still work properly and the other one have a infinite tone when plugged into the 3.5mm jack. I¡®m using firmware 1.23.09. anybody else noticed this stange behavior? Looks like the settings in the menu are not working?
?
