Good idea for strong signals Andy, but for the task in hand you would need to 
accurately position them between interfering Loran spurs. Also a 7Hz wide 
signal would seem to be outside the 2Hz across the screen currently necessary 
for Larry to see a 500mW signal from the UK.

But, if the resulting tone sequence from your receiver could be automatically 
decoded into a character on the screen........
