Where does it say this? 73, Roger
Rule ten of DXCC makes it all about the operator's call signs (multiple). It doesn't have to be his equipment or station. If it is his equipment, he doesn't even have to be the operator as long as it is with (one of) his call(s).
The ARRL apparently doesn't have a problem with people using someone else's station to work DXCC. Following the rules, someone can earn DXCC and never have personally made a single contact, or a person could have DXCC and never have made a contact using his own station.
