     Any sort of loop will work, the Adcock is really a sort of 
loop. Since great precision is not needed a small loop would do. 
Its a matter of getting readings from a number of separated 
stations and plotting them. I would give at least an approximate 
location. At higher frequencies a beam antenna could be used but 
at 4 Mhz a beam is too large but a loop is quite practical.
    If a fairly large number of stations hear the signal plotting 
relative strength might also give a clue as would daytime vs: 
night time strength. All crude but might at least tell if it were 
coming from the U.S. or somewhere else.
