No different than if you were sitting in front of the station itself. ONLY time that may be different is if you are operating a remote via a RF control link...but the rules have been changed over the DECADES so that one ID, your callsign would take care of everything..BUT if the rmt station is a club station with a different callsign, you must ID the AUX station as well..(IE W5XYZ and W5ABC aux or control) The rules do NOT require a separate suffix for the control station anymore as they USED to..
