There is one minor fault (which has just occurred) in that the menu button no longer seems to work as it did. I think this is a minor fault and I have declared this to the new owner, who still wants it.
In the past the rig has been used to work lots of DX including the USA on 40, 30, 20 and 15m. The rig is a 4-band version with internal auto-ATU. The K1 is a decent little radio.
