A good way to find any specific station on CW is using the reverse beacon network (RBN). A search for Tony reveals he was on 20m today and heard in France.
These spots can also be served by several DX clusters, so if you have a cluster client with alarms (like the VE7CC one??then you can get your computer to bleep when any of the RBN receiving stations gets a CQ from G0HUZ/mm. I worked Tony on one of his previous travels using this system.
