I am unable to test this unit and would not know how if I could. It appears to be in good condition: it has some light wear, but there is no evident damage (cracks, dents, etc.). It does not include any power cables, the key, or other accessories. It comes from the estate of a deceased HAM who also owned a radio station. Much of the equipment from this estate has worked quite well, though I make no claims this device is in any condition other than what has been mentioned. There are two units available. Each has some written notes on them which I'll keep in place. Notes and configurations on each device may differ.
