This MFJ-422X Electronic Keyer on BY-1 Iambic Paddle, is in very good condition.
The paddle itself is in excellent shape.
The MFJ Electronic keyer appears to be working okay.
It runs on a 9 volt battery and an external power supply can also be used.
The previous owner has added a couple switches and 1/8 inch audio jacks.
I am not sure what they were used for but it is probably to use the unit with multiple rigs.
It is being sold as is as described.
