I spent a few years working (??) on the MV Southern Cross, callsign C6HK9, as a musician and found the Ukrainian crew and British radio officers to be most friendly and helpful. I was permitted to operate my QRP (low power - up to 5watts) 20 meter CW morse transeiver from the aft crew deck and used my callsign of G0RDO/MM (and also VK4CXO when in Australia). Below is a picture of the ship anchored off Padang Bai, SE Bali.
